To ensure safe and successful flying, familiarize yourself with the safety information 

on this page. Always fly in accordance with your location regulations and these best 

operating practices.

Always fly at least 100 feet (30 m) away from 

people, vehicles, and buildings. Make the safety 

of people and property your first priority!

Always fly below 400 ft (120 m) and within your visual 

line of sight. Don’t let the Aero get too far away from 

you; make sure you can always see its orientation. 

Don’t fly in low light, rain, or other conditions that 

might impede visibility.

Always fly at least 5 miles (8 km) away from airports 

and other areas where pilots operate manned 

aircraft.

Before you fly, determine the boundaries of your safe flying area. If the Aero moves 

outside the designated area or exhibits instability in flight, switch to fly-by-wire mode 

and land the plane manually. Always be ready to regain manual control of the plane 

in the event of an unsafe situation. 

The Aero will not avoid obstacles on its own, including during missions. As the 

operator, it’s your job to recognize and avoid obstructions while flying. When 

planning missions, ensure that the selected altitude is appropriate for all 

geographical features of the area, including terrain.

Location

Spinning propellers can cause serious injury. The safety 

button indicates the status of the motor to help you 

prevent hazardous contact with the Aero’s high-speed 

propeller.

• When the Aero is powered on, the safety 

 button will blink red, indicating that the motor 

 is inactive and the propeller is safe to handle.

• When you’re ready to fly, press and hold the safety 

button until it shows solid red. This indicates that 

the motor is armed and the propeller will spin if the 

throttle stick is raised. To make the propeller safe 

 to handle again, press and hold the safety 

 button until it blinks red.

Locate the two cables inside the electronics compartment marked AILE. Connect these 

cables to the two cables on the wings marked AILE. (Either of the wing cables can 

connect to either of the plane cables; the order doesn’t matter.)

Place the wings over the body of the Aero with the foam 

squares fitted into the matching space in the electronics 

compartment. Make sure not to pinch the AILE cables.

Locate the four large rubber bands. Use the bands to 

secure the wings to the body of the Aero by the four 

orange knobs on the body around the wings. 

Attach two of the bands to the two knobs on one of the 

short sides and opposite knobs on the opposing side.

Repeat on the other short side with the remaining two rubber bands, resulting in two pairs of 

opposing right triangles.

Auto - fly a mission

Fly an autonomous mission. This is the mode that the Aero will use to create the map.

Fly by Wire - assisted manual control

Let the autopilot manage the control surfaces, and navigate based on where you want the Aero 

to fly. Fly-by-wire mode* (FBW) is the easiest way to fly and is the recommended mode for new 

operators.

*ArduPlane mode FBWA 

Return to Launch (RTL) - recall to launch point

Command the plane to circle over the launch point. The Aero will return to the position where it 

acquired GPS lock and enter into a circle pattern at an altitude of 100 meters.

Loiter - circle

Activate GPS-positioned circling; the Aero will enter into a circle pattern with a radius of 60 meters 

at the current altitude. Move the right stick to adjust the position of the circle.

Stabilize - stabilized manual control

Stabilize mode provides manual control with an added autopilot safeguard: Release the right stick 

and the Aero will automatically return to a level flying orientation. Use stabilize mode for the freedom 

of manual control with return-to-level stabilization.

Manual - full manual control

Fly with fine-tuned manual control without autopilot assistance. Manual mode gives you the most 

direct input to the control surfaces, resulting in precise in-flight adjustment. Try manual mode if 

you’re an experienced RC plane operator.

GEAR/MIX selects the set of modes.

 FLAP/GYRO selects the specific mode, either 0, 1, 

or 2.

To select a flight mode:

First, set the GEAR/MIX switch to select a set of modes. Then use the 

FLAP/GYRO switch to 0, 1, or 2 to select a specific mode.

Arming and disarming are important steps that must be completed before 

takeoff and after landing to activate and deactivate the motor, respectively.

The arming and disarming procedures ensure that you can safety start and 

stop the motor without risk of injury.

The Aero’s motor can spin when armed! Do not place your hands in the 

way of the propeller while the safety button is active (solid red).

To arm the motor, press and hold the safety button until it 

displays solid red.

GPS Lock

Auto, RTL, and loiter modes requires GPS lock. When powered, the autopilot will 

automatically search for GPS lock. The position of the Aero when the autopilot acquires 

GPS will be saved as the home position, and used as the coordinates for the launch 

point during RTL. If you plan to use auto, RTL, or loiter modes during your flight, ensure 

that the Aero is located at a suitable launch point when powered, and the autopilot 

acquires GPS lock before takeoff, indicated by a blinking green status LED.

Before arming, check the status LED. The LED will flash blue while 

the Aero acquires GPS; this can take a few minutes. Once you see 

the green LED, the autopilot has acquired GPS lock.

