I have 2 battery packs that I would like some advice on, I have my 220 mah NiMH Maxwell pack, And a FMA Direct 600 AE 1/2 cell pack. The NiMH weighs 2 ounces with 8 cells. And the 600 AE weighs about 5 with 7 cells. What would my flight times/ preformance be with both of theese? WIll the 600 AE be to big? Thanks in advance guys!
