I have the trex se. I keep braking the linkage one the tail its self, the little "L" linkage that make the tail blades pitch. The first time I forgot to take off before i turned my radio on and broke it, second time I dont know how it broke. Anyways its plastic, so i was wandering if anyone knew about a metal one, if there is one plz post the part number and the site where I can find it. Thanks