Preflight Checks

Before each flight, perform a physical component check, center of gravity check, and control checks in both manual and stabilize 

modes. If any of the components or assemblies in these checks are not secure, tighten the screws or use CA glue (super glue) to 

secure the components to the foam.

1

Examine the Aero to ensure that all components are secured in flight configuration.

» Check that the wings, tail, and tail boom are fully assembled and securely attached.

» Check that the propeller is secured tightly to the motor.

» Check that the servo rods are secured to the servo horns with the blue clasps.

airspeed sensor

2

Check that the airspeed sensor is secured to the side of the Aero and the 

tube is free from obstructions.

3

With the battery connected and the lid secured, check that the Aero is correctly 

balanced for flight. Hold the Aero with one finger on each of the clear, plastic balancing 

points shown below. These points indicate the Aero’s center of gravity.

If the plane balances on your fingers, then the center of gravity is correct. If 

it won’t balance, adjust the position of the battery until you can balance the 

plane on two fingers as shown below.

Flying the plane without the camera will affect the center of gravity. If you 

choose to fly without the camera, make sure to re-balance the center of 

gravity.
30

Before flying, power and arm the Aero on the ground and complete these checks to verify that the control surfaces respond correctly to the control inputs. Place 

the plane on the ground, and set the mode switches to select manual mode. Move each of the sticks as shown, and check for the corresponding movement of 

the motor or control surfaces.

Auto-takeoff works by sensing the movement of the plane and launching it in that 

direction. Set the Aero to autonomous mode when you’re ready to launch.

Find a launching area with at least 100 feet of clear space in front of you. Face into 

the wind, and hold the body of the Aero in one hand under the center of gravity. Be 

careful not to place your hand in the way of the propeller!

Hold the Aero above your head, run, and throw the plane at an upwards angle. The 

Aero will sense the throw, power the motor, and climb to the altitude specified by 

the takeoff waypoint before starting the survey mission.

Automatic takeoff requires you to configure the takeoff angle during mission planning. See page 18.

!

DO NOT WIND UP YOUR THROW; if the Aero senses any backwards 

momentum it will attempt to launch in that direction. Use only forward 

momentum to throw to Aero!

Automatic Takeoff Manual Takeoff

If you’re new to planes, we recommend having a friend help you launch the 

Aero. Have your friend throw the Aero while you control the controller.

We recommend setting the Aero to fly-by-wire mode for takeoff. Find a 

launching area with at least 100 feet of clear space in front of you. Face 

into the wind, and hold the Aero at the center of gravity. Raise the throttle 

to center position to start the motor. Be careful not to place your hand in 

the way of the propeller!

Hold the Aero above your head, run, and throw the plane at an upwards 

angle.

Once launched, the Aero will require immediate adjustment with the 

controller to navigate away from the ground and up to the desired altitude. 

Pitch up (right stick down) and add any other necessary controls based on 

wind, speed, and terrain.
33

When you’re ready to end your flight, follow these steps to land:

» Fly a circle pattern above your landing area. 

» Come in on a final approach, flying into the wind at 

 an altitude of 20 to 40 meters. 

» When the plane reaches an altitude of 10 meters, set the throttle fully down to turn 

off the motor and glide down 

 on a 15 to 20 degree down-pitch angle. 

» When the plane is one meter above the ground, pitch up (flare) to land the Aero on 

the body of the plane instead of the nose.

Low Battery Failsafe

Environmental conditions can affect power consumption. Use the Mission Planner Flight Data 

display to monitor the voltage of the battery during flight.

If the battery reaches 13.8 V, the Aero will return automatically to circle above the launch point, 

indicated by a blinking yellow status LED and a quick repeating tone.

The Aero is programmed with a set of failsafe behaviors to prevent a crash in the event of a loss 

of one of the data or communication channels required for autonomous flight. Although certain 

failsafe have assigned LED indicators and tones, it is unlikely that you will be able to see these at a 

distance. Monitor the Flight Data screen for failsafe indications. If a failsafe is triggered, the assigned 

behavior will activate. To override the failsafe behavior (RTL in most cases), use the controller to 

regain manual control. 

Regaining Manual Control

To regain manual control during the mission, switch to fly-by-wire mode using the controller. If 

you’re a confident operator, switch to stabilize mode. If you observe instability in the Aero’s flight 

behavior or it the aircraft moves outside your designated safe flying area, switch to RTL. Turning off 

the controller will automatically trigger an RTL and can be used in an emergency situation as a hard 

recall command.

RC Controller Signal Failsafe

Physical obstructions and interference from nearby wireless signals can affect the Aero’s connection with the RC controller. 

If the Aero loses contact with the controller, it will return to the launch point automatically and 

enter into a circle pattern above the launch point, indicated by a blinking yellow status LED.

If the controller failsafe is triggered, wait for the Aero to return to the launch point, then regain 

manual control and either land or restart the mission.

Aerial Imaging Concepts

Understanding key concepts in aerial images can help you understand the mission planning process and create better maps.

