I have the 3dr quad kit and had a bad ESC, (still waiting on a RMA for two days).
The other 3 work fine with my 2200mAh 3cell lipo's. But would like to use a 4cell A123 2300mAh packs instead. I know they are heavier but they have always been my choice for durability, handle the cold weather better, and fast charge @ 10A+.
The problem I see is the stock ESC's (20A, yellow heat shrink)auto sense for lipo only.
Are there any other choices for ESC's that would work?
I've always used the Castle Creations Phoenix series before for their programability http://www.castlecreations.com/products/phoenix-25.html
