We obtained these as part of a closeout buy. The fans are 6 bladed and plastic as are the housing units. The motor is a 2315KV brushless motor of unknown brand. The ESC is a 15A esc. I do know these were for a 3s 1700-2200 mAh battery setup, so that makes it a 100-150 Watt power setup.

I picked up two at the Toledo show, will not work with 2s, work great with the 3s. (Posted on 4/7/13)
