Was getting annoyed by the stupidly heavy frame of the Scorpion Y650 which is made of thick fibreglass sheets (available from Hobbyking). With the GoPro sitting on the camera gimbal and a 4S 3000mAh battery I was only getting 6-7 min flying time.
Had a look at the price of CF sheets and CF 450 size heli tail booms and it looked like an affordable project to design and build a hexacopter from scratch. Above is the basic design and below is the frame plates assembled with the CF booms and aluminium boom holders.
www.multiwiicopter.comin Queensland sell a clear dome with a 100mm diameter which will fit nicely over the electronics.
Just this portion of the frame is incredibly light. I'm quite hopeful that I will get much longer flight times than the Y6 with this design. Sheered one of the bolts in the process so will need to pull it all apart and try to get the remaining bolt out.
