RE: GP Super Stearman
Speaking of ground handling, I have the Great Planes PT 17 version, I electrified it with a 160 size electric motor, it flies very well but is an absolute horror to take off(paved runway not grass). Considering using a gyro on the rudder, moved from grass run ways in NJ to Arizona(no grass here). This plane defies logic will ground loop in a heart beat.
