Izzy, I only use the Servonaut S20 as a speed controller. I don't have the sound or lights modules. The S20 is very quiet, much quieter than say a Tamiya TEU-101BK. Can't say for certain, but it "feels" like there is more resolution to the control. I can make the truck practically inch forward or reverse with just a tiny movement of the throttle stick.

And I like the brake and reverse light feature it can be directly connected (with the appropriate resistors) to the ESC. I would thoroughly recommend a Servonaut S20 ESC.

I also purchased an M20+. This has all the light connections on the ESC itself, but I can's seem to find how it hook it up to use other channels for lighting control. I have not used because the instructions are completely in German am too worried that I would fry the electronics by hooking it up wrong.

Dave, thanks!
