Ah, the 2WD caster system (without the casters). A word of advice--while it works fine, you want the traction wheels under the CG as much as possible. (Or rather, the CG over the traction wheels.) Not too much, but if you have the traction wheels in the rear, you want your CG aft of center. This allows for better control.

Bear in mind that 2WD can be pretty squirrely. You might want a 6WD with a dropped center--it turns kind of like a 2WD, but has extra wheels that will assist in traction.
