Lego RC Trial Buggy With 2-Speed Transmission

Recommended Posts

If you follow me on my youtube (http://www.youtube.c...ser/1nxtmonster) you might have seen my RC crawler project. It used 2 RC motors and was quite fast and well performing. You might have also seen my RC rally car videos, they were fast and nimble.

However, I want to combine the best of both worlds in one trial buggy package. So after a lot of trial and error, i was able to incorporate a 2-speed transmission into a crawler with RC motors. The ratios are 15:1 (slow crawler) and 3:1 (fast buggy). It is shifted by a mini linear actuator via an m motor. I'll do some more testing, and as usual this most likely isn't the final version.

Amazing! The two speed transmission sounds perfect. Crawler speed and Buggy speed. That is all you really need. Good work!

I too have built a 2 speed transmission in my crawler, it provides for much better driving!
