RE: BME Edge?
My Ultra Stick also has 0 degrees right thrust. I find this very nicely done on the 10X but it probably requires that radio to make it work the best (expos, tracerate and mixing are all engaged)
I did not do this on the Carden.. figured why experiment with something that is well proven by Dennis, but everything else has seemed to respond well to it so the next Carden I do may even have zero!
So far my BME edge and USL have zero and it has worked well. I really really hated having to tear off cowls and shims every time to adjust incidence... now I use my radio!
Chip Hyde said that even on his last 40+ plane he used only 1* of right thrust and used the radio to take care of the rest... !
I really like the 1* of LEFT rudder on idle.. it totally eliminates the drift common on low speed inverted flight.. !
It took me some playing and about 30 landings before I was able to get the plane tuned just right.. but it was a lot more fun than adding shims!
