Ive thought about using a ''tractor'' as well. There's been a few german halftracks that have been sold on ebay the last couple years that are remote control. One went for $600. But they are 1/6th size scale. great for most of mine I suppose, but buying a brand new one of those half tracks is well over a couple 1000 dollars.
Another option Id thought of was using an old Willys pickup body on an r/c monster truck and painting it military colors.
Randall, I have a 1/6 german half track - the problem is the weight. The Stuart weights about 25-30 pounds and needs more weight when I try to climb on concrete or in rough terrain with the airplane in tow.
The half track is a trail and error thing - I have the old speed controllers and motors from the Stuart left over may this fall I go on it. But before that I like to built something like that in full metal...
