I have a T34 that is now converted to use Pershing Gearboxes BUT before that I used the 280 with standard gearboxes... the problem was striping the final drive gears... they did not last long at all (less then 5 min in one case) . ... I would not mind trying those metal gears in one to see how they hold up. could make converting the T34 to Full Option MUCH MUCH less expensive and less time consuming. Those tracks look awesome
