# Non Manual Mode Overview

To prevent the accidental switching of the mode swi tch to manual mode, the manual mode has been removed from the AgEagle and hand-held controller. Also it is no longer necessary to click the mode switch 3 times to land or 4 times to hand over cont rol to the computer. The three position mode switch now logically progre sses from the bottom to the top positions. The three positions are: Bottom = Launch (assisted flight) Middle = Automatic /return to home Top = Land Differences of the non-manual mode switch:

• Because there is no manual control and total contro l is done by the autopilot, the control surfaces will no longer move until GPS lock is accomplished by the autopilot. This reduces the potential of launching before GPS lock is accomplished.
TIPS:

• It is a good idea to confirm that these modes are a ctive in your AgEagle after

converting to the non-manual configuration. To do this, connect your AgEagle to the ground control program on the laptop compute r. With the AgEagle on the ground, flip the mode switch to the appropriate three positions while observing on the instructions on the top right hand side of the ground control screen. Just check to make sure that when you flip the mode switch down, that MANUAL does not appear.

• Consider placing a label on the bottom of your hand held transmitter with the above instructions on it.

• When installing the non-manual mode firmware for th e first time, it is important that you observe the desired mode on the screen on the ground control to confirm that the desired mode is displayed when mo ving the mode switch.

# Preparing to capture aerial images

1. 

### Set Home/Landing Position and checking failsafe Switch 5 times with right stick

• 

### Set plane down in the spot and direction you wish t o land. This would typically be with the nose of the plane pointing into the win d. Crosswind landings can be done but NEVER with the wind (down wind)

• 

### Check to make sure approach pattern is clear of obs tacles. If not see changing approach direction.

• 

### Power up transmitter. Power up plane and wait 30 se conds for the GPS to acquire satellite data.

• 

### Hold the right stick in the lower left-hand corner flip the switch 5
times. (Beginning in the lower position move the switch to the mid position and back down = 1 time).

• 

### Elevons will acknowledge your request and run a dia gnostic test. Within 15 seconds elevons will either confirm by moving up an d down together or elevons will move up and down opposite each other meaning s ystems are NOT ok to fly.

• 

### If elevons move opposite each other wait 30 seconds and then hold stick to lower left corner and flip switch 5 times again. Th is typically happens if GPS has not had time to lock on yet.

• 

### When elevons respond by moving up and down together , home has been set.

• 

### Check failsafe

• 

### With the AgEagle still turned on, move the mode swi tch to the bottom position (launch/assisted flight) on the hand held. Hold the right stick in the bottom right corner. While holding the right s tick there, turn off the transmitter. (This simply puts the elevons at an u nusual position allowing you to see that they return to normal position if t he fail-safe functions properly.

• 

### The elevons should move back to normal position whe n the transmitter is turned off.

• 

### Pick the plane up and rotate it like it would be ro lling in a turn. Watch the elevons to ensure that they are moving when the AgEagle is rotated. If the elevons are responsive when the ha ndheld is turned off, the fail safe is set

• 

### Power off plane. Power off transmitter.

• 

### Confirm on laptop that home has been set and is in the location that you set home.

• 

### Launcher set up

• 

### ALWAYS FACE LAUNCHER INTO THE WIND

• 

### Slide the two sections together

• 

### Attach the legs and secure with pins.

• 

### Inspect all fasteners including launch arms. Arms must swing freely when not under tension, but should not be overly loose.• 

### Carriage should move easily roll from the top to th e bottom on the guide rail. If not, determine cause and correct.

• 

### Inspect steel cable for cuts or signs of fraying.

• 

### Attach stretch tubing by holding onto the pulley ri ng while at the same time stretching the tube and attach the stretch tube to the pulley ring

• 

### The number of tubes is related to wind velocity. I n mild winds (0-12 MPH) attach

• 

### Pre-launch Sequence - Switch 3 times with right stick set launch di rection, zero airspeed, and set ground level.

• 

### Set plane on launcher.

• 

### Power up transmitter. Power up plane

• 

### Hold the right stick in the lower left-hand corner and flip switch 3 times.

• 

### Elevons will acknowledge your request and run a dia gnostic test. Within 15 seconds elevons will either confirm by moving up an d down together or elevons will move up and down opposite each other m eaning systems are
NOT ok to fly.

• 

### If the conditions are windy, after you flip the mod e switch three times, hold your finger over the pitot tubes (front and under t he wing) to prevent wind from entering. Hold your finger over the tubes unt il you get the second acknowledgment of the elevons moving. Release your fingers when the elevons cease moving.

