I fixed the hinges and it flies better now, but still turns to the left at high speeds. I think due to a twist in the wing. Mine will only flat spin to the left but it will go to the right when inverted. But the plane can not do any other FF manuevers because it is too short. It is very hard to keep the plane going up in a straight line, so I woundn't even think about hovering it even though it has plenty of power with the .46fx and MCP.
