I used to run crawlers, and I know what you mean about the control and torque. However, the secret with crawlers lies in the esc as much as the motors, as it is the esc that provides the low speed control and micro throttle. It depends what you intend doing. If you hook up crawler motors to an RX18 then the board will probably fry, you are pretty much limited to 400, or 400 sized 480 motors as nothing else will fit onto the gearboxes without some engineering, on top of which the shaft diameter for the pinion is larger on bigger motors.
As has been mentioned, 3:1 gearboxes are the way to go, they slot straight in, and the standard HL motors are more than adequate once you have them.
My Tiger weighs in at almost 14 pounds and is running on standard HL metal gearboxes and standard motors. The only time it struggles is on steep inclines and high obstacles (though it is running Elmod electronics which are tuned to scale speed). I have a pair of 3:1 boxes to go in which will solve all of the problems.
Have fun
