The bottom hull plate is .093 inch thick aluminum. The ends need to be bent up. A buddy of mine is loaning a sheet metal brake tomorrow. The motors are 450 watt, geared. 550 RPM. The white drive sprockets will run on fixed axle shafts.
So far I have: motors & motor controler Radio Track drive and Idler sprockets Motor sprockets and chain Suspension system with road wheels. Tracks (but not spliced into a loop) Aluminum hull bottom .093 thick (needs to be bent) Aluminum plate for the hull sides - .125 thick (but not cut yet) Aluminum plate for the hull top - .093 thick (but not cut and bent) I still gotta buy batteries,- waiting to see how uch room I have in the hull. Four 9AH batteries will fit 2 wide and 2 deep. Looks like two 18AH batteries will not fit 2 wide, so they will take up too much space. I WILL make battles this summer!