• 

### If elevons move opposite each other wait 30 seconds and then hold stick to lower left corner and flip switch 3 times again. Th is typically happens if GPS has not had time to lock on yet. Also, repeat holding y our fingers over the pitot tubes as before.

• 

### When elevons respond by moving up and down together Pre-Launch is set.

• 

### Allow the AgEagle to measure the wind for fifteen s econds and move switch to the middle / launch position and move right stick l eft and right and note that the elevons move appropriately.

• 

### After the three clicks preflight has been started, release the right stick and DO
NOT MOVE ANY SWITCH OR STICK UNTIL AFTER THE ELEVON S HAVE MOVED THE SECOND TIME! If the sticks are moved when the calibration sequence is started the system can be caused to go out of calib ration. This is CRITICAL!

2. 

### Preflight check

• 

### Ground control checks

• 

### No big X should be displayed on the ground control screen indicating
NO GPS

• 

### The small green bar in the top left hand corner sho uld be filled with green, not just outlined. A filled green bar indic ates a good GPS lock on the AgEagle

• 

### Check that you have live telemetry with the ground computer
1. 

### Bottom left hand side of screen should say “Receivi ng data from plane”2. 

### Bottom right hand side of screen should show number s counting

up

• 

### Confirm home / landing position is in the correct l ocation

• 

### Check switch is in the bottom position

• 

### Check pitot tube is clear and vent tube

• 

### Check that elevons respond to right stick moved lef t and right

• 

### Check that launcher hammer is pulled securely forwa rd. No tubes are tangled or cable is twisted.

• 

### Clear everyone from the launch area
3. Camera

• Set light for camera

• Install camera in AgEagle

• Turn on camera
4. 

### Pre-launch quick check

• 

### Home set

• 

### Camera installed, on and operating

• 

### batteries fully charged

• 

### Radio modem communicating with computer

5. 

### Launch sequence/Laptop control

• 

### Check that the mode switch is in the lower position

• 

### Remove safety pin.

• 

### Move left stick (throttle) all the way up allowing the motor to reach full speed which usually takes 10-15 seconds

• 

### Step on launcher release. And watch plane climb out to altitude

• 

### When plane reaches altitude flip switch to the midd le position (this will tell plane to circle over the home spot)

• 

### Check to see that laptop tab on the upper right cor ner of the screen is flashing. If flashing check box to hand over control of aircraft to laptop. If not flip the mode switch all the way down and back up to the middle p osition.

• 

### Right click anywhere on map and select fly to first waypoint.

6. 

### Bring plane back to home spot and circle

• 

### Move the mode switch all the way down then back to the middle position

• 

### It is a good idea to observe on the ground control (top right hand corner of the screen) that you are in the desired mode

7. 

### Resume a Mission Flip the mode down an d back to middle

• 

### Check to see that laptop tab is flashing on ground control. If flashing check box to hand over control of aircraft to laptop. If not flip the mode switch all the way down and back to the middle then click the LAPTOP c heck box in the upper right hand corner.

• 

### Select the waypoint you wish fly to.

• 

### Right click anywhere on map and select fly to selec ted waypoint.

8. 

### Landing sequence Move the mode switch to the t op position

• 

### Confirm the AgEagle is in landing mode by observing the LAND mode indicated in the top right hand corner of ground control.• 

### Watch plane circle down wind and turn back into win d on its final approach

• 

### When plane is on its final approach and nearing the landing spot prepare to cut throttle

• 

### As plane is nearing landing spot and is approximate ly 20 ft above the ground cut throttle to zero. (move left stick all the way down ) and watch plane float to the ground. 

# When Things Go Wrong

1. **Locating a downed plane**

• **Coordinates from PC**

• **If the wing lands somewhere you did not intended f or it to land,**  **you can use the last reported position on the groun d control to find**  **it. In this case do NOT shut off the ground contro l. Look for the**  **AgEagle on the ground control, it should be reporti ng its position**  **via the radio link. Simply move the mouse over the top of the**  **outline of the AgEagle displayed on the screen (the large red**  **triangle). Make note of the coordinates of its loc ation and enter**  **them into a handheld device. Use the handheld GPS device to**  **locate the AgEagle.**

• **It is important to not turn off the PC so that if t he AgEagle is**  **damaged and not able to report its position, you wi ll want to make**  **note of where the AgEagle was last reported. This is most likely**  **near where the AgEagle is located at.**

