This Gearbox are fantastic, I use since 2011 and after 3 competitions still perfect. I lost one wheel an the axis survive intact. Very solid, good for exposed wheels robots!

Great and Strong Gearbox!
That's the best, strong and practical gearbox that you could find to use with a DeWalt.
It has 8 screw holes to easily mount on your robot. The output shaft is mount directly on the gearbox, internally supported by 2 large ball bearings, so there is no need for extra pillow blocks and it can easily support and handle a lot of weight and abuse.
It also has 2 extra custom clamps to help hold the DeWalt motor (since the top of the DeWalt New Style motor could be riped of if mounted only with the screws)
This gearbox was used in the Caolho (Combots 2010 Featherweight Champion). Here you can see Caolho pushing robots that are 4 times his weight: http://www.robocore.net/modules.php?name=RC_Midia&id=356&tab= (Caolho is the little dark one with the trident mount on the front)
