Turning a LEGO boat into a (super fast) RC car

Recommended Posts

Hi folks,

This is not for purists. Contains modified and non-LEGO parts.

My urge to build a super fast LEGO RC Car often stopped at the stage where the body needed to be build. Seeing all the great designs on forums like this, it somewhat discouraged me building my own. Besides the fact that these bodies come with some weight and will not hold a crash a higher speeds, I had to come up with something else.

As a result of an earlier project (building a fast LEGO boat) a had some damaged LEGO Hulls (54779). Since a car body works basically the same as boat hull (but 180 degrees rotated), I thought I'd give it a try.

Have a look at the result in the YT video. It works fine. Gives strength to the car, the aerodynamics work well for good driving stability and it is not that ugly :) Called it The LBOW (Lego Boat On Wheels).

Included standard RC components: ESC, brushless motor, 3s Lipo battery, digital steering servo and .... a Gyro. Resulted in a very fast RC Car. Theoretically this should be able to reach 100 km/h. Speed test will follow (need to find a good track first).

For those trying to do similar things, I'd strongly recommend to add the Gyroscope to your car. It prevents the car from breaking out at higher speeds. Very useful.
