    Use one of the long can 600 on 6-8 cells and it will rock. Use a 700 and 12-16cells and it will sink like a rock!:D

    it really depends on what you plan on doing with the hull,for speed
    a 540 modified ...ex:13 turn double.. on 7 cells with a good set up
    will give you good overall speed & reliability,& fair runtime.[8D]
