I have a Raptor 30 V1, JR XP652 radio, JR 450 Gyro, and a JR 4000 tail servo. Today I flew 3 tanks of fuel, loops rolls 540 stall turns in idle up mode. on the last tank I was coming in to check fuel level when I flipped the switch for normal mode I had no tail control. It was locked in one position which made for a hairy landing but i got it down ok! When I checked, the tail servo was locked. When I turned the receiver power off and turned it back on I got full control of the tail again and flew half a tank hovering just to make sure it did not happen again. The only thing I thought it could be is the Gyro. everything checked out ok.
So my question is, dose anyone have any info on this problem with this JR 450 Gyro? And what if any were the fixes?
Thank, Terry...
