Only minus is that is has only got one out, and not 2 as you’d often whish for a robot.
I really do not know why we could not make that work about a year ago or something - it must have been because we had less clues than today, I do not know… It just works perfect today

Yes I have used it with success too in Robot Hansen. Does yours also make a loud irritating noise when running? (Hmm… actually I don’t know if it’s the motor or the regulator that makes the noise).
I suspect that it is the PWM that is set in the audible frequency range - and I think I read somewhere that it is more efficient to do that than to have it at higher frequencies.
We’ve come a long way since back then! Well… I haven’t really done that many robots, but I do know a lot more about electronics than I did back then 
No noise here!
