Tips for setting up a Mardave V12

There is a myriad of web sites and forums with various tips for improving the handling of your Mardave, and to be honest picking the best tips from each site takes ages. Below are the best bits from these web sites that will hopefully improve the speed and handling of your car.

The following hints are on pretty much every web site and are considered to be “standard” upgrades:

-Flip the A-arms over so they are upside down, and fit 2-3mm of washers to the front mounting position of each arm to give caster to the front wheels which improves stability and less likely to make the car spin out on corner exits.

-Change the kit servo saver for a more reliable one. There are many on the market, but make sure you get one that suits your servo as different makes of servos have different spline fittings. The major name that is banded around for this upgrade is a “Kimborough” type servo saver.

-Upgrade the track rods & ball cups to either the heavy-duty type sold by Mardave or any threaded turnbuckles from manufacturers like HPI or Schumacher, but make sure they are the correct length to give neutral toe-in. (Neutral toe-in to 1 degree toe-out will give the car an aggressive steering response, giving a little toe-in will stabilise the car more which is better for beginners)

-Ballrace the rear axle. This is a must for ultimate speed. But don’t fit them and forget about them they will need looking after if you want to keep your top end speed. Every few weeks strip down the rear end and give it a clean with a soft cloth, and oil them with thin bearing oil or sewing machine oil, also check they turn smoothly, i.e. no lumps & bumps within the bearing. If they do feel notchy remove the shields and clean. The only problem will be is the bearing race will get dirtier a lot quicker as the shields protect the inner race.
