I think the electronics can handle 8 cells/2300 mah, since it can handle 3-cell lipo, which is higher voltage. The capacity (2300) is probably too much because of weight, but it may fly. The motors may get quite hot due to the long run time combined with the added weight, which in turn reduces efficiency, and increases draw so it's possible you could burn out the escs but IMO unlikely.

I think AA batteries are too heavy.

The AA cells sold by duracell are also, in my experience, inferior chinese cells which do not handle high currents well. I would suggest using them for your TX. The AA cells sold as energizers, on the other hand are made in Japan by Sanyo and are excellent. They are available in 2500's

If you are in a bind and $$ is really tight, send me a pm and maybe I'll give you my stock pack if you pay the shipping....I haven't used it since I picked up lipos.

good luck!!
