    To be honest mate it sounds quite dangerous what your doing. By-passing manufacturer placed things like speed controllers is not advisable and anyone who could tell you how to do it will be worried about being liable if they give you any advice. I'd find something a bit more simple if I were you, there's loads of other interesting avenues out there :wink:

    Not enough information.
    Without a controler to ramp up the power it is likely to just flip over.
    I would look into repairing the fried controller.
