The Dakota Hawk, was introduced in 1993 with 25+ flying. It can be powered by O-200, 912 & 3300’s. The Corvair would likely be another good candidate for power.

YouTube has a few videos on the aircraft:

I was not able to find any common RC offerings for the Dakota but with some 3D modeling software and time it looks like an easy thing to take on.
