From Exotek Racing:
100% cnc machined vented motor plates will keep your motor running cooler and longer for that extra edge. Aggressive cut outs allows the heat that builds up inside the gear cover to vent out thus lowering overall motor temps greatly.
The extra machining reduces the weight (and CG) down to 11.8gr but the critical motor mounting areas are still intact to maintain solid motor mounting and gear mesh. Extra cut out on the bottom side makes sure that debris is ejected for free running gears.
Laser etched, polished and anodized black.
