Hi all, Today I could finally try my actual MA Chassis build on my homemade track. The car is equipped with Mach Dash Motor and Carbon plates except for the rear swinging mass damper, which is mounted on FRP plate. The rollers are 6 13 mm ball bearing rollers and 2 13 mm plastic rollers. Under front and back plate there is the red brake sponge installed. Gear is standard 3.5 : 1 with ball bearing at the green wheels and 1 washer at each green and pink gear wheel to reduce axial movement. The shafts are hollow and also equipped with ball bearings. The chassis is not cutted so the car is quite heavy, about 217 gr with batteries. I tried to attach aluminum wheels but it was difficult with the hollow shaft. I ordered a wheel puller and will try it next time. My track is around 33,8 m length and fasted time was 8,9 seconds which is ~ 13,8 km/h. This seems to be quite slow. What is your experience with Mach Dash Motor? Which speed can be achieved? The other cars are equipped with Atomic Tuned Motor and reached between 10,5 and 10,1 s.