• **RSS from hand held**

• **The Taranis handheld transmitter can be used like a reverse**  **direction finder to locate a downed AgEagle. To lo cate a downed**  **AgEalge with the handheld radio, point the antenna out on the**  **Taranis radio. Hold the PAGE button down to displa y the RSS**  **(Radio Signal Strength) bar graph. The bar graph s hows the**  **signal strength of the radio signal emanating from the**  **AgEagle. Because the tip of the antenna is the poo rest receptor**  **of radio signals while the side of the antenna is t he best, when the**  **antenna of the handheld is pointed directly towards the AgEagle,**  **the RSS bar graph will indicate a weak signal. How ever, when the**  **transmitter is turned where the side of the antenna is facing the**  **AgEagle, the RSS bar graph will be the highest. So , in a reverse**  **sense, this method can be used to locate a downed A gEagle.** 
2. **Loss of power in handheld**

• **Landing from the ground control - If your hand held radio fails and you**  **want to land, simply go to the ground control PC. On the top right hand**  **side of the screen, select from the pull down menu “Auto Land Plane.”** 

• **(details are pending)**
3. **Loss of power to computer**

• **(details are pending)**
4. **When you forget to set home**

• **If you forget to tell the AgEagle where to land it will either land where you**  **last told it to land if that location was within a 1⁄2 mile of where you**  **powered it up again, or if the last landing locatio n you programed the**  **AgEagle to land was more than a 1⁄2 mile it will try to land at the location** **you powered it up and in the direction you had the nose pointed at that**  **time.**

• **So if the AgEagle seeks to land where you powered i t up, it is best to flip**  **the mode switch three times and go ahead and initia te an auto**  **landing. Instead of allowing the AgEagle to land w here you powered it**  **up, assuming that the area is not ideal, just allow the AgEagle to head**  **toward the sight but cut the power with the throttl e prior to reaching the**  **intended location.** 

### 9. Changing Approach Direction for landing site

· This is done when setting home/landing spot

· Set plane down in the spot and direction you wish t o land. This would typically be with the nose of the plane pointing into the wind. Crosswind landings can be done but NEVER with the wind (down wind)

· Stand with nose of plane facing you

· Survey the area to your right. If obstacles are in this area you must chan ge approach direction to your left

· Power up transmitter Power up plane

· Hold the right stick in the lower left-hand corner and flip switch 5 times

· As soon as elevons acknowledge your request, but be fore they confirm by moving up and down together. Shift tail of plane to your left and nose of plane to your right.

· When elevons confirm by moving up and down together the approach pattern will be set to your left. Left hand approach will remain until hom e is set again and then will revert back to default of right hand approach. Installing the AgEagle / Uthere Ground Control and testing

• 

### Before beginning installation of the AgEagle ground control software, turn off ALL virus scanning software on your computer

• 

### If you have previously installed a prior version of the ground control software, first uninstall it by using the windows uninstaller

• 

### Download the latest version of the ground control f rom: http://uthere.com/ageagle/download

username: ageagle password: tractortuff

• 

### After the ground control is installed, restart the computer

• 

### Plug in the ground base antenna with the USB cable while your computer is attached to the Internet. Once you plug in the ant enna transceiver, your computer should automatically download necessary dr ivers. Be sure your computer is set to automatically install new driver s. Otherwize it will not work. Troubleshooting USB ground antenna installation: **I have found that two issues can cause big problems in preventing your computer from automatically**  **installing drivers when the USB is plugged into the antenna and computer.** 

1. **The "automatic detection of new hardware and instal lation in windows" is**  **turned off.** 2. **Virus software conflicts with the automatic detecti on and installation of new**  **hardware and drivers. The driver for the ground transceiver will normally**  **download automatically once the transceiver USB cable is plugged in, but if not, here's a link to**  **download the driver: http://www.ftdichip.com/Drivers/VCP.htm** **Or click here for an executable:**

  Note: The AgEagle aircraft should not be powere**  **d when the transceiver is plugged in for the first time /**  **installing firmware. Packets coming in from the Rub y transceiver during install might confuse windows.** 



### Creating a flight plan

• 

### (to be created) 

# Camera set up

SD Card

CAUTION! – Do NOT FORMAT the SD card! Formatting i t will destroy the special coding imbedded in it, which causes the camera to do speci al functions. It is important that the camera be allowed to acqui re GPS signal before you launch the AgEagle. A few extra moments should be allows for the first flight of the day or at a new location for the GPS to get a LOCK on the GPS const ellation.

