We finally got a test run in with the completed brushless system. Unfortunately we didn't have any banebots pinion gears so tried using a hobbyking version. Unfortunately it wasn't the right pitch and left a lot of slop in the gearboxes resulting in a loud, high pitched whine while running the bot. The bot was still driveable, and so we tried the test we're all been waiting for a brush vs brushless push off. The brushless had alot of power, and seemed to have better reaction speed than the brushed system. The brushless system was slower than expected and still lost some push offs vs the brushed system. Overall we concluded a different, lower KV motor, would have been a better choice. Heres some specs on the brushed set up.
