RE: GP Super Decathlon
That landing gear is pretty flimsy. I bought a fiberglass gear that pretty much fit perfect with no mods in the old mount. I think it was the dubro fiberglass gear. I've seen them at all the hobby shops around here. Pretty common. If you are new, I wouldnt do a spin for a while. At least until your good at spin recovery. This plane will do an evil snap if you have too much elevator and go into the most beautiful spin you ever saw, right into the ground. I managed to recover mine right as it went behind the tree line. My motto is "Never give up until you hear it the ground". I gave it a touch of up elevator and up it popped from behind the trees. Had to do a clean out in the porta potty after that one.
