    I have oportunity to get a used Impulse 31 (I hope) With a twin no torque effect, the sound of 2 motors is music and those outrunner are incredible for a low price. Does somebody run an Impulse 31 with 6S battery?

    Ran minie with 6s but forgot that a UL-1 2030kv motor can't handle 22.4 volts. oops burned up the motor. ( 44400 rpm )
    but I have also ran it with a 1090 kv on 6s, was in the high 40s.
    I am also thinking about a BJ 1500 kv motor in the impulse, and run it on 5s-6s.

    Gonna be hard to use those motors when you have them in the swap shop. How's the MMP going. 6 months later now. Drill a hole yet?

    not sure if you know this alfa but this hull has an offset prop shaft to counteract the torque effect...not somthing you see every day on a RTR boat!
