RE: Groovy 3D 90.. Promising
Have the 50 version, w/ a Saito 82 (plenty of power). Good airplane, although it shows its age quickly. The plane looks like it's been through years of abuse and its only got one season on it. The stock landing gear and mount were a joke. The angle of the gear looks cool, but it rips the plate out with even fast taxiing on a grass field. Eventually rebuilt the area and used UCD gear, no worries. The wing tube bent after a lot of hard snaps, resulting in a lot of dihedral and coupling. Sort of got it straight.
It's not a 3D airplane. It will harrier with full elevator and a rearward CG, do a nice harrier roll, and it does some great torque rolls. But what sets 3D airplanes apart, waterfalls, walls, blenders, are out of the question. If the elevator were twice as big then it would be a candidate, but then they'd probably have to redesign that split pushrod thing.
Great pattern type precision. Plenty of lateral lift, coupling was minimal (just a little roll coupling) until I bent the tube.
