how often should I chang my brushes?
Well I am not new to RC but I am new to electric. So how often should I change the brushes in the motor?

Depends on how serious you are about motor tuning, with my old MVPs I'd change the brushes whenever I cut the commutator, but I was getting a LOT of mileage between cuts. Yeah, truth be told a lot of those brushes I tossed could've been re-used, but to stay in the top of Stock Truck requires you to really keep on top of motor tuning, so why go through all the work of rebuilding a motor just to pass on a new $6 set of brushes?
What really makes a difference is the condition of the commutator. Once that's due for a cut on a comm lathe (ask your local hobby shop), you can decide if there's enough left of the brushes to make them worth cleaning up and re-installing. Typically when they get down around 75-66% of their original length, it's time for new ones.

Ha ha very funny. The problem is that I can't decide to go brushless and lipo or brushed and nimh. so do you have any sugestions?

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 mamba 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
