Introducing the AgDroneTM System

HoneyComb’s Agricultural Drone (AgDrone) System has been specifically designed for farmrelated purposes including scouting, mapping, and precision agriculture. This is embodied in the 

platform design, onboard imaging systems, software, and data processing services. Other 

applications outside of agriculture including Forestry, Land Surveying, Exploration, and others 

have also been pursued with the AgDroneTM System; however, if your intended use is outside 

of agriculture please contact HoneyComb directly prior to operations.

Common Terms

UAS – Unmanned Aerial System, refers to the system as a whole including the aerial craft, ground 

station and other associated components.

UAV – Unmanned Aerial Vehicle, refers to the actual vehicle excluding ground station and other 

supporting devices.

Drone – Colloquial term for Unmanned Aerial Vehicle, referring to the actual flying device.

Safety Precautions 

IMPORTANT: Before attempting to operate the AgDrone and any of its components, read

through the following safety guidelines to prevent personal injury and damage to property. Do 

not power-on any equipment or attach any batteries until you have reviewed the material below. 

The HoneyComb AgDrone is an autonomous Unmanned Aerial System (UAS) designed to 

provide aerial imaging for agricultural surveying. To accomplish this task, the AgDrone uses 

electronically powered components and some potentially hazardous materials that must be 

routinely inspected and handled carefully. The following section covers some general guidelines 

for handling and operating the AgDrone System safely.

Limitations - Only operate the AgDrone during daylight hours in clear weather conditions and 

always maintain visual-line-of-sight (VLOS) during flights. The AgDrone must be operated 

primarily by the Pilot-in-Command (PIC) and facilitated by a Visual Observer (VO). The 

AgDrone should never be operated if a discrepancy is identified during inspection until 

corrective action is taken.
6

General Safety Practices

Flight - The AgDrone system must only be launched, flown, and landed in locations where it is 

safe to do so. Keep the aircraft away from obstacles and people when flying - especially while 

launching and landing. 

HoneyComb recommends flying the AgDrone UAV at an altitude of 400 feet (122 meters) above 

ground level. Lower altitudes increase the risk of collision with ground-based obstacles and 

higher altitudes violate U.S. Federal Aviation Administration (FAA) regulations. Do not use the 

AgDrone in areas where there is a risk of interference with other aircraft, especially within five

miles of any airport. 

It is unsafe to fly the AgDrone in winds exceeding 15 knots (17mph). Significant winds may 

cause less stable flight trajectories, resulting in reduced image quality and flight duration. Still 

weather conditions are best for flying.

The AgDrone system is not waterproof. Do not operate in rainy weather; serious damage to the 

electrical system may result. If rainy conditions develop mid-flight, land and recover the aircraft 

as safely and quickly as possible, and pack up the other components to avoid water damage.

Batteries - Lithium polymer (LiPo) batteries are extremely powerful, but can be unstable if 

mishandled or damaged. Read all warning and safety information provided with the batteries 

and charger, and follow these guidelines:

- Always charge (balance) batteries in an isolated place away from flammable material.

- The HoneyComb batteries and charge station must be used exclusively with each other, 

and never with other brands or styles of battery or charger. 

 

- If storing the batteries for more than three weeks (over the winter, for example), use the 

charge station to place all batteries in Storage condition.

- Always store and transport charged batteries using the included LiPo bag.
7

Handling - The fully-loaded carrying case, including the AgDrone and all of its components,

weighs approximately 70 pounds (32kg) and comes equipped with wheels for easy transport on 

smooth flat surfaces. Observe safe lifting practices while handling the unit and do not lift the 

fully-loaded case alone. 

The AgDrone UAV is covered with a Kevlar-composite exoskeleton with narrow edges along 

the rear of the wings (elevons). Be careful when handling the AgDrone and keep all body parts, 

clothing and other materials clear from the propeller of the AgDrone. Never handle the AgDrone 

near the motor and propeller when the AgDrone is connected to a power source. See figure 1-1

below for the suggested grip when handling the AgDrone.

 

 Figure 1-1: Demonstrating ideal grip for handling the AgDrone

- Carry the AgDrone by gripping the 

front of the wing as pictured.

- Avoid holding the AgDrone by any 

of the moving parts such as the 

elevons, servos, or propeller. 

- Always ensure that the AgDrone is 

powered-off when performing a 

preflight or 50-h inspection.

- Use this grip when preparing to 

launch the AgDrone

Theory of Operation

The AgDrone system is designed to be easy to operate, with minimal training and basic computer 

skills. The aircraft can be launched by hand with no special equipment.

The path of the aircraft is guided by pre-planned instructions from the operator, with the actual 

flight behavior controlled by an advanced autopilot system. Launch, flight, and landing require 

minimal interaction from the operator.

Cameras onboard the aircraft capture geo-tagged photos of the area beneath the flight path. 

These photos can be in the visible spectrum, or more sensitive to infrared (IR) light. The 

cameras store the images on SD memory cards inside the aircraft and telemetry information is 

collected by the autopilot. When the photos and telemetry are downloaded, they can then be 

digitally stitched together into a comprehensive view of the flight area in both visible and NDVI 

views.

