I luuve working on my car, motor, ... and using the comm lathe soldering new brushes, braking a motor or brushes in, ... are just things that belong with RC, I think ...
but on the other hand, a comm lathe will cost you, and so will brushes ...
AND when racing, it is a luxury, not having to care about the regular maintenance of your motor (I use to check the comm and brushes every three runs) or even not having to care about the ideal managment of your batteries, just to be sure to have optimum performance, ...
Take it from me, LiPo and BL are here to stay, and IMHO it is a bit silly to invest in all the other equipment for Ni-.. batteries and brushed motors.
Just my 2 cts.
I did ran my E-Firestorm in a competition last weekend and having troubles with my ESC and motor overheating and other stuff. I just had a new maraba Sidewinder-kit in my toolbox ready to be mounted in my X10.
I simply ripped (actually I did it very gently and with respect ) the ESC-Motor out and replaced by the Sidewinder-kit (Sidewinder ESC + 5700kv BL) .. and had plenty off time later on to concentrate on the setup of the suspension instead of dealing with the motor problems. Very convenient!
... also, that new Sidewinder-kit worked brilliantly. I allready had it set up through the PC-link at home, just in case. Another case of being well prepared
