After talking to the folks at Hacker here in Phoenix and the folks at Castle Creations today it is apparent that I need to move on to a different brand ESC.
At the moment, I am using a Castle 80HV Edge ESC with a Hacker A60-7S motor. The motor just doesn't have the power that it did using a 80HV Ice2 ESC.

Both companies confirmed that there is a problem with the Edge products when used with any 28 pole motor. Castle seems to have no idea of when the
problem will be corrected. I was advised not to use any of the Edge products with any 28 pole motor.I am now waiting for my 3rd replacement ESC but I
am pretty much afraid to fly the new unit until the issue is resolved.

I have looked into other controllers but I thought that it might be best to see what others are using. From what I have seen and heard, the Jeti products
might be the best option.

Thanks in advance for your input..
