For you first tank I'd recommend sticking with what has been proven in combat. The M1 motors are your best bet for propulsion.
http://www.tncscooters.com/product.php?sku=106115 These can run at 12V just fine and at that voltage will provide a 3 to 4mph speed. Frank Pittelli can provide you with custom drive sprockets that will adapt the M1's to standard ansi chain. For a cheap controller you can build the on/off Tri-Pact controller: http://rctankcombat.com/articles/speed-control/07TriPactSpeedControl-large.jpg If you want proportional control I'd recommend bitting the bullet and get a decent dual channel mixing controller: http://www.robotmarketplace.com/products/RP-SWDR.html http://www.robotmarketplace.com/products/VT-RDFR33.html If those controllers are to much for your budget someday Cheap Control Systems is supposed to introduce a controller based on generic scooter controllers but you may have to hold your breath a while for that.
