Im interested in learning what the largest kitted or ARF Autogyro might be. I saw the radial engine on the front of the gyro in the Arizona ad and was wondering if it were a real radial engine or a dummy. I have an OS 5 cyl sirius radial and a large autogyro might be the place to use it.

Thanks,

It's a fake radial. If I had a five cylinder radial I wouldn't risk it on an autogyro, if you want to play with autogyros start with a .40, it's cheaper.
