Will the controller's boost function work with a reglar bit or a zipzap. My Zip don't turn right but the wires look fine so I think its controller. I want to possibly buy the LXX booster+ Perfection from toy east but dunno if its worth it just for controller, bodies & motors for $12 + a monster shipping rate. I need your opinions.

Edit: Where is the best place to get bits cheap (Hobbylink Japan type of prices) with good shipping rates & booster car sets in America?
