Hi all it's been a while. I can't seem to keep muffler tight on my MA whiplash 700. Zenoah engine and 4000-12 muffler. The heli also tilt's to right in flight. It is two piece manifold and muffler and sticks out from frame. I think that and the weight might be the cause that not sure. I have tried thread lock, permatex gasket exhaust no help. have not used lock washers maybe give that a try. I ordered a one piece muffler that bolts close to frame like a nitro. Any brain farts would be greatly appreciated.
