A rc-tractor scaled 1/87 is a challenge. But if it have a trailer to hide the electric, it is possible. So the tractor looks fine and the motors and battery are invisible.

technic
In the front of the trailer you see the motor. By a cardan shaft he powered the rear axle of the tractor. At the bottom of the trailer you see the servo. It moves by a cable the frontaxle. So the reciver, servo and the speedcontroler has enough space above the servo. The battery is under the roof of the trailor. Normaly this battery powerde a cellphon. It is a "Lithium Polymer cell" 3.6V 135 mA.
