The motor in the Blade 450 is a 6 pole 3800Kv 420 Helicopter brushless motor.
Part number EFLM1350H (46$)
It does the job pretty good and is quite powerful while not getting too hot.
Blade offers an upgrade with the 440H 4200Kv motor (EFLM1360H at 48$).
While these run great and lasts for a fair amount of time, i recommend lubricating the bearings in them every 15-20 flights or so with silicon lubricant. (Thanks to wbefield on helifreak.com).
