Its easy to modyfied the servo to make it working like a motor look at the photos of the inside the truck, you can see electronic from the servo outside plus this small wheel on the top of the truck im using to trim [set up] the servo on zero, other wise it will start turning one direction... well to make this ''motor'' you need to destroy one servo to use some parts in ''motor'' I can upload the ''plans'' how to make this ''motor'' if you want:)
Besides i decide to keep this truck:) I will play now with my buggys:), Make some mods:) etc:)
For the electric motor [normal one]... ill keep the serwo ''motor'' for now:)