The methods and technology used to acquire this imaging have an inherent margin of error and

will capture close representations of the actual field or crop being surveyed. Analyzing the 

results of the survey can give valuable information about vegetation health - providing insight 

into issues of water use, fertilization, physical damage, and more. Users are also able to export 

vector files for use with various farm management software other precision-agriculture 

equipment.

Operation Overview

Levels of Flight Automation - The AgDrone operates in three different modes: Primarily it uses 

Automatic and Fly-By-Wire (FBWA) and occasionally uses a third mode, Return-to-Launch

(RTL).

The AgDrone remains in automatic mode during normal operation, but there may be 

circumstances when user input is necessary to manually divert the aircraft from its planned 

course using fly-by-wire mode. 
10

Automatic Mode – Select this mode by flipping the RC channel selector switch to the upposition (labeled “0” on the controller). Heading, altitude, and speed are all controlled by the 

autopilot as the aircraft performs pre-set instructions and automatically triggers the cameras.

Although the AgDrone can operate without user input in automatic mode, the operator still has

the ability to send commands that are moderated by the autopilot. 

The left thumb-stick (throttle) allows the aircraft to increase its cruising speed. It is not

recommended to do this except when necessary due to windy conditions as it significantly 

reduces battery life and may result in lower-quality image output.

The right thumb stick (directional control) allows you to “nudge” the aircraft off of its planned

path. Once the stick is released, the aircraft will immediately return to its previous path and 

continue on to the next waypoint. This should be done in the event that a previously unseen 

obstacle (trees, power lines, other aircraft, etc.) is identified.

Fly-By-Wire Mode - Fly-by-wire (FBWA) is a semi-automatic mode that allows the pilot to 

send commands altering the AgDrone’s path. The autopilot still enforces some parameters to 

stabilize flight behavior, but less so than automatic mode. Select FBWA by flipping the RC 

channel selector switch to the down-position (labeled “2” on the RC transmitter).

IMPORTANT: In fly-by-wire mode, the autopilot does not enforce any limits on altitude so it is

possible to crash the aircraft if directed down toward the ground. 

Fly-by-wire is typically used only if a flight plan has been altered unexpectedly. Some situations 

that call for this mode include but are not limited to:

- A new obstacle appearing in the aircraft’s path and requires redirection

- Flying conditions have become unsafe and the aircraft needs to be landed abruptly

- A strong tailwind causes the aircraft to miss its landing pass 

- The aircraft has entered return-to-launch mode and must be recovered

*There is no fully manual mode available on the AgDrone system.
11

Mode Selection & Controls – The pilot in command only needs to manipulate the controls 

explained in this section; the various other knobs, buttons, and switches are deactivated and 

should be left alone (see figure 1-2 below).

Channel selector switch: this determines the AgDrone’s mode of flight.

IMPORTANT: The controller should always remain in fly-by-wire mode with the throttle down

(0%) until the aircraft is prepared for takeoff and ready to utilize automatic mode. Keep the area 

near the motor and propeller clear when the system is powered-on.

Control sticks: these allow the user to manipulate the direction and throttle. The operator can 

direct the aircraft in fly-by-wire mode, and “nudge” the aircraft in automatic mode.

IMPORTANT: Keep throttle at 0% in fly-by-wire mode when handling the AgDrone. Throttle 

should be at approximately 60% to maintain altitude in fly-by-wire mode.

Return-to-Launch - The AgDrone is programmed with a Return-to-Launch mode that will 

guide the aircraft back to its home location and loiter above until further instruction is given. 

You may never encounter this mode during normal operation, but it is in place to prevent 

damage to the AgDrone and any people nearby in the event of a lost-link or low-battery scenario.

Some situations that can initiate RTL mode include but are not limited to:

- AgDrone loses communication with the RC transmitter

- Battery reaches approximately 20% charge during flight

- User command (flipping channel selector switch to middle position)

- Requesting an RTL command in Mission Planner

Once RTL has caused the AgDrone to enter a loiter pattern, you will need to plan a landing 

sequence or manually bring the aircraft down using fly-by-wire mode (see Mission Planner

section).

Emergency Maneuvers

If dangerous conditions emerge during a mission, the operator must do whatever is necessary to 

mitigate the danger to nearby people or property, even at the expense of the AgDrone itself. 

Below are some possible situations that may require emergency maneuvering.

Obstacle Evasion - If you must evade an obstacle mid-flight, use FBWA mode as a last resort. 

The first best practice for evading an obstacle is to “nudge” the aircraft in automatic mode, as 

this is a more stable maneuver. The next best practice would be to manually initiate RTL mode 

by flipping the channel selector switch to the middle position.

Once RTL mode has guided the AgDrone to loiter above the home location, you can plan a 

landing sequence to bring the aircraft down or continue the mission by specifying the next 

waypoint to follow.
13

Lost-Link Procedures – If the AgDrone loses communication with the RC transmitter, there are 

a series of failsafe behaviors depending on the duration of the lost-link.

