Ben,
Sharp spotting. Yah...lesson learned...on the Airwild site there is a dialog regarding HiTec servos that don't have a 'cross' on the servo output shaft; for those, Airwild recommends the gold arms. My HiTecs didn't have the cross but the gold arms are definitely not the right choice - the splines are too wide. I tried one of the red arms that I had on hand - perfect fit. New (red) arms are on order. I'm smarter (again).

I tried one of the red arms on one an old 5945 that I have, but it wouldn't work. Futaba arms slips right on with a little force though.
