I have this:
Hyperion 4s 3300 35C flighttime 9 min. 2800mah used
Turnigy 4s 3000 flightime 8 min. 2600Mah used
Turnigy nano-tech 4s 5000 not used yet. think/hope 12/13 minutes.
I do not use lipo's in paralel, it's a bid tricky. Since my hexa doesn't glide I take no risk.
I think the flight-time with a 2200Mah will be to short, around 6 minutes.
Usually I am near the landing-spot a minute before.
