How to configure a contact sensor in ArduCopter?

Because I have had difficulties in having the motor turn off on landing with my SingleCopter, I want to make a simple contact switch and put it on the bottom of one of the landing gear legs.

When the machine touches down, the switch makes contact and the signal tells the auotpilot to turn off the motor.

Does Arducopter with a Pixracer have this kind of capability? Maybe use the safety switch?



So how are you going to arm the motor in the first place?

Don’t know yet. Still looking for a solution to being able to turn off the motor when the copter lands.

You could have it active only in land mode.
