Have you really been on NiMH/NiCD this whole time?
Get with the program!
Just get a couple of those Turnigy 2S, like you said, and you're set.
Make sure you get a decent charger, and baby them for a little bit, before tossing them around.
That's what I'd do.
As far as the 10,000mAh, I'm not sure why you would do that...
I don't have an attention span of more than... maybe...30 minutes?
Anyways, did you ever get my PM on the Evader?
