been farting around with this for ages , i got some rough wheels cut out and i got the tires on , but these motors, as beefy as they are can barely pull the thing along, a dinky bump in floor will stop it dead, and the whole thing only weighed 40 - 50 KG. As well as this, on one of the motors the gearbox was really on its way out. Ive decided to use the good motor/gearbox as an improved electric lifter on my FW and as for the dead gearbox , ive taken the motor of and im going to use it as a new motor for my diy wind turbine .
