Hi Crius,
I'm happy with these boards. I have 3 of the 3ton Elmod boards. 1 in an Opel blitz and 2 more in a 1/12 King Kong Rc Zis 150 and Zil 157.
They seem to work pretty good, I am still learning the different ways to configure them. You can change a lot of the control, sounds and light functions.
You can tweak the functions like headlights, convoy lights, brake/tailights and horns.
With the exception of the issue I had here which wasn't bad I have been using them for about a year with no problems.

A not too good video here:
