Hi,

I fly the Dualsky LiPo 5s 3700mAh batteries http://www.rcaccessory.com/index.asp...ROD&ProdID=286

Charger is an e-station BC-6 http://www.rcaccessory.com/index.asp...ROD&ProdID=241

I strongly recomend this vendor, very service oriented and both my orders have been shipped the same day I ordered.

Flight time on the LiPo is right at 10 minutes doing light aerobatics (loops, rolls, inverted flight). Staying at 75% throttle or lower, your flight time is 15 min or more. Charge time with said charger is 60-70 minutes.
