Hi tenerifecrimson,
Its certainly an interesting idea.

The R/C should be very interesting using Heng Long electronics.
The problems will be ..
Linking the gearboxes to the smaller metal bars that are probably used as axles....you might be able to 'overdrill' one wheel per side and fit the usual tank gearboxes....BUT...the major problem with that is that it will have only 2 wheel drive, where as the actual vehicle probably has 6 wheel drive.
I also suspect that the actual vehicle can 'Turn' the front wheels to steer...so that would be another problem to overcome.
A happy medium would be the 4 rear wheels driven with the front wheels steering, unfortunately I think that this is going to be a challenge....and you get to sand off the moulded on tools..I HATE that when the manufacturers do it.
