If the dupont cable is too much rigid you can use 2.54mm male shocket to insert in the gide and solder the cables to these connectors. Anyway, a 3D printable guide is included to be used with 'Dupont' F-M cables and commercial copper braid. The size of hole for the guide in the chassis is 4.2mm, which should allow to insert commercial guides. Ideally, you will have 3mm piano wire and will be able to cut portions of 46-50mm length for the axles.

You will find them also for 3mm and 2.3mm axles. This way you can control quite better the position of the wheels and the contact with floor in the front axle. 10-11mm wide tires will be fine for the rear while 9-10mm wide ones for the front.ĭifferent bushings will allow you to mount the front and rear axles in a lower or higher position, without having to re-print a whole chassis. Try to find 20-21mm outer diameter tires for rear wheels and 19-20mm for the front ones. You can find these rims in versions for 3mm axles or for 2.3mm commercial axles. You can print simple rims in various sizes to adapt to the tires you have or can find. There is not enough space for the actual version of MDS 'chip' in these versions of the chassis, but maybe an smaller one will fit in the future. If you don't mind about using the car in digital mode, you can also mount a 'Long Can' or an 'Old F1' Motor. There is also a version of the chassis for 'Short Can' style motors, which are similar to E200 but have cable connectors in the opposite side than the motor shaft.

We must plug the wires in the right direction so the car goes forward. Between the motors of this kind, you will find some has the shaft in one side or the other, some of them in both! The geometry of the chassis is symetric, allowing to mount the crown on both sides of the chassis. The ideal motors for this chassis would be the E200 style ones, specific for Slot cars, so they work well between 12V and 15V. You can see this body in the MDS Race System Video CHOOSE A MOTOR This 1/32 Slot car can be used in analog mode in any 1/32 car track or in digital mode with MDS System, which is compatible with old commercial and MDS 3D printed track parts.