- Initial Lost-Link: Mission Planner will immediately alarm the operator of a lost-link 

status and will continue flying the planned path for up to 10 seconds while trying to 

reestablish communications.

- 10 Second Lost-Link: Mission Planner will continue to alarm the operator and the 

AgDrone will begin a circular loiter pattern at the approximate location where the lostlink occurred for up to 30 seconds while trying to reestablish communications.

- 30 second Lost-Link: Mission Planner will continue to alarm the operator and the 

AgDrone will automatically initiate RTL mode and loiter above the home location. At 

this proximity, the AgDrone should be able to reestablish communications.

- No Communications: If lost-link status continues and the aircraft cannot reestablish 

connection with the RC transmitter, the AgDrone will remain loitering above the home 

location until connections are restored or the battery power is depleted.

- Depleted Battery: In the event that battery power is depleted mid-flight, the first 

component to lose power is the motor. With no propulsion, the AgDrone will rely on the 

autopilot and control surfaces to gradually descend in the circular (spiral) pattern. Keep 

clear of the landing zone as the AgDrone will have minimal flight control and may 

approach the ground at high speeds.

Emergency Landing – The worst-case scenario for emergency maneuvers is the event of a crash 

landing. This is an absolute last resort and should only be executed after exhausting all other 

options. If there is no better alternative for evading an obstacle, then the safety of people nearby

is the top priority. 

If an emergency landing is necessary, use fly-by-wire mode to guide the AgDrone away from 

potential dangers for people nearby and seek out the most reachable but isolated area to bring 

down the AgDrone. Attempt the crash landing with the lowest possible airspeed and gradient 

percentage to minimize damage to the AgDrone and property nearby.
14

HoneyComb Process Guide

3. Ensure that batteries and powered components are fully charged

4. Clean lens covers and clear airframe of debris

5. Ensure that motor bracket is securely fastened to airframe

6. Inspect propeller for smooth operation, chips and dents, and remove debris

7. Check elevons and servos for structural defects or obstructions

8. Ensure that winglets and lid cover are securely fastened to the airframe

9. Check the following values in the FLIGHT DATA tab of Mission Planner before launch:

- SatCount is 7 or more

- DistToMAV is 50 or less

- Gps HDOP is 3 or less

- Altitude is 5 or less

- Heading (red line) is pointing in the same direction as the aircraft.

10. Clear launch zone of debris and unnecessary personnel

11. Check surrounding airspace for obstacles and adverse weather conditions

Prepare for Flight – After reviewing the operations manual, follow this guide for regular flight 

procedure after completing the preflight checklist. Refer to the respective chapters for further 

detail on the steps below.

1. Power-on Components – Boot the system in the order listed below and ensure that the SD 

cards are inserted in the front payload bay before powering-up the AgDrone.

a) Power-on RC transmitter in fly-by-wire mode with throttle at 0%

b) Power-on mission planning computer (telemetry antenna attached)

c) Connect battery to the AgDrone (disarmed – blinking red light)

d) Listen for start-up beeps (multiple tones), wait for readiness beep (long tone)

IMPORTANT: Boot the AgDrone UAV facing north for best orientation accuracy. 
15

2. Mission Planner

a) Open Mission Planner and create or load a mission

b) Adjust flight path for landscape and weather conditions

c) Click CONNECT and wait for Mission Planner to connect to the AgDrone

IMPORTANT: Select the FLIGHT DATA tab in Mission Planner and check the following values 

before launching: SatCount is 7 or more, DistToMAV is 50 or less, Gps HDOP is less than 3, 

and Altitude is 5 or less.

3. Launch the AgDrone

IMPORTANT: Carry the AgDrone so that it is facing forward for best orientation accuracy.

a) Approach the launch zone (AgDrone should remain disarmed)

b) Arm the AgDrone (push and hold arming button until light is solid-red)

c) Test elevon function (move directional stick on RC transmitter)

d) Grip the front of the AgDrone wing (see figure 1-1) 

e) Select auto mode from the RC transmitter and wait for the propeller to spin up

f) Hand-launch into the wind, travelling a flat and level path towards the Loiter WP

g) Observe mission, maintaining visual line-of-sight (VLOS) of the AgDrone UAV

h) Adjust flight path and assist with controls as needed for obstacles and landing

IMPORTANT: Observe the flight path at takeoff and prepare to cut the throttle if the launch 

appears to be unsuccessful. 

Failed Launch – If the AgDrone fails to takeoff, prevent damage to the motor by selecting flyby-wire mode with the throttle at 0% while still airborne. If the propeller spins against the 

ground, the motor fuse will fail and will need to be replaced. Access and replace the fuse under 

the payload bay while the AgDrone UAV is powered-off.

4. Recover the AgDrone

Mission Planner

Introduction

The HoneyComb system uses open-source software called Mission Planner to pair the AgDrone 

with Google Maps and guide the aircraft. Mission Planner allows you to create missions for the 

AgDrone that can conveniently be saved and loaded for future use. 

The HoneyComb system is designed to work with Mission Planner under the factory default 

settings provided by HoneyComb – do not alter these default settings to ensure safe operation of 

the AgDrone. 

