Very nice! I'd like to see those gearboxes once theyre up and running, they seem very good on paper and the price is right, I just have not had the chance to talk to anyone who's had them running yet.

Which tracks did you get specifically? I know there are a few metal options for the Abrams; solid metal ones that are apparently pretty heavy, and the rubber padded ones from HobbyRaw (as far as I know, probably elsewhere) that have had good reviews & are much lighter.

*edit*

Whoops, I now see that you used Leopard tracks. How are they fitting on the Abrams gear?
