Muffler keeps coming loose
I have a U.S. 41CC engine I put on a Stinger. It flys great, but the muffler keeps coming loose. I tried the blue locktite, then the red locktite, no luck. After 30 minutes of flying, the muffler is loose again. I have tried 4 times now. I have cleaned everything before applying the locktite.I also use locking washers. I have used the stock gasket, and without. I am using a GP isolation mount, and have to be able to remove the muffler to use the mount. I am thinking of buying a b&b muffler, to replace the stock one. I am guessing the muffler might be damaged (crushed) where the bolts tighten. If anyone has any idea's how to stop this, please post or email me.