NOTE: Do not update Mission Planner unless instructed to do so by HoneyComb. The software 

version installed on the provided computer is set for HoneyComb’s operation and updating it 

may change factory default settings, altering flight behavior.

IMPORTANT: If Mission Planner becomes slow or unresponsive, close the program and 

disconnect the telemetry antenna; then reconnect the antenna and reboot Mission Planner. If 

problems persist, reboot the mission planning computer and software to start over.
18

Create a Mission

Use Mission Planner to locate your field and specify the flight path for the AgDrone to follow. It 

is important to check that the map on mission planner is consistent with the actual field since the 

satellite photos may be outdated. Observe any unforeseen obstacles (buildings, power lines, 

trees, etc.) before accepting your flight plan. 

1. Locate Flight Area – Scroll and zoom on the map interface to locate your flight area. Click 

and drag the Home Location to the desired position, or specify a location using latitude and 

longitude coordinates. When the AgDrone UAV is powered-on in the field, Mission Planner 

can reset the Home Location to the current position.

a) Select the FLIGHT PLAN tab in Mission Planner

b) Input latitude and longitude coordinates in the text boxes below Home Location on 

the right side of the window

 You may use www.latlong.net to convert a street address into coordinates

c) Scroll and zoom to navigate the map interface and click-drag the Home Location

marker to the desired position

Figure 3-1: Mission Planner flight plan screen. Access this screen by clicking the FLIGHT PLAN tab 

(1). Enter specific latitude and longitude coordinates for your mission using Home Location (2).

Prefetching Map Tiles 

Holding the alt key, left-click and drag a portion of the map to outline the area where you’ll be 

operating. Give yourself some space on all sides of the field. See figure 3-2 below.

Figure 3-2: Prefetching map tiles for the area of operation.

Right-click on the map to bring up the menu shown in figure 3-2. Select Map Tool, and click 

Prefetch. A status bar will report progress as Mission Planner stores the map of the area 

selected. Allow the process reach at least zoom level 18 for adequate clarity on the map. Levels 

beyond 18 will be unnecessary for the user; repeatedly press the esc (escape) key to cancel 

fetching of the other zoom levels until the process has completed. 

Figure 3-3: Showing prefetching progress. Press (esc) to cancel zoom levels beyond 18.

21

Create Loiter Pattern

Loiter is a pattern that the aircraft will follow as it climbs to altitude and is where the AgDrone 

will go in an RTL situation. Right-click on the map to bring up the menu. Select Loiter and

click Circles. (See figure 3-6 below). 

 

Figure 3-6: Create a circular loiter pattern. 

NOTE: The Waypoints table on the bottom of figure 3-6 (1) shows the pitch and altitude for the 

“TAKEOFF” command. As you create more waypoints, they will be detailed in this table. Click 

and drag the green bar if the table is not viewable (2).

A pop-up window will open, as seen in figure 3-7. Make sure the value for Loiter Turns is set to

“2” and click OK.

The loiter pattern will be automatically generated at the map position where you right-clicked to 

open the menu. The center of the pattern will be denoted by a green marker identical to the home 

position marker and labeled “2” (See figure 3-8). Click and drag the marker to reposition the 

loiter waypoint.

Figure 3-8: Loiter area (waypoint 2) shown adjacent to home location. Notice the addition to the 

waypoints Table.

Loiter is the first destination that the AgDrone will navigate to upon launching. It is best to 

launch the AgDrone into the wind, so position the Loiter waypoint in the same direction that you 

plan to launch the AgDrone.

IMPORTANT: The loiter area is where the aircraft will be climbing to altitude, so it is especially 

important that this point is far away from trees, structures, power lines, and other potential 

obstacles.
23

Draw Field Shape

Use the polygon feature in Mission Planner to define your field shape. Mission Planner will 

automatically generate the most efficient flight path within that shape. Right-click on the map, 

select Draw Polygon, and then click Add Polygon Point (See figure 3-9). 

Figure 3-9: Select Add Polygon Point to begin defining the shape of your flight area.

The location where you right-click will be the first position of the polygon. If you wish to place 

it elsewhere, click-drag the polygon marker to a corner of the desired flight area. Continue 

adding points to define your field shape. Click and drag the points to adjust the polygon shape.

Figure 3-10: Two polygon points have been connected. Continue left-clicking to add polygon points and 

define the shape of your flight area.
24

Generate Flight Path

Right click and select Auto WP from the menu, then click Survey (Grid). Mission Planner 

automatically generates a flight path in the specified polygon (see figure 3-11). 

Figure 3-11: After completing the polygon, select Auto WP and click Survey (Grid).

Survey (Grid) Window – The Survey (Grid) window displays the proposed flight path and 

parameters. The path is shown as a series of yellow lines connecting green waypoints numbered 

in the order that the aircraft will fly. Adjustments should be made for unique field conditions.

Figure 3-12: Survey (Grid) window shows the proposed flight path (1). Set altitude to “122” (2) and 

select Canon A2300 camera (3).

