Few month ago, I decided to build long flight time UAV. After quick google search, I came to http://vimeo.com/84302289 . Result is awesome in my case. I ordered everything for this setup.
Motors: Tiger U8 100KV
Propeller: Tiger 28x9,2
ESC: Hobbywing Platinum 30A
Battery 6S4P GEB8043125
Now, I come up to next problem, which is PID tuning of this large craft. People who made these kind of setups are flying with DJI Naza flight controller. I prefer PixHawk with ArduCopter on board :)) .
Did some one do these setup?
What kind of PID values did you have ? Or is there any way to calculate such values? I need some close values to fly on Stabilize mode to figure out auto tune.
As you know it's dangerous to fly with wrong PIDs on such huge and expensive quadcopter, where each props cost 160$...
