smok - Thanks for the comments and advice. As it's set up now, the elevator has very little throw on low rate and at least 70% expo. It snaps at way below half throttle and even when pulling elevator in slowly and smoothly. I think you may be right about the CG. I'm going to move it to the aft limit recommended by Fliton and see what happens.

I don't know where people got the idea that the Inspire is a 3D trainer. I don't know jack about 3D but this looks like a very capable airplane. The wing is triple tapered and the overall lines and moments of the model look excellent.
