Info, How To Wire One Speed Control for Two Motors.

There are a few different ways to do this. This is a basic explanation of 2 of them. 

Remember that a MOA based crawler requires that the rear motor turn opposite of the front.  i.e. reverse winding.


Option 1. One Speed Control NO Dig.

First make sure you are running a speed control that can handle two motors. Our Current recommendation is the castle sidewinder or mamba max.

A. Start by mounting your speed control in the chassis.

B. install your capacitors to your motors and install them in the car.

C. Next run the motor wires from the speed control to the REAR motor. Solder them on. 

 D. Next you will be running wires from the rear motor to the front motor. We recommend using a low quality wire such as automotive wire in 16ga. Motor end bells are labeled positive + and negative - on each end. Solder the 16ga wire to the motor leads on the opposite side of the motor as you installed the esc wires or on the same tab as pictured.


E. Run the new wires thru the chassis to the front motor allowing enough length in the wires to allow for flexing. Remember to wire them the opposite of the rear. So from the negative in the rear wire it to the positive on the front and so on.

F. Thats it. you may find when you get everything assembled the front or rear motor may go the wrong direction. simply play with the throttle reversing in your radio and or verify you have done this step correctly.




Option 2. One speed control WITH dig.

This method is very straight forward and great if you have a punk dig unit and 3-channel radio to control it with.

Why would you want a Mechanical Dig Control?

The PunkRC Dig Switch is the easiest way to add Dig to your MOA (Motors on Axles) truck.

The Dig Switch adds Dig Steering to Any Dual Motor Truck. When the Dig is turned on, it will cut power to the appropriate motor. When power is cut to a motor, the motor is SHORTED. This helps the motor lock into place. If a OPEN motor is preferred, it may be wired that way.

The Punk RC Dig Switch also features Surge Absorbers to protect burning of switch terminals. This problem leads to shortened life in many Servo Actuated "Dig-a-ma-jig" Dig Switches.

TX Position | LED | Function
Left | Red | Motor #1 Off
Center | Green | Both Motors On
Right | Blue | Motor #2 Off



1 - Plug the Dig Switch Servo Wire into Receiver's Spare Channel (Usually #3)
2 - Solder both Wires from the ESC into the Center Pair of Contacts labeled ESC
3 - Solder both Wires going to Motor #1 to the Outside Contacts labeled Motor #1
4 - Solder both Wires going to Motor #2 to the Outside Contacts labeled Motor #2
5 - Trim TX Channel to Center with normal Endpoints
