Hello Dick...

Here's a thought: Get a "20-sized" trainer. Then visit Jim Baxter's site www.autogyros.com and Rick Anderson's site, www.gyronuts.com for information on how to build a mast with side-to-side tilting rotor. If you can get a hold of Phil Ploof who lives not far from Tampa, he can give you lots of information on converting a regular free flight trainer type to an autogyro.

The side-to-side tilt functions just like the ailerons on a regular trainer.

The reason for starting with a 20-size trainer is that it will need a .40 size engine to overcome the increased drag that the rotor causes.

Hope this helps.

Bill
