RE: Stripped RPM wheel hexes... Why?
I had this same problem on my E-Revo. I kept stripping one wheel and always thought I had the nuts tight enough. Each time it would strip the wheel would become loose. After 2 wheels I started using Blue Loctite and really screwing them down. Problem went away without changing to 17MM hubs. Not sure if it'll work for you but I haven't stripped a wheel in 4 months.
