the truck is alive.
had to remove the original gear box and fit a geared motor to give me more room in the cab.
sound card is now fitted and really happy with the polou motor.
can drive all day long with 5 plus kgs in the tipper.
I think the pump is straining a little ,but it still lifts at the same speed if its full or empty. don't know that that is normal?
just a quick test video
