it depends on what type of crawler you have. MOA (motor on axle) or a shafty (center transmission with driveshafts going to each axle). it also makes a difference in shaftys which brand of crawler you have.

basically in a shafty, you have a "dig" unit that mounts to the back of the transmission. the driveshaft mounts to the "dig" unit. then you have a servo that attaches to the "dig" unit. in normal the dig unit locks the output of the transmission to the driveshaft so the rear axle is powered. when you engage the "dig" the servo moves a collar and disconnects the driveshaft from the dig unit. this allows only the front axle to be powered.

for an MOA rig, there are a couple different types but the dig function is electronic. people use something like the "punk dig" unit where whe you engage dig this unit cuts the power to the rear (or front) motor. a better way is to run dual esc's and dual esc mixing on your transmitter. this will allow for total control of "dig" and porportional control of the front and rear motors for overdrive/underdrive situations.
