RE: It wants to fly backwards.
Sincraft,
If worse comes to worse, dump the Enya engine on E-bay and buy yourself an OS! I'm a newbie and had all sorts of problems with an MDS .40, low speed needle had a mind of its own and I got very proficient with the deadstick landings. (I was better with dead-sticks then with powered landings!) Finally installed an OS LA40 and that damn things purrs like a kitten. I just wish my flying skills were purring as nicely as my engine!
