My slipper clutch keeps loosening up on me, I have already replaced the locknut and it only lasted 2 tanks. It seems like it gets too hot and softens up the nylon locking part of the nut. I didn't replace it with the traxxas locknut, instead I used a generic nylon locknut. Do you think the stock one has some "high temp" locking nylon? I don't think locktite will work being as it still has to be adjustable, any suggestions would be appreciated.
