Hello all.I'm trying to build an elctric powered mud runner.I am using the wheely king for this project.I want to build a truck like the ones on tv that fly across a mud drag strip ya know the ones that try and stay on top of the mud and sometimes stall and sink in the mud.What would be a good motor to use?I am now using a hand wound 15t with a 96/15 spur/pinion set up and it does'n get the wheels spinning fast enough quickly.Any sugestions?
