At the moment Im hamering motors and spedos in it to see how various combops hold up - I kno0w I can read it all on the US forums but nothing like doing it yourself. I have a meeting this weekend at stoke but Il be running my nitro as its been too long since I raced that. Its years since Ive done much 1/10th stuff but it would be cool to get to one and have a play it sound like there are a few of you guys who attend nationals with them now. No chance of heat on the side I take it !
Cool - yep the Kyosho spur fits right on the K car
The diff does also drop in other cars but never tried it on either of your two but prob worth a try.
