I don't fly them myself, but know a lot of the main gyro experts including some named above. There does seem to be a consensus on the RAF 2000 amongst those whose judgment I'd trust that it is a very pretty, very comfortable aircraft which is very poorly designed and has severely deficient handling qualities.
Certainly the only criticisms I've ever heard of Roger Savage is that some people didn't get along with him, not of anything to do with his flying, instruction or professionalism.
I confess if I wasn't so busy with the stuff I'm busy with, the idea of getting involved with gyroplane design and ops, and perhaps trying to help get the fatal accident rate up from the current 1 per 8,000 hrs to somewhere around the 1 per 50,000 hrs (CAP 701) for microlights would be a worthwhile challenge.
