I just completed my dual cell mod but the stupid thing will only go backwards. Kinda annoying since I've been workin on it for over a week. Anyways, anybody have a similar problem or know what's goin on? Everything seems to be soldered up perfectly and I think I wired everything to the right place. The white "B" wire is connected to the back of the motor and the blue "F" wire is connected to the casing of the motor. Please help as I wanna get this bit runnin for once in it's life!
