Motor loosening with RCM Losi 8 mount?

Hrm, I may just try torqueing it a bit then. I'm using 4mm screws and this motor has only been used for 3 race weekends with 2 DNFs. I was also thinking about making the bottom screw a flanged bearing supported screw to give it some support down there. I usually give it a good torque down and use some loctite. I'll trying running it some more and see if I get the same result. I only got 3 tests on it before my brand new servo went bad, so I'm waiting on good weather to try again.