Adjusting for Wind - You can adjust the direction of your flight path to combat adverse wind 

conditions and increase the quality of imagery collected. It’s best to fly perpendicular to the wind 

and make up-wind turns after each lap. For example, in a north or south wind scenario, adjust the 

angle to fly east-west (see figure 3-13 below).

The example below assumes a moderate wind blowing from north to south. To achieve a flight 

path that sends the AgDrone perpendicular to the wind, adjust the Angle (deg) field by clicking 

on the arrows or manually typing a value between “0” and “360” (degrees). At 90 degrees, the 

AgDrone will fly east-west laps instead of north-south laps (see figure 3-13 below).

Figure 3-13: Adjust the angle of the flight path to make laps perpendicular to the wind (1). It is best to 

have the AgDrone make up-wind turns (2). Check Advanced Options to make other modifications to 

your mission (3).

Currently, the mission begins at waypoint 1 near the home location in the southeast corner of the 

field. In addition to making passes perpendicular to the wind, it’s best to also have the AgDrone

turn against the wind at the end of each pass. This aids in maintaining a stable flight path, 

yielding better image quality. Figure 3-13 (above) shows the mission flying correctly given the 

wind conditions, and the turns (waypoints 2 to 3, for example) are going upwind. 

Still in the Survey (Grid) window, select the Grid Options tab (Advanced Options must be 

checked to access this tab as shown in figure 3-13). Under Grid Options you can change the 

StartFrom value which determines where the AgDrone begins collecting data.

In the example below, StartFrom is set to BottomRight which is ideal for the given wind 

conditions. Once you’re satisfied with the flight path, return to the Simple tab to confirm the 

flight parameters and accept the mission. 

Figure 3-14: Adjust the StartFrom position to ensure the AgDrone flies the most efficient path.

Make sure Camera top facing forward is checked and Add Takeoff and Land WP’s is 

unchecked. Also check that the Distance value under the Stats table does not exceed 40km.

Figure 3-15: Double check these values in the Survey (Grid) window before clicking Accept. Check 

Camera top facing forward (1). Uncheck Add Takeoff and Land WP’s (2). Distance less than 40Km

(3).

Check & Accept - If you are satisfied with your flight plan, click Accept to confirm and close 

the Survey (Grid) window. After accepting the flight plan, the Survey (Grid) window will close 

and return to the FLIGHT PLAN tab view of Mission Planner – showing the previously created 

polygon and the newly created waypoint path on the map. The next section explains how to set a 

descent and landing path for the AgDrone.

Accepting your flight path and closing the Survey (Grid) window will return you to FLIGHT 

PLAN view. The waypoints (including home and loiter locations) will be displayed over the 

polygon and a complete list of the waypoints and commands are listed in the waypoints table 

(see figure 3-16 below).

Figure 3-16: The flight path and polygon are shown on the map along with the Waypoints Table list. 

Notice that the waypoints go from “Home” to “2” to “4”. This may seem oddly numbered, but if 

you look in the Waypoints table you’ll see that “3” is actually a command for the camera system 

to initiate and not a geo-tagged waypoint. 

This happens again where the mission has been completed at waypoint “19” but “20” is a 

command to shut down the camera. Do not be alarmed that the camera commands show an 

altitude of “0”; this is normal and will not be reflected in flight behavior.

NOTE: If you need to edit the mission for any reason, it may be best to clear the mission and start 

over (right click and select Clear Mission).
28

Define the Descent & Landing

Once the flight path has been created, the last step of mission planning is to create a Landing. If 

no Landing is defined, the aircraft will simply return to the home location in a loiter pattern after 

completing the mission.

This process will involve manually creating a few waypoints to add to your flight path, and 

decreasing the altitude gradually so that the plane will come to rest in the desired area. 

Clicking on the map at this point will add a new point to the polygon, so you must first get out of 

polygon mode. Right-click on the map, select Draw Polygon, and click Clear Polygon (see 

figure 3-17 below). This will delete the polygon, which is no longer necessary once the 

waypoints have been created. 

Figure 3-17: Clear the polygon and begin creating new waypoints for descent and landing.
29

Initial Descent - With the polygon cleared, you can begin adding waypoints for Descent and 

Landing. Take note of where the AgDrone is ending its mission and how it can get to your 

desired landing area. Left-click where you want to place the next waypoint to create it. You can 

edit the altitude from the Waypoints table and click-drag the waypoint to reposition it.

Figure 3-18: Waypoint 21 has been added, with a default altitude of 122m.

Figure 3-19: Waypoint 22 is created near 21 and will be set to a lower altitude.
30

Continue Descent Path - Set as many waypoints as necessary to facilitate a landing sequence 

that descends gradually and leaves a clear path for the AgDrone to touch down. Most landings 

can be accomplished with 3 waypoints (including the final landing waypoint discussed later). 

Avoid making sharp turns during this sequence – the straighter the landing path the better.

It is best to plan descent against the wind when available. If you must plan descent at a 

crosswind or tailwind, allow extra space assuming the AgDrone will drift with the wind. In the 

following example the AgDrone is landing in the same field that it was imaging. In other 

missions you may plan your landing away from the flown field pending your surroundings.

