Did a little searching, and apparently Feigao makes these motors. They are sensored and rebuildable, very high quality for Feigao. The esc is a HobbyWing speedo, standard stuff. Possibly the same as the Losi esc's presuming Losi buys it's speedos from HobbyWing and puts their own stickers on.

Could be either of the two, they're the same motor. One just has bigger cutouts.
