Thanks for the info.... but I need more clarity. If I build a 4 seater gyro with twin engines and still fly it as E-AB with a Private rating the FAA doesnt care as I am flying solo. Now, if I go ahead and carry passengers in it but have no multi engine rating as required in a fixed wing. What am I doing to get in trouble with the authorities?You can build a twelve engine engine gyro if you like, and register it as Experimental Amateur Built. It won't qualify for sport pilot operations, but if you have a Private rating or higher, you can fly it.
For rotorcraft, the number of engines is irrelevant to pilot licensing. For example, you can fly a helicopter with 1, 2, or 3 engines all on the same rating. There is no "multi" rating corresponding to that for airplanes.
You think those are widely spaced ? They look about as close to the centerline as you can get to me. They are much closer than any GA twin I can think of. Look at the Velocity Twin - it has no VMC roll at all. Even better if these are counter rotating I would think.I certainly would not want to fly a widely spaced, twin engine gyro like that with "one turning" and the "other windmilling" right at take off.
What would be the Vmca (minimum control airspeed, in the air), Vmcg (minimum control speed on the ground), and Vmcl (minimum control airspeed when landing)?
What ever happened to Jack Craft's twin engine Gyro 200?
