I've been wondering for a while if it has something to do with the tire size so after your mentioned the Great Lakes Biplanes didn't do it I looked at both tire sized.Is this a problem with the brakes??? I get the same "glued in place" aircraft behavior when I hold full down elevator and apply throttle, (that I expect) as to when the aircraft sticks after applying and releasing the brakes during taxi maneuvers.
Your biplanes that I fly do not have brakes and they taxi perfectly.
Great Lakes Biplane Tire Size Main Gear Tire Size
T-28 Trojan Nose Tire Size
T-28 Trojan Wing Tire Size
I don't know if that's an issue but the tire size on the Biplane is quite a bit larger. I think I'll do a test build with larger tires and see what happens. Of course the brakes might be an issue too but often when the plane is first loaded it's stuck, so no brakes applied yet. (unless the problem is there are brakes in the physics even if never applied)
