Re: Motors to replace the EV Warriors [TANKS]

[himself-at-adamwells.net]

I'd just like to correct my previous statement. The "new" DeWalt 12 volt motors 
(Part number 396505-20) are able to put out 33 ft lbs, not 29. So, they spin 
about 84% faster in low gear than the 12 volt EV Warrior with 1:9 reduction and 
put out identical torque.
