The chassis is built from so far unknown principles ;-) with a mid-mounted hinge and a flexible and movable weight pan:
Here is is alongside my old Lotus 49
The first test of the new chassis was promising, but it was a bit unstable and could suddenly leave the track in fast turns.
I have since mounted a small piano wire spring to put more weight on the front whees, which I hope will solve the problems.
