I think that Big Jim is the most successful and prolifically copied design in modern stunt times, even though few seem to acknowledge it.
I would like to see his 4 stroke design. I would be happy if he would review my new "Alpha".

It is somewhat of a departure from convention.
There also the Zone 2 which is based on a 90% PM wing. I thought about going to my own wing shape, something along the lines of Gordy's Tony but with a bigger flap and a little smaller wing.

There is also the current Hr. Hyde and Dr. Jekyll. The Dr. J has the wing moved forward 5/8" over the Mr. Hyde and uses a low aspect ratio stab and elevator. The Dr. J is almost complete. The Mr. Hyde continues to improve but has been suspect in many ways.
