You are a Rockstar!!! Thanks a ton, despite your not being familiar with my radio, I think you got it but I need to check when I get home.
I had the up and downside set at +100/-100, and was having the problem, but I will play with the offset number and see if that does it.
Thanks also for correcting the order of the mix- rud to throttles
You made a happy guy! I will read up on differential thrust; thank you so much!
