Both bots use castle creations neu 1515-2200kv motors... but there both customised with the front face plates removed, 10mm alumec fronts that key into the motor can with twice the amount of mounting bolts in the can than standard, with helicoiled threads, larger 10mm high speed bearings (up from the standard 5mm), custom shafts and a support bearing for the other end of the shaft thats pressed into the bulkhead... basically took them of the shelf and "combat hardened" them.

There great motors off the shelf... NST bent the shaft on mine slightly in 2013 so i went all out for 2014 and it worked great.
