Foos,

I have to agree with Kmot, your plane looks a little tail heavy to me as well. Try putting the bubble level on the horizontal stab when you balance it. With regards to your differential aileron comment, you are right. There isn't alot of difference in the amount of throw. I wouldn't worry about using differential aileron on the plane. Besides, you would have to move your linkages to accomplish it since your radio is not a computer radio.

Fly safe and have fun!!