Canon S100 settings

Initial set up of camera: (AgEagle sets the follow steps on the camera. These steps are documented for your records)

· SD card is especially formatted for use with your c amera

· SD lock = slide to ON

· Shutter speed is set to 1/2000 of a second

· Digital zoom = off

# Nice to know, but not critical

**The meaning of the lines, arrows and colors around the triangle on the ground control**  **The red triangle shows the plane's heading. The colored vectors emanating from the center are:** 

• **actual heading and airspeed: dark red**

• **target heading and airspeed: light red**

• **course and speed over ground: dark green**

• **target course and speed: light green**

• **wind direction and speed: blue The red circle is to give scale to the vectors. It**  **represents the default airspeed of the plane (i.e. 25**  **knots). If a vector length = the radius of that ci rcle, its magnitude / speed is 25 knots.**  **The purple arrow from the center of the scan area s hows the general progression of the scan. Typical**  **ly you'll point that into prevailing wind.**  

# Tips and tricks

• Turning the AgEagle on: Considering the fact that sometime you may forget to set HOME position, consider always pointing the AgEagle into the wind. If you get into this habit - when you forget to set home, the AgEagle will automatica lly land into the wind. Although, it will try to land wherever you may have turned on the AgEagle yo u can simply reduce the throttle to force it to land at your desired location

• Avoiding manned aircraft: If a low flying aircraft enters your operating area, you can avoid it by either leaving in the area where it is at, returnin g it to home or allowing it to land away from home. To allow it to land away from home, simply pull the throttle back and the AgEagle will simply land.

• Calibration panels : The grey panels we have been using had too much ref lectance in the blue band. The target in the attached images was made by painting particle board with Behr exterior flat Italian Olive (S-H-390), available from the Home Depot. The bala nce between NIR, green and blue is close to perfect

• SOS beacon: A new feature being added as of 05/24/ 14 to production systems is the SOS beacon. So, in the event your AgEagle lands in tal l crops and is not easily visible, just flip the S C switch to the up position and an audible beacon wil l sound off SOS.

• Effects of wind on the landing pattern: When the A gEagle is signaled to land by flipping the mode switch up, it begins to measure the wind veloc ity. By knowing the wind velocity the AgEagle determines the altitude it will fly just be fore it lands. So it is important to know that during windy conditions that on the base leg just before landing it flies higher higher than it does under calm conditions. The reason it is impor tant to understand this is that you may find that in a narrow landing area that the AgEage flies over the top of obstacles just before landing. However if you fly the same area and land in the same location / direction under no wind conditions, the landing pattern will be much l ower and may fly into the obstacles that itpreviously had flown over in windy conditions. So be aware of this when you set your landing

area and direction for landing.

• AgEagle flies home early or does not complete the s can pattern: When this occurs it is possible that strong radio interference from another source on the 900 Mhz band is causing interference. When this happens you can fly a sca n pattern by loading a scan pattern into the micro SD card on the autopilot. The results of doi ng this is that when you flip the switch to the middle position, the AgEagle will fly the scan patt ern on the SD card and ignore any signal from the ground control. This can easily be do by savin g the a scan pattern created on the ground control computer and saving it by clicking on Waypo int, create UTWPB file. Remove the micro SD card on from the autopilot, install it in a micr o SD card adaptor into a computer, transfer UTWPB file to the SD card under the “ruby” folder. Reinstall the SD card into the autopilot, check connection with the ground control computer, ensure the red triangle is pointing the direction that the AgEagle is pointing on the groun d. Now, after launch and the mode switch is flipped to the center position the AgEagle will fol low the flight plan on the SD card. Be sure to remove this file when you are done.

• Launches that don’t work: If the AgEagle leaves th e launcher but only goes a few feet then onto the ground, check:

• Do you have fully charged batteries. Undercharged batteries do not produce enough power for good launches.

• Is your propellor on backwards? The writing on the front of the propellor should face toward the front of the plane. There should be no writing on the back side of the prop that faces the back of the plane.

• Is the correct propellor installed? Right diameter and pitch for your motor?

• Did you allow the motor to reach full power before releasing?

• Did you have enough bungees installed? If you are launching with no or little wind, you need more bungees. In no or light wind conditions use 8-9 bungees.

• Are you launching into the wind? Never launch with the wind. Even slight tail winds will cause difficulty.

• Hi altitude and calm winds are both difficult. Be sure you follow all of the above checks for good launches at high altitude and hot weather.

• The AgEagle talks to you with the movement of the e levons. Here is what the movements

mean:

• If elevons wags, OK TO FLY:

• 3 wags: plane is currently more than 30 feet from h ome / landing target.

• 5 wags: plane is less than 30 feet from home / land ing target.

