Hello again Wahid,

Since I haven't had much success with fiberglass hub plates on smaller gyros I'd have to say, I realy don't know if .020" is too thin.
The reason I did not build the Gyrace II with full direct control of the rotor head is simple, there wasn't enough room in the fuselage for all the servos. The Gyrace II was made from an origional Gyrace that at one time had a stub wing and two rotors. I suppose it could be recongigured into full Direct control but there really isn't any need, it flies very good without the cost in dollars and weight to add the pitch control I'm already getting from the elevator.
