It was a hard and long way to go... I had to customize many parts to get it together and it still needs some tuning.
It flies stable now in up and down position. I still need to do some PID tuning on the Pixhack/APM and the Gimbal.
But I am very impressed of the performance over all. I get about 20mins of flight time.
Here some of the hardware I used:
Motors: Emax MT4008 380kv
Props: 14" 14x55
LiPo: Turnigy Graphene 6S 8000mah (the normal ones were out of stock)
ESCs: DYS XS30A
FC: Pixhack with M8N GPS
Wormdrive: 8mm (from 3D Printer), 360degree Servo with Arduino Controller
Weight with battery: 3.3Kg
Frame was printed in PETG, Canopy in PLA and the Lift Linkage Sweep in Carbon PETG
