5.15.2 Calibrating the Compass

Compass calibration should be done with the model away from electrical

fields and metal objects. The best place to calibrate the compass is

outdoors, at the field where you will be flying.

5.15.2.1 Steps before Calibrating

Before calibrating the compass, make sure that the compass is installed

correctly, and that all equipment you plan to fly with, including cameras,

canopies, etc., are fully installed on the model, and turned on. Adding

equipment later can change the compass calibration!

5.15.2.2 Calibrating using the Stick Menus

To calibrate the compass using the menus, select the “Compass Working ok (if used)?” menu item under the

“Preflight Checklist” menu.

When your model is away from metal objects, click the mode switch once to start the process, which will cause

the menu shown above to appear. Move your radio away from your model and follow these steps:

a) Hold the model horizontally level in front of you, with the GPS arrow pointing directly toward your body

(or directly away from your body).

b) Slowly spin (pirouette) your body around 360 degrees (full circle) while standing in approximately the

same place. This spin should take 6 to 10 seconds.

c) Hold the model vertically, so that the GPS arrow is pointing

straight down toward the ground (or straight up toward

the sky).

d) Slowly spin (pirouette) your body around 360 degrees (full

circle) while standing in approximately the same

place. This spin should take 6 to 10 seconds.

Once these steps are completed, the calibration process is

complete, and the “Preflight Checklist” menu should

automatically reappear.

5.15.2.3 Calibrating using the Mode Switch

For your convenience, you can calibrate the compass without

using your video display, as follows:

 Toggle mode switch 7 times – the LED should flash a fast red/green

 When your model is away from metal objects, toggle the mode switch once more – the red and green

LEDs will blink slowly, indicating you should begin calibration

 Follow steps a) through d) above.

 The LEDs should now return to normal, indicating that the compass calibration is complete

5.15.3 Testing the Compass

5.15.3.1 Load Testing the Compass

If you are not sure that your compass is mounted far enough away from motor/ESC wiring, or other sources of

interference, you can test it by operating your model under load, while it is stationary. First, make sure the

compass is displayed, and note the compass reading. Then, if you can do so safely, run the model at full throttle

with propeller(s) attached, but with the model secured so that it cannot move. If the compass reading changes
