There First Prototype

The chassis was then more difficult. A strong, torsion-resistant structure and lightweight construction were required. This proved to be extremely difficult due to the tolerances in the terminal blocks. With a ready-to-drive weight of 1200g (without bodywork), I could say that I had found a good compromise.

Other criteria were durability. A little research on the internet led me to the ceramic lubricant from DryLube. There were several variants, of which the GearLube variant convinced me the most. Not wanting to rely solely on lubricants, I went one step further. I added three Technic Beams with ball bearings to the drive train from DarkIceDesigns. With a few aluminum axles, these also brought the necessary calm to the drive train. But there shouldn't be more than three, as each ball bearing creates resistance in the drive and comes at the expense of the longevity of other components and performance.

The wheel hub itself: The basic idea was clear. A ball bearing suspension with integrated axle adjustments and Ackermann steering. Test drive after test drive brought new insights. The car performed better and better, and therefore put more power on the wheel hubs. So they had to be reinforced. In the next step I discovered that the ball heads made of ABS plastic limited the wheel stroke so much that something better was needed. After a long search I had the solution: titanium ball heads. These brought enormous advantages. Better grip in the wishbones and the fact that they are very durable and therefore reusable.

The body: Lightweight construction was the motto here and of course design was required. Nobody likes to watch an ugly car drive. The idea was to build a mixture of Le Mans racing car and a design study. The result was more than impressive. At this point it should be said that I hope to see some great designs from you too. I was able to unintentionally test an essential criterion of the body during a crash with the camera. Protection of the chassis and running gear. The car drove into the camera at about 35 km/h. A few wishbones later I was able to continue having fun with the car.

The car is still under constant development. But the vehicle is technically so powerful that there will soon be building instructions in the shop.
