To test the ability of using larger pack for longer flight time, I use 2 packs 3s 2200mAh 20c lipo. It fit into the fuselage with some minor surgery. The fuselage is very spacious and easy to modify.
First flight was abandoned as weird noise originated from one of the ducted fan during full throttle take off. Luckily, this is a twin ducted fan version.
One blade is missing !
Something seems pluge into the foam
A 5mm stone !

The EDF destruction is horrible as a stone is sucked into the duct through the cheater hole at the bottom. I should have sealed all cheater holes underneath !
Otherwise, the EF2000 flies great on 2x 2200 provide longer flighter time ~7mins. The extra flying weight of 180g is significant, thought it is more "stable".
I will try a single 2200mAh 34c lipo next time for better aerobatics..
