I have finaly finished my first gyro. It was converted from a fixed wing trainer. I scratch built the pylon and hub with help from www.autogyro.com, and people and various posts from this web site.
It is powered by a Meco 46, has a rotor span of 72 inches, with DC control, 3 bladed hinged rotor hub limited to 30 degrees up flap and 0 degrees down flap. I haven't flown it yet, been having 30+ mph winds. Used 1/16 bass wood under the trailing edge of the Aerobalsa blades for 2 degrees negative pitch. Thanks for every ones help.

Tye.
