Hi Gary,

I’ve had a few gremlins with my rudder trim. I’m happy to report that it seems to have been fixed (fingers crossed). My rudder trim was changing intermittently during or before a flight by ~6%. You can imagine what that does to a pattern plane.... Anyway, after much time, I narrowed the problem down to my Jeti DC-24 transmitter. It was sent back to the factory for repair. They weren’t unable to replicate the fault (so they say) but did reload the firmware and replace a “PC board”. The radio has got about 17 flights on it since repair and the rudder trim is stable. I think they have nailed it.

Cheers,
Jason.
