NEU motor broken, how to measure, and locktite in motor screws?

[lincpimp]

Losi TiN coated heax drivers have lasted me very well. Only one broke and that was not with my hand on the handle. I know they are pricey but I have used mine a lot more than most in this hobby ever will.

Ofna had a nice long reach set of hex bits that can be used with a power driver. I have a few Skill brand XO power drivers that have been used daily for at least 5 yrs now. They are small palm sized with an integral battery. Paid 20 bucks each, and with the ofna bits they will do about 95% or more of what you need to do on an rc.
