I have the same trainer. It is my first plane and I think it's great. Built like a tank.

I actually came across a AMA 2005 magazine with instructions on how to install two aileron servos. I may add them because I want to play around with flapperons.

But one servo has worked well so far and I've been told that I fly very hard and aggressive. Rolls are pretty slow even with dual rates on.

I'll post that article early next week.
