Jim, Klx, Chris,
Thanks guys. I use XPS on some of my stuff and they indicate a need for 350-500 mAh for each servo (with 5 digis thats a min of 1750 mAh!).The P-7 will be Fut FASST 2.4. I think the the 3152s and the 821s are similar in current drain, I need to order something asap. Keep it coming, all ideas are useful. I considered LiPo but I think I'll stick to NiMh for now.

Hooks P-7 Specs:
ACE MP8K with Fut TM-8, 617 Rx
Servos- 3152s (analog on retracts)
Rhom Air retracts (arghh) could still go fixed gear
NIB Kraft .61, have header an pipe, might use Kraft muffler
Battery, hmmmmm, thinking 4 cell 1650 mAh, maybe 5 cell (but more internal resistance right?)
I could always bust out the Kaos (it flew nicely the other day)!

Hey Chris, a first and second place eh! You're doing nicely thus far this season!
