50+ km/h Hybrid LEGO RC Car 2.4GHz

[janssnet]

For some time I'm working on a 2.4GHz RC controlled LEGO car. Trying to create maximum speed with a LEGO-based car using standard RC-components (sorry, not for purists).

To make this work, I introduced some rules. The car must be build using LEGO parts, except for the battery, motor, speed control, steering-servo, remote-control and receiver (and optionally a car-body). 

Fully agree with comments regarding LEGO not being able to match RC-performance. But, nevertheless, I enjoy pushing the limits to see what speed can be achieved using (mainly) LEGO. It has been a great journey. Lots interesting problems to solve: reducing wear-out, maximizing traction, optimize direct steering, increasing control with suspension, etc.

Happy to share the results so far. Haven't done a proper speed check, but some rough calculations show a speed above 50+ km/h.

Open for comments, suggestions, improvements.

Hello @janssnet

This car does not belong in Scale Modelling Forum.

I will move to the main Technic forum, there are few guys there making their own Lego-top-speed cars, but they use normal motors.