Landing Waypoint - After creating some waypoints for the landing sequence, locate where you 

want the AgDrone to touch down. At that spot, right click, and click Land from the menu. This 

will create a final waypoint (23) under the “LAND” command which will cut power to the motor 

and have a default altitude of 1 (meter) as shown in figure 3-20 below.

Figure 3-20: Landing waypoint (23) is added with extra space provided in case the AgDrone UAV drifts 

with the wind.

NOTE: This process may take some trial and error. Remember that it is always possible to clickand-drag or delete waypoints to get your desired landing path.
31

Adjusting Altitude - Starting at the first waypoint after the “DO_SET_CAM_TRIGG_DIST”

command, reduce the altitude of each waypoint in succession. A good landing will be achieved 

when gradient percentages are all less steep than -15% (see figure 3-21 below).

Figure 3-21: Adjust altitude for the appropriate Grad % in the Waypoints Table (highlighted in blue).

In the figure above, notice the altitude adjustments during descent. At these positions, the 

AgDrone will successfully descend and land. Grad % should never exceed “15.0” during the

landing sequence; the final (land) Grad % should be closer to “10.0” to ensure a safe landing 

without damaging the AgDrone. 

If you are unable to achieve the proper Grad % values with altitude adjustments, you can clickdrag the waypoints to different positions, providing more space to make the descent. You can 

also create additional waypoints to alter the path of the descent as needed, but maintain a straight 

path (no spiraling down or zigzag paths).

Connect & Write Waypoints 

After completing the mission plan, Click CONNECT (top right of screen) and await 

confirmation of the connection between Mission Planner and the AgDrone. Next, click Write 

WP’s (green menu buttons on right of screen) to send the mission to the autopilot. 

IMPORTANT: After connecting, click the FLIGHT DATA tab and look at the SatCount

(satellite count) value. Do not launch the AgDrone if SatCount is less than “7”. Also check that 

DistToMAV is less than “50”, Gps HDOP is less than “3”and Altitude is less than “5”. 
32

Saving Waypoint Files

To save a set of mission waypoints, right-click on the map, select File Load/Save, and click

Save WP File (or use green menu buttons on right of screen). It is recommended to name your 

waypoint file with a name that describes the location, wind direction and date of the mission. 

Figure 3-22: Save the waypoint file using a descriptive name.

Loading a Saved Mission – Some circumstances may call for flying the same mission pattern 

throughout the season (assuming like-weather conditions exist). Rather than planning a new 

mission for the same field, loading an already saved mission is more efficient.

Within the FLIGHT PLAN tab, right-click on the Mission Planner map to bring up the menu, 

select File Load/Save, and click Load WP File (or use green menu buttons on right of screen).

NOTE: You may want to save alternate versions of the same mission area to account for different 

wind conditions. Consider this variation when naming your saved missions. For example: 

“field_C1142_May13_EAST”, or “field_C1142_May13_North”. 
33

Best Practices for Mission Planning

Follow these general guidelines to ensure a safe, effective mission and high-quality data output. 

Flight - HoneyComb recommends only flying the AgDrone at an altitude of 400 feet (122 

meters) above ground level. Lower altitudes increase the risk of collision with ground-based 

obstacles. Higher altitudes violate regulations of the U.S. Federal Aviation Administration 

(FAA). 

The AgDrone must maintain a minimum airspeed in order to stay airborne. It banks to turn (no 

“turning on a dime”), and climbs and descends gradually to get where it needs to go (no hovering 

or dropping). Be mindful of these limitations when designing missions. 

GPS technology has an inherent margin of error. The waypoints programmed by the Mission 

Planner may be off by a few feet in any direction. It is not recommended to fly the aircraft into 

any tight spaces, near obstacles, or on routes that require extremely high precision maneuvering.

It is best to fly when there is no wind; however, it is sometimes necessary to fly in breezy 

conditions. In relation to the wind, there are a few best practices to keep in mind. When 

possible, start your mission on the downwind side of the field; if the wind is blowing from 

northeast to southwest, start the mission in the southwest corner. 

It is recommended to fly the main legs of the mission perpendicular to the wind. There is a 

parameter available on the Survey (Grid) screen, which allows you to alter the angle of the flight 

path. Use the arrow buttons in this field to raise or lower the angle, and change the orientation of 

the flight path. If the wind is blowing from northeast to southwest, for example, the flight path 

should be oriented from northwest to southeast. 

Landing - The last leg of the landing path should have a gradient of no more than ten percent 

downward (-10%). This is to prevent the aircraft from coming in too steeply and damaging the 

equipment onboard. Plan the altitudes of your landing waypoints carefully. 

It may be easier to achieve a shallow gradient using the longer dimension of the field. One way 

to reduce the gradient of a flight leg is to make the leg longer without changing the altitude drop. 

If there is significant wind in the field, try to face the aircraft into the wind on the final leg. 

Try to avoid making sharp turns (turns tighter than 90 degrees) with the aircraft at altitudes lower 

than 100 feet (30 meters). 
34

Flight & Preparations

Before heading out to the field, check that all components are loaded into the carrying case and 

batteries are fully charged (balanced). Visually assess the components on the AgDrone for 

excessive wear or structural defects that may inhibit safe operation and good image quality.

