    Are you sure you fried it?
    Talk to Cris - there may only be a couple of components that need to be replaced.

    Note these comments from the instructions:
    "Solder the leads of your battery connector to the two pads marked “BATT”. Because of the
    bridge rectifier between the battery and the regulator, the polarity doesn’t matter. You cannot
    connect the battery backwards; it will work exactly the same either way."

    A good rule for rocket experimenters to follow is this: always assume that it will explode.

    Ok back at getting around to this eggfinder. A 2s 7.4v battery with minimum 250ma is recommended. Can you put to big a battery in it? I put a 2s 7.4v 800 ma battery in it. Too big or does that not matter?

    Cris said polarity doesnt matter. You cant hook the battery up backwards.
