I see what you mean, if the setup is sucking 62A , with a 3400 battery, it works out to about a 3 minute flight time, 5000 are a bit better at five minutes, I suppose that is full power all the time.

I have been eyeing up the Hextronik Lipos on the United hobbies websites, 5s 4100mah , max discharge of 15-25 C , this would give me a 4 minute max power run.

Where can I get 5000 lipos ?, but at those nice cheap prices of United Hobbies ??
somehow I think its going to be those 4100's
