Greetings, all,
In re the left/right turning oddness, as an experienced heli and fixed wing pilot, I suggest that, in addition to the precession (Gyroscopic effect from the rotor, causing force to be shifted 90' in the direction of rotation) there might be an added effect from the precession of the thrust prop as well.

I am new to the autogyro thing, but have wanted one all my life, and finally acquired a 2D made by autos of Az.
I got it second or third hand, and no docs. Any input about the setup and behaviour of this model would be GREATLY appreciated!!
I am thrilled to see a group of folks with similar interest!!!
