Thanks for the vote of confidence because this is going to happen. I sat and stewed about it last night (planing out what I need) and I want "something" like this. I would even entertain putting tracks on a truck instead of a driven straight axle and put a massive flak gun in the open bed.
So, to pick your brain ... would it be simpler to go with a standard straight axle gearbox (single motor) and weigh down the front end for the steering to be more effective? This would eliminate the need for a dual gearbox set-up and keep it from neutral steering from the rear. I have some Academy motorized set-ups and really don't want to spend money on a 1/18 RC PIV.
Whatcha think?
