Ramrod, I am in the process (fumbling) of trying to figure out how to up scale a scratch built UCD. So far I think I have to go 38% to accomodate a 3W 24 gasser. That should put me at 1420 sq. in. wing area resulting in an app. 90" wing and 106" fuse length. Do you think I could hook up with Greg via E-mail so I could pick his brain? Thanks, Joe
