I've been flying a H9 US 120(not light) for about two seasons. The beginning of this season, I've had no less than four CA hinges break at the hinge line. These are the hinges that came with the ARF. They have a litlle slot cut in the middle of them. I've had them break on the elevator, aileron and flap. This plane is by no means overpowered(Zenoah G-23). Just wondering if anyone else has experienced this problem with these particular hinges. Thank goodness for the GP slot machine