Pre-flight Inspection

Always visually inspect the AgDrone and components before flight. Propellers should be free of 

any chipping and debris, and lens covers should be free of blemishes. In general, look out for any 

loose or stuck equipment and cosmetic flaws that may affect normal flight behavior. Refer to the 

Maintenance & Inspection chapter for more information.

Installing LiPo Battery

When the AgDrone is ready for a mission, open the lid cover to expose the front payload bay and 

connect a fully balance-charged LiPo battery via the yellow male XT60 connector inside the 

AgDrone. 

An audible beeping pattern will emit from the autopilot module to notify that power has been 

connected. The arming button-light will flash intermittently to notify that it is powered-on, but 

disarmed. It will remain so until being push-held for 3 seconds which will arm the AgDrone.

Another beeping tone will be emitted when the AgDrone is ready for radio communications. If 

communications are not acknowledged, then reboot the AgDrone and check that the RC 

transmitter is on and the telemetry antenna is connected to Mission Planner.

IMPORTANT: Boot-up the AgDrone with the front facing north and carry the aircraft facing 

forward for the best orientation accuracy.

NOTE: The XT60 connection between the battery lead and the AgDrone lead can be very snug 

and may be resistant when being pulled apart. To disconnect, grip both XT60 connecters with 

finger tips and press knuckles together for extra stability while pulling the XT60 connectors apart 

from one another; this prevents excessive force on the cables.
35

Launching & Recovery

The HoneyComb training program instructs operators on safe practices for handling and 

launching the AgDrone, which can be done by hand without any special equipment. Refer to 

figure 1-1 for proper grip when handling and launching the AgDrone UAS. 

Launching - Clear the launch zone of any obstacles and debris. Stable footing on solid flat 

ground is important for a safe launching technique. Move the directional control (right thumbstick) to test elevon function.

Arm the AgDrone and quickly return hands to the suggested grip on the front of the wing. Hold 

the aircraft away from your body. Move the RC channel switch up to automatic mode (position 

“0”) on the RC transmitter, and the propeller will spin up after a couple seconds.

You should feel the forward-force from the AgDrone when the propeller is spinning. When 

ready, throw the AgDrone outward so that it travels a flat (or very slightly elevated) path and 

avoid putting any lateral rotation about its center axis (yaw) or banking angle on the throw. Once 

released, the AgDrone will progress toward the loitering waypoint.

NOTE: The AgDrone performs best when booted facing north and carried in a front-facing 

orientation and launched into the prevailing winds.

Recovery – Always disarm the AgDrone immediately when recovering it from a landing or 

failed launch. Use proper grip when carrying the AgDrone back to the launch zone and visually 

assess the system for discrepancies before attempting another flight. 

Failed Launch – If a launch appears to be unsuccessful, quickly move the channel switch to 

FBWA (backward position) and lower the throttle to 0% to avoid running the propeller into the 

ground. In the event that the propeller runs against the ground, the internal 40-amp fuse will 

blow to save the motor from burning up. Recover the AgDrone and check the system again 

before attempting another launch.
36

HoneyComb Connect

Use the HoneyComb Connect application installed on the mission planning computer to 

download from the AgDrone and upload to HoneyComb’s servers for processing. HoneyComb 

Connect can store several downloads before uploading, but it cannot download multiple missions 

at once. 

Extracting SD Cards - Access the SD cards (imagery) and load them into the card reader. The 

third SD card that stores telemetry data stays inside the AgDrone and will make a wireless 

connection to HoneyComb Connect when the AgDrone is powered-on.

Download Mission Data – Open HoneyComb Connect from the mission planning computer), 

and plug the loaded card-reader into the USB port. Await recognition of the data (two imagery 

cards and one telemetry card). Select the Download tab, and then click the Download button. 

If experiencing an error during the download, reboot the application. Downloading the data will 

also clear the memory of the SD cards so they will be ready for the next flight, but the data will 

be retained within the Connect application.

Upload Flight Data – Select the Upload tab to view the files that have been downloaded. Click 

the Upload button and an authentication window will pop up. Enter credentials for the online 

user account and files will begin transferring after authenticating.

Online User Account – Log-in to your HoneyComb account at farm.honeycombcorp.com to 

view your mission data. If you haven’t created a HoneyComb account, click Register and fill 

out the necessary information to sign-up. 

Troubleshooting – If data is missing or corrupt, an error message will appear to explain the 

problem. If you encounter problems handling your flight data, report the problem to HoneyComb 

customer support to begin troubleshooting. If you encounter problems during download or 

upload, you can close the program and reattempt the process. If problems persist and your data 

cannot be uploaded through connect, Customer Support can assist you with salvaging your flight 

data.

Components Guide

This section explains the common use of the AgDrone’s primary components. These 

components are modified from their factory settings to HoneyComb’s special configurations. Do 

not attempt to alter these settings. 

Figure 6-1: Primary components of the AgDrone system include the RC transmitter, mission planning 

computer, LiPo batteries and charge station (some accessories are not pictured).

