Which can be life or death for a FPV plane.
Hi HKM, excellent idea to create this thread.
I read and can't agree with the above.
IMHO , Using a rc rx with fail safe is a MUST in FPV, particularly when we want to activate the RTL feature of the Ap to bring our model closer in order to regain control over it again.
Of course, this is true with the help of coPilot (or the ardiIMU I think).
I've been there, the Ap save the day a multiple of times
I don't own the arduIMU but I'll keep an eye (or two) over this thread
