I just came in from 3 short test flights with 3 different settings for the GOV gain. I tried 18-20-16 in that order - and, OH BOY did the JR sound different. All the flights up til now, the bird was flying on the wrong gain settings.
The lower I went, the smoother the sound. On 16 I noticed the tail started to fall behind. So I think I will land on 17, 18 or 19. I'll need more test flights, and a good analysis of the Castle log first.
Hopefully I will get everything ready for tomorrow so I can make a video.
