OK,
So I placed an order at Hobbyking..
I bought this gear head motor..

Some of these nice little steel universals..

Plus a couple of LiPo LV alarms, and some Deans connectors.. Its time to replace the Tamiya plugs in the trucks, and put some of my older LiPo's back into use..
I'll just have to wait til it all arrives and see if the gear head motor has enough torque to lift the tipper.. If that fails, I found a gear motor on eBay that has 4.5KG/cm of torque..
