    I've tried 350, 500 watts and finally settled on using 750 watt motors.....problem I can't find a true 750 watt motor, so I use an 800 watt, those are available.

    What speed results with 800 Watts?

    Have you considered using a pair of 400 Watt motors?

    I have no speedo, but would guess at least 20mph. probably more....2 motors equals too many batteries, and LiPo's are to expensive

    A pair of 400 Watt motors using the same batteries as a 800 Watt motor will produce equal power.

    (2 - 40 Watt light bulbs = 1 - 80 Watt Light bulb.
