So more progress has been made with the Boca Dune Racer project. Parts were ordered before and most of the parts have arrived. The first thing to arrive was the motor kit that was ordered from MonsterScooterParts.com. The motor kit was the 36V 1000W MY1020 motor with an universal controller and a hand throttle.
