I changed out all of the hardware for 4-40 rods and ball links. I am thinking of even changing the elevator rods for Central Hobbies carbon rods. I have not had a problem with the 4-40 rods though. I fly it as a pattern practice plane, so don't have 3-D throws setup on it. The plane flies great except that snaps are very hard to stop accurately. It likes to over rotate.
