90 ton 1/14 metal excavator scratch build w/embedded PC

The smoke generator was the surprise that I promised earlier :-)

It works quite well as you can see on the video above. I mounted it so that the output is at the same location as the exhaust on the original CAT 390 F.

I have the 12V, "standard NON ESC" version with red color. I control the variable output with the first channel on the fourth motor controller.
