    I've been working on some of my RC cars for a change of pace. That doesn't mean I've forgotten about M4WD.
    Here's a sneak peek of one of the side projects I've been working on for a little while.

    I got the new wheels today, then decided not to use them [​IMG]
    After thinking about it, although using a full set of one way wheels would be nice and reversing wouldn't be a big issue, after careful consideration I realised......there wouldn't be a brake!

    So I used the spare wide one way wheels I had left rather than open a new pack and used those on the front to aid with steering and to remove unnecessary resistance from the plastic joints.
    The rear I just threw on a regular set of wide wheels so the rear axle is full solid, this will allow me to brake and reverse.

    I haven't properly tested it yet though, I have to wait on Monday or Tuesday for the new batteries to arrive so that I can modify the connectors (don't want to on other batts because they're all ready for the other cars).

    I tried to create a steering crank system and used the tamiya steering kit wheel hub to make the steering system. I also used the plastic universal cardan joint that came with the micro jeep crawler I made recently as I upgraded the shafts on that to metal. I think I have about the same amount of steering throw as a Kyosho Mini-Z.

    I decided to put the unused Plasma Dash motor in, as I figured it would be able to take the power best of all the motors and should be easy to change brushes if needed. It's far too strong but I can always tune down the throttle speed on the Tx to something more comfortable anyway.

    Changed the tyres to some hand made foam tyres. Runs much smoother, quieter and better handling now I can slide the rear end around to compensate for lack of steering angle.
