Joysway Dragonfly
The plane is in stock form here with the only mod being to beef up the elevator push rod a little. I found I had to remove the ESC from the battery tray to let bigger packs sit in the right place for COG. This flight was flown with a 3S 1800mah pack. I have flown it on 3S 2200's and though it handles it fine you can start to feel the difference in wingloading. I fly it on 3S 1600's too which are fine and the makers state it can be flown with 3S 1300's, I don't have any to try but I'm sure it would. I'd bet even a decent 3S 1000mah would do the trick for the lightest set up. More info here on RCGroups http://www.rcgroups.com/forums/showth...
