Also, the 28 pole Hackers do not play nicely with any ESC except Jeti. I like those ESC's and it's mostly what you'll see in AJ's stuff but those guys also have their own line of motors now that seem to be working out really well. Maybe you might want to check out that option? Sorry, I don't know anything more about them but you could call AJ Aircraft or maybe PM Andrew?

Myself and a friend both have the 2M Acuity running the Himax motor with a 10S configuration and it's a great combination.
