The Outcast owners manual states to run-in the motor prior to first use. It's listed in the first part of the manual under the ! section. This is how it's worded in the manual: Always ‘Run-in’ your vehicles’ brushed motor prior to use. ARRMA recommend supporting the vehicle with the drive wheels clear of the ground and run it at constant, low to half throttle for at least three full battery packs. Is this really necessary with a brushless motor? I've never heard of such a thing.
