:? my saito 91 muffler / exhaust pipe (curved) vibrates loose about every 5 or 6 flights. Yes, prop is balanced, yes I clean the threads each time. I've tried locktite red & blue, even tried JB weld on threads, still comes loose. The straight exh pipe that comes with engine won't keep muffler inside cowl, so I use the curved 45 exh pipe, with the newer angled muffler. Got any ideas :?:
