RE: 90 sized 3D kit?
Top view. All the control surfaces were double beveled. First picture shows dual elevator servos. Later changed out to the large MK elevator bell crank. Took some work but it would deflect 50 degrees. You could possibly lengthen the ailerons, but it flew fine as is. Locked into harriers and elevators. Plane designed by Mike McConville. Saito 125 would be ballistic in it.