Distance-Based Imaging

By default, the Aero captures only the images required to create the map. The autopilot monitors the distance traveled by the Aero and 

sends a command to the camera to capture an image at the distance interval specified by the camera trigger distance parameter (CAM_

TRIGG_DIST). This parameter is set by the Mission Planner Survey Tool during survey configuration by calculating the minimum distance 

between images based on the parameters specified for the survey (altitude, overlap, sidelap). This distance-based imaging allows for more 

precise data collection, resulting in less images and data storage cost.

Once configured, the Survey Tool creates an event at the start of the mission script (after takeoff) to set the camera trigger distance to the 

specified interval and an event at the end of the mission (before landing) to reset the camera trigger distance to 0. Therefore, while on the 

ground and during landing, the camera captures no images because the camera trigger distance is set to 0 m.

Time-Based Imaging

The Aero is also equipped to capture images at a consistent time interval instead of using distance. This function can be useful if you want 

to capture images over an area without planning a mission. This time-based imaging results in more images per area, and therefore more 

processing time and storage cost. See the intervalometer option on page 43 to enable time-based imaging.

Overlap and Sidelap

To capture images for the map, the Aero flies a lawnmower-like pattern in strips across the survey site. The front-to-back overlap between 

sequential images is called overlap; the side overlaps of adjacent pictures in different strips is called sidelap. The overlap and sidelap 

parameters in the Survey Tool (see Advanced Options page 16) determine the distance between images and the number of images to be 

captured based on the projected ground area that each image will cover, called a footprint. The Survey Tool uses a default overlap of 50% 

and a default sidelap of 60%. Increasing overlap and sidelap improves the accuracy of the map while increasing flight time and processing 

time.

In the Survey Tool, Distance between Images shows 

the specified camera trigger distance that will 

be assigned to the mission. You can also see 

the projected image footprint size and the total 

number of images to be captured.

Default overlap: 50%

Default sidelap: 60%
43

3DR EAI

3DR EAI is based on KAP UAV Exposure Control Script v3.1: a great opensource project for kite and UAV aerial photography. 

Start and Stop Script

Ensure the camera is set to P (program) mode before powering the camera. 

Upon startup, 3DR EAI starts automatically and listens for commands from the 

autopilot, indicated by waiting for USB signal. To stop (and re-start) the script, press 

the shutter button. The script will display INTERRUPTED when stopped.

CHDK Menu

The CHDK menu contains all the standard options provided with CHDK. 

To access the CHDK menu, stop the script and select the MENU button.

Script Menu

The script menu allows you to change the parameters associated with the script 

itself, including changing the trigger mode and adjusting exposure. To open the 

script menu, stop the script and select the FUNC. SET button. These parameters 

are configured for the Aero and SX260 and do not require adjustment as part of 

standard operation. 

Trigger Type

This parameter allows you to control how the camera captures images. 

Trigger type defaults to USB for distance-based imaging during mapping 

missions. For time-based imaging, select Interval and specify the length in the 

Shot Interval parameter.

Trigger Type default: USB (mapping)

Image Quality Troubleshooting

If you observe poor image quality during the spot check or if you receive error 

messages during processing, use the settings below to troubleshoot the image 

quality.

Blurry Images

To correct motion blur, adjust the shutter speed using the Target Tv parameter in the 

script menu.

Target Tv (shutter speed) default: 1/1250

To correct moderate motion blur: Set to 1/1600.

To correct severe motion blur: Set to 1/2000.

Overexposure

If the images are overexposed but do not show any motion blur, it can be due to 

flying in extremely bright conditions. To correct this, set the Allow use of ND filter 

parameter to YES in the script menu.

Allow use of ND filter default: No

To correct overexposure: Set to Yes.

Processing Errors

If you receive errors from Pix4Dmapper during processing, increase the overlap and 

sidelap during survey configuration to improve the quality of the image set.

Overlap default: 50%

Sidelap default: 60%

To improve processing: Set overlap to 60% and sidelap to 70%.

Example image: motion blur Script menu: Target Tv

Example image: overexposure Script menu: ND filter

Operational Troubleshooting

No Images Captured

1 If the camera did not capture any images during the mission, first perform a 

 physical inspection on the Aero.

Is the mini-USB cable connected to the camera’s USB port?

Are the AUX OUT 6 pins connected on Pixhawk?

 AUX OUT 6: black (-), red (+), white (s) 

Is the camera battery charged? Unlock the SD card to view the Canon’s 

 battery level indicator.

2 Take a distance-triggered test image on the ground by manually setting 

 the camera trigger distance parameter to 1 m.

Power the Aero and connect to Mission Planner. Select Config/Tuning and 

Full Parameter List. Change the CAM_TRIGG_DIST parameter to 1, and select 

Write Params. Disconnect the Aero from Mission Planner, and carry for a few 

meters to see if the autopilot triggers the camera.
