    Rough estimation of Kv for stock motor?

    Do you know what the Kv of the stock motor is? (roughly)
    And what pinion does it come installed with?

    Thanks!

    Pinion 14t and if it's something like the Mabuchi 775:

    Thank you for the reply.

    Perhaps a better question would be:
    What kv would be recommended for 6S?
    My goal is not land speed records. Just good, strong, reliable power with great run time.

    Thanks again!

    you could step way down to a 450kv (or around there) some of those take 8s and more...would be for an airplane or heli....ive seen em for way cheap and they look pretty cool too...maybe somebody could chime in with a link

    For RC, I primarily fly helis. I have quite a number of lipo cells lying about. From 1S 110mah to 8S 4200 mah. I think a great pack for this truck would be 2x 3S 2500 packs in series, which I have a few of They would fit perfectly as well.
    I have great access to brushless motors of all sizes and kV ratings. I know what ESC I want... I just need to get a feel for what KV to get.

    Thanks again!

    The E-revo (brushless version) comes with a 2200kv motor and w/ stock pinion has a 18.83 gear ratio.
    The Summit has Low: 70.18 and High: 25.34 gear ratios.

    It seems, then, that somewhere under 2200kv would be good. I don't need no "65mph & beyond", haha.
