If you are just messing around alot. Get a can of motor spray, and use that on the shock shafts and in the and around the motor to keep things clean. When you start racing, is when you want to start taking your motors apart and cleaning and re-oiling them, cleaning wheel bearings, etc. Hope this helps
Life moves pretty fast... If you don't stop and look around once and a while...
You could miss it.
