Rotaryphile and Ben,

Thanks. This has been very helpful in understanding the flight characteristics. I made two more test flights today with a slightly more throw (different horn with clevis closer to the hinge line) and no aileron differential. Without differential and with current throw the adverse yaw is … well very uncomfortable. Earlier tests with no differential must have been with less aileron throw. Incidentally the CG is 1/4 to 3/8” forward for a higher sink rate that is preferred.
