The brushless motor is going to run more efficient than the brushed motor.

Keep in mind that your runtimes will most likely drop when racing due to the constant current draw.

The Novak HV boasts a 20% longer runtime so you would probably be looking at up to 18 minute runtimes depending on your power source.

Mike, correct me if I'm wrong but the xl1200 on 15 cells would run at 21600 RPM. So, in order to compensate for the slower rotating motor you would need to gear the transmission higher. In gearing the truck higher, won't you increase your current draw (AMPs) in turn lowering your efficincey/runtime?
