Hi everyone - I have an FC40 and tonight, for the first time, I could not get the copter to move into GPS mode. I had to abandon my plans and come home! When I plugged it into the NAZA control software I found that the right side switch for GPS / ATTI / Failsafe is only going between ATTI and Failsafe, it remains with the central output (ATTI) even though the switch is in the GPS position. So - given that this unit is only a few weeks old do I (1) send it back to the vendor but be without the copter for a week or more, or do I (2) pull open the remote to see what is what and possibly invalidate any warranty on it. Thoughts ? Thanks - Damian.
