- zip tie and connect speed controller
- Put the screws in a center piece and attach legs putting the gimbled leg in the center
- use shorter 1 1/4 inch screw on inside for gimbled leg - attach so that the motors face down and the wires are accesable - photo7
- connect wires together in middle using solder and speaker wire
- pigtail all negative and positive from the speed controllers - cut and strip black and red wires - cut and strip speaker wire - cut shrink wrap and solder wire red to red black to black - photo8 - lighter for shrink wrap - combine all neg and wire to neg for final wire - do the same for pos - don't forget skrink wrap(large) - Extend all control wires - only the white wire from the two legs without the gimble - all three from the gimble - leave about 4 inches past the hole through the center section to the top - takes a while; don't forget the shrink wrap - attach the top plate - I messed up the side I soldered the large wires and had to flip the legs to make the bottom plate the top - photo11 - photo10