RC Transmitter

The Spektrum DX6 operates at 2.4GHz on a DSMX channel and requires four AA batteries for 

power. HoneyComb includes these batteries and a wall-charger cradle to keep them fresh for 

every flight (battery status reported on controller display). Refer to the Operation Overview

chapter for more information on flight modes and controls.

Mission Planning Computer

The Microsoft Surface tablet includes Mission Planner, HoneyComb Connect, instructional 

guides and tutorials, and various other factory-installed programs. Also included with the tablet 

is a SD card reader, AC power adapter, and rubberized case with a keyboard. A 915MHz 

telemetry antenna attaches to the tablet via USB connection during mission planning and flight.
38

LiPo Batteries

A single lithium-polymer battery pack supplies power to the autopilot, motor, camera system, 

and other components onboard the AgDrone with extra batteries included with the system for 

continuous flying. The LiPo battery pack includes a wire harness for the balance plug and lead 

cables (see figure 6.2 below). It is critical to handle these batteries carefully and review the 

following procedures for properly using, charging and storing them.

Figure 6-2: LiPo battery pack and wiring harness. The white balance plug (1) is only used with the 

charge station. The lead cables with a yellow female XT60 connector (2) are used with both the charge 

station and the AgDrone.

Balance Charging – The HoneyComb LiPo battery packs each contain three cells and should be

charged using the Balance charging method to preserve their output and longevity. Other 

charging methods will top-load and bias some cells over others, so balance-charging is 

necessary. See the Charge Station section below for more information on proper setup.

Battery Storage – When storing these batteries for a long period of time (more than 3 weeks), it 

is critical that they are charged to a proper level to avoid bloating and depletion. 

The LiPo battery charge station has several preset programs, including one for long-term storage. 

This mode will charge the battery to proper level to ensure longevity. Be sure to keep batteries 

stored in the included LiPo battery bag regardless of how long they are being kept unused.

IMPORTANT: If the outer casing of the battery pack is cracked or misshapen, or if the wiring 

harness becomes loose or disconnected, discontinue use of the battery and contact HoneyComb 

Customer Support to have it replaced and receive instructions on proper disposal of the battery.

LiPo Battery Charge Station

This charge station is capable of charging many varieties of batteries but HoneyComb LiPo 

batteries should be used exclusively with this charge station and only under the settings 

designated in the following procedures. 

Balance Charge Procedure – Follow the procedure below to properly charge LiPo batteries 

before flying a mission. The AgDrone UAS will not function properly if charging procedures are 

not followed correctly.

IMPORTANT: Do not connect LiPo batteries to the charge station until you’ve reviewed the steps 

below. Mishandling the batteries and charger may shock the user and damage the equipment.

Be sure to use the LiPo charge station in a well ventilated area and keep the cooling fan clear of 

any obstructions.

7. When the battery is done charging, disconnect the battery in reverse order from how it 

was connected (see steps 2, 3, and 4).

Long-term Storage – To prepare the LiPo battery pack for long-term storage, select the LiPo 

Storage program (see previous steps 1.a and 1.b) instead of the Balance program. The default 

setting is to charge the battery slowly at low amperage to ensure stability during storage. 

IMPORTANT: Never completely drain the battery packs unless discharging them for safe 

disposal. Contact HoneyComb customer support for more information on safe handling and 

disposal practices.
42

AgDrone Maintenance & Inspection

Follow maintenance and inspection schedules to ensure that the AgDrone and its components are 

in top-running form and operate as intended. The AgDrone system includes spares for 

replaceable parts that will wear out over time. Complete the provided inspection checklists to 

identify discrepancies in the system.

Do not access the rear payload bay except to visually inspect the components inside (except 

when replacing the 40-amp fuse). No tampering of these components is allowed and should only 

be serviced by HoneyComb or other HoneyComb-approved facilities.

Spare Parts

Included with the AgDrone System are spares for the following components:

- Winglets

- Propellers

- 40 amp fuses

- Lens covers

- Lens screws

- Motor mount screws

- Plastic Phillips fasteners (long and short)

- Plastic thumb fasteners

Pre-flight Inspection

Review the preflight checklist in the Quick Start Guide. Always perform a visual inspection of 

the aircraft and components before going out for a mission. Clean all surfaces take note of any 

corrosion, structural defects, misalignments, or other cosmetic blemishes that may affect the 

functionality of the AgDrone. 

Light scratches and dents are acceptable for maintaining ideal operation of the AgDrone; but 

further damage should be thoroughly inspected and repaired before being cleared for use. In 

general, ensure that moving parts achieve the proper range of motion with minimal effort and 

operate smoothly. Non-moving parts should be securely fastened – not loose or over-tightened. 

As always, check your surroundings before operating the AgDrone in the field.

50-h Inspection 

Find the 50-h inspection checklist included with the AgDrone System (separate from the

operations manual) and contact HoneyComb for additional checklists as needed. The purpose of 

this 50-h inspection is to visually assess the aircraft and other components for discrepancies and 

identify performance flaws or alterations that have occurred throughout the AgDrone’s lifetime. 

No alterations or electronic calibrations should be performed during this inspection.
