Dig and xr10 cutting break with a DX3R 3ch
 

Correct me if I'm wrong, but I should be able to use a Punk dig 2ch switch for standard dig on the Axial XR10 and use the three position 3rd ch on the DX3R for the cut break.

Dig Switch 2+ (2 Channel Only)
Dig Switch 2+ for 2 Channel Systems

This Unit Requires NO spare channel For 3Ch systems, see the Dig Switch 2+ for 3 Channel Systems. WE RECOMMEND: Use 3CH Dig Switch if your system allows (faster operation)

The Punk RC's Patent Pending Dig Switch is now shipping, at least weekly, within 2-5 business days.
The PunkRC Dig Switch is the easiest and more reliable way to add Dig to your MOA (Motors on Axles) truck.

The NEW Dig Switch 2+.
The new 2+ version is much like the original, but more reliable and powerful.
Higher current connectors to prevent burning out the circuit board if you arc a motor.
Run one motor shorting and the other freewheeling.
More Robust circuit design prevents higher receiver signals from burning out the unit.

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 you want a motor to freewheel instead of lock, desolder either bead of solder, marked with a "^" above the work "Dig" or "Switch" for Motor1 or Motor2 respectively
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.

You could but i don't suggest it, you have to do weird procedures with the steering to get the dig engaged which could hurt you worst than the dig would better you in some cases. A 4pk or another 4+ channel is needed, you could always do a build like i did and do a 6 ch http://www.rccrawler.com/forum/showthread.php?t=267832

Well ya could. :roll: I'd sure use it on the cutting brake and instead of the dig but really ya could almost sell the 3r and not buy the punk switch for the money of a 4pk (at least a used one)."thumbsup"

Thanks for the input guys.
I could look into selling the punk and the dx3r I guess.

I don't think the 2ch dig would work for the cut brake. Its not 3 position.
