Doug,
I'm glad I could be of help. 4 brushless motors ? and 15 amp esc for under $100? Which ones did you get? Wait, did you get a quanity of 4 - 15 amp esc's also?? Ok, that should get your Herc motivated. Actually, I like that motor better than the Motor Max that I have. My MM450 will get hotter than tHe blue Motor from aarchobby turning the same prop with the same battery, and the blue motor is running at 950 Kv higher. I think it's cause of the design of the bell. I'm kind of curious about the li-po battereis he has, what quality they are. Only way to find out will be to get some eventually I guess. The guy that runs that site is pretty good to deal with.
