We just completed the maiden flight of our 3DR hex. We're trying to optimize flight time, hence the large quantity of batteries. Here are our basic specs:
880kV Motors
12x3.8 SlowFly Props
APM 2.5 w/uBlox GPS
AttoPilot 180A voltage/current sensor
FTS system (using 2 DIYDrones Mux boards to disconnect APM and kill motors)
3DR 900MHz Radio
Spektrum 6 Channel Receiver
6 6000mAh LiPos (36Ah!)
At hover we're consuming 47A, which means we could hover for around 37 minutes (landing with 20% battery life left).

what brand of batteries are you using ?
Is this theoretical values or tested? I find it really heavy and pretty sure you cannot get 37 minutes...