• If elevons wags to left , DO NOT FLY:

• 4 wags: Battery very low **. You probably don't have enough power remaining for a safe flight.** 

• 8 wags: No radio link. **Be sure transmitter is on and bound to receiver (light appears on receiver).** 

• If aileron / rudder wags to right , DO NOT FLY

**.**

• 2 wags: GPS invalid. **First fix may take up to 2 minutes, so you may simply need to try Preflight again. Be sure GPS is**  **clear of wires, antenna pointing up,** 

• 3 wags: Battery somewhat low **. You may just have enough power for a short flight.** 

• 5 wags: Magnetometer distorted **. Be sure that the plane is away from car, tools, watch, etc..** • 6 wags: Preflight never completed because plane nev er stopped moving **. The plane must be absolutely stationary during pr eflight.** 

• 7 wags: Misc. sensor or other issue **. If problem persists.**

• 8 wags: Radio link poor. **Be sure transmitter is on and bound to receiver, and receiver and antenna is clear of wire**  **s, far from video transmitter, and at least a few inches away from sw**  **itching BEC, ESC, and other sources of interference, and antenna wire**  **is not broken.)**

• 9 wags: Sensor orientation **hasn't been set** Software: Agisoft and AgPixel

• Both Agisoft and AgPixel can only be installed on o ne computer at a time.

• If you want to remove either AgPixel or AgiSoft fro m a computer and reinstall it on a new machine, you can do this. HO WEVER, be sure to uninstall it either from the programs uninstaller o r windows uninstaller. By using uninstalling it this way, th e license key will be released allowing the program to be installed on a different machine. Configuring the magnetometer: The procedure: **First, be sure that there are no ferrous or magneti c items in the airframe near the airspeed / magneto**  **meter sensor. A steel screw, control rod, or servo less than an inc**  **h away or a canopy latch magnet less than a foot aw ay will both**  **produce an unacceptable level of distortion. You mi ght use a hand compass to scan the area around the**  **sensor. (Be sure you're not wearing a steel watch or jewelry.)**  **You'll need to tell the AgEagle auto pilot to recor d extra information to SD Flash that can be used fo**  **r configuration of the magnetometer:**  **Insert the SD Flash chp into your PC and open the " ruby" directory.**  **Move the existing ".utms" file outside of the "ruby " directory temporarily.**  **Replace it with the file " calibration_data_recording_settings.utms**  **" (click to download). Insert the SD Flash chip back into the autopilot.**  **Now, take your AgEagle with outside away from large ferrous items (i.e. 20 feet from automobile).**  **Throughout this entire ritual you will hold plane b y the nose, with tail pointed away from you.** 

1. **Face towards magnetic north. Up to about +-20 degre es error is allowed, but preferably you'll have** 
**a compass.** 2. **Keeping the wings level and yourself facing north, dip the tail so that the tail is pointed straight**  **down / nose pointed straight up.** 3. **Smoothly raise the tail until it the tail is pointe d straight up / nose is pointed straight down.**  4. **Face magnetic south and repeat steps 2-3.** 5. **Face magnetic west, with tail of plane pointed to m agnetic west.**  6. **Keeping the fuselage parallel to the ground, rotate the plane so that it is rolled 90 degrees to the**  **right, then smoothly rotate until it is -90 degrees to the left**  7. **Flip the plane upside down and repeat (still facing west).**  **Send the data.utd file that was generated during th is ritual to**  **BretC@AgEAgle.com**

**. You'll soon receive an updated configuration file c**  **ontaining new calibration data. Remove any existing ".utcfg" file**  **from the "ruby" directory and drop in the new .utcf g file that you receive from us..**  **Remove the "calibration_data_recording_settings.utm s" file and put the original .utms file back in the**  **"ruby" directory.** 

# What Not to do!

• Changing the transmitter - Do not make any changes to the Taranis transmitte r. Although it is tempting to push the buttons surrounding the LCD d isplay to explore the inner workings of the device, please do not explore. If you accidently c hange one setting, the results can be very disappointing.• Damaged transmitter - Do not fly if you drop the transmitter until you d o a very careful

preflight. It is possible that if a switch was bro ken when the transmitter was dropped, that a failed launch may result.

• Trim buttons - Do not move the trim switches to make adjustments to the elevons. If it is necessary to recenter the elevons it must me done m echanically by adjusting the push rods. (See adjusting the elevons section) 

# Rigging and set up of systems

• Elevon alignment (coming)

• GPS (coming)

• Airspeed / magnetometer (coming)

• Launcher (coming) 

# Symptoms and solutions:

Below are symptoms and possible solutions

• Weaves back and forward along course:

• Need to calibrate magnetic west

• Magnetometer is not seated flat in the pocket and n ot straight

•

• Comes off the launcher but does not fly:

• Wrong prop?

• Prop on backwards? Numbers should face toward the FRONT of the palne

• Carriage on launcher binding?

• Batteries are not fully charged?

• Elevons are not set with at least 10 degree of wash out (reflex)
