Steve: According to Type Certificate Data Sheet A-787, the M-10 up aileron should go up 24 to 28 degrees and the down aileron should go down 9 to 11 degrees. This is part of the design. Sounds to me like yours may be normal. The purpose of this is to reduce adverse yaw when in a banked turn. The Type Certificate Data Sheet A-787 applies to ERCO 415-D, E, G, Forney F-1, F-1A, Alon A-2, A2-A and the M-10. Because of this neat design, I can make steep turns in my F-1A with my feet off the pedals and on the floor with the ball centered. However, the up and down limits may vary slightly between models. The F-1A (also the 415-E,G, F-1, A-2 and A2-A) for example, is up 40 degrees and down 10 degrees. The 415-D is up 40.5 and down 9.5 degrees.
