Thanks!


Now, the suspension system:

The m548 uses torsion bars as suspension system with additional shocks on the first and last wheel




Not a m548 but you get the idea


On a m113


the traction bars rely on long rods that are fixed in one end and can twist to provide suspension. Many small cars still use that as rear axle.

After some research and failed attempts, decided to replicate the 1:1 as good as I could

Prototype:




These pieces are where the axles and springs are mounted







The photos are a bit confusing but the 8x 4mm rods are the pivots for each wheel and the wires are spring steel, later switched to a kind of spring blade

The advantages of this system are that can be easily adjusted in stiffness and ride height

Unfortunately, the first wheel on each side cannot be included on this system because the motors were in the way. The solution was putting a shock on the outside. Don't look out of place as the 1:1 has one too

An funny feature it's that, by the design of system,with torsion bars next to each other, wheels are slightly offset from one side to another. Hard to notice but the 1:1 it's also like this
