I just meant that it would really not be to any accuracy of scale. IMO the gear boxes and ESC would be a little week especially at 7.2 volts. You really would want something up in the 12 volt range to runt his tank .Now you can get big motore like 540's that can handle up to 12 volts but I'm not sure the gear boxes would hold up to the stress that would put on them. Maybe a set of steel 3:1 gearboxes from Bill at RCCommand should be strong enough. It would be a good idea to replace all the bushings for bearings. This will help add durability to the box.  El- mod may just be the electronics package you should go with, they even have a correct Abrams sound card. Would like to go this route with my HobbyEngine 1:16 scale Abrams. As usuall Dan has some pretty good experience with this tank I believe. Thanks Dan.
