Right, I'm not entirely sure my set-up is perfect but I'm working on it...
I'm flying a H-800 (Hobbyking H-800 Hex frame)
On this I have the following parts....
DYS D4215 - 650kv motors from RCTimer,
RCTimer 45A ESC's,
Tarot Retractable Landing Gear,
Tarot mounting parts to mount the battery plate and Gimbal,
A cheap eBay 2 Axis Gimbal,
Pixhawk FC,
FRSky X8R reciever,
3DR Radio,
MAVLink board and OSD.
And a 4S, 6200mAh Zippy Compact battery....
Now, I'm getting 6-7 minutes comfortable flying time....
I have recently upgraded to Mission Planner 1.3.36 .37 Doesn't work for me?) and loaded Firmware version 3.3.3 so I needed to re-cal' my accels and compasses....
after that I hooked up my amp meter and throttled up to the point it wanted to lift but not quite...
My amps were up at 28ish.... Would that sound about right for a copter with an all-up weight of about 4.3Kg?

Calc shows that you need 36 amps to hover. And your throttle is near 60% at hover.
My 800 quad with 3-axis gimbal needs 20 amps for hover. But it has quite efficient setup.
I would tell that it sounds right for me.
You can connect second 4S 6200mah in parallel. As i see in calculations that you will get 9-10 mins with two batteries.
Thanks for the reply Vital Belikov...
I really must have a look at my telemetry screen to see what Amps I'm taking in the air...
On the stick, it's only just over half way...
I need to find a way to make it more efficient... I am actually building a bigger battery plate so the second pack is going on... :-)
No problem :)
To be more efficient you need to find ballance between low kw motors, big props, light weight and big battery :)
Ha! That simple! Lol... ;-)
Ah... I knew I forgot something...
Prop's are RCTimer 13X5.5 Carbon....
The batteries are very new at about 5 full flights plus using them at set-ups....
