Hi, I stayed 5 weeks for Business in Hiroshima and had enough time to build several cars. I wanted to make a Gimmik machine and started with a MS flex Chassis. After that I made a front bumper based on the guide by Roscoe (). I hadd to change the attachment points but it is working good. Rear bumper is also made according to Roscoes guide (). I added a small plate on top of the two long center screws because I noticed slight bending of the screws after severals test runs. In addition I added a common car cather piece as Mass damper holder for the rear. Also I use a very simple body damper system. The tyres are maroon slick tyre in the rear and grip tyres on the front with alu wheels. When I am back at home I will reduce the tyre thickness. I tested the car on a long track with many curves in a shopping center in Hiroshima. I used Hyper Dash Motor and 3.5:1 gear ratio without any issue. But I think the car is too heavy to be really fast.
