Steve, thanks for the kind words. I am a better wrench than a driver. The fan runs off of the rx. Regarding the brakes, I just feel more comfortable with the mechanical brakes, you can adjust brake bias, there is less wear and tear on the gears/motor/esc. When you use motor brake only you bascially lock the spur gear, but the diff will then decide how much brake to give to the front/rear depending on traction. Too iffy for me. Don't get me wrong, motor brakes work fine, it makes the buggy lighter and there are less things that can go wrong.
