I had used little screws for my endbell on my 36-60-2000 in my E-revo. Unfortunately eventually one did break out the motor can. I probably could have had the hole a little further away from the edge. But it was caused from a 20 foot, double backflip rear dive . Sane people should be alright. I just electrical taped it after that, the 1 screw and tape held out.
