Hello,
We are flying a Cinestar 8 with Wookong M with futaba 14sg. In one of the flights we were on the beach and we had to film close to(~100 meters) an military station with a radar and different antennas. We made range check and the range was shorter than usual but adequate and we decided to fly. Everything was ok for about 20 minutes and I was going to land when I suddenly lost control. The copter not further than 30 meters away and was just staying in one place with no reaction on my sticks commands. Switching to Attitude fixed the problem and we land succesufully. Looking at the log we noticed that the control mode level has switched from 0 to 1 where 0 is GPS Atti, 6 is Atti and 3 is Manual. In between should be Failsafe(if we understand correctly the log), but if the copter entry in Failsafe it should gain height and go to home point and no such thing happen for atleast 9 seconds until I realized the problem and switched to Attitude. Attached is a picture of the log.
Is it possible this to happen due to interference or maybe some error in transmitter or wookong?
