I just got back from a Fabulous February at Lost Hills, CA. I saw Vladimir Sychov make over a dozen flights with his folder. Pretty impressive, I must say. Only bad thing was that it was a 50-50 chance it would fall on its back and do a half loop after the engine quit. The alternate chance was it would flop bottom down and wings deploy for a perfect transition to glide. See attachments.
He has changed from the dual counter rotating props, gear driven arrangement seen on Volar Libremente, to a single direct drive prop and engine. Still goes straight up with a twist.
