I worked with Lucien miller, innov8tive designs, and Randy moody, RC dude hobbies, with the creation of my DARPA bird. Been talking with them and their design of a GoPro and a DSLR gimbal that will just bolt onto their frames and was asked if I would help them test it out. I said sure and got a custom 800mm hex made up and sent out. Finally got it completed and flying and it's awesome, Very rigid and lightweight. Here's are the current specs.
Cobra 2820/14 motors (same ones I used on my DARPA bird)
NL 40amp speed controllers with Simon K firmware
Gem fan wood 12x4 props
DJI naza with GPS
Gaui crane 2 gimbal (will soon be replacing the stock servos with savox ones)
Gopro 3 black
1 watt 1.3ghz video transmitter
Batteries I'm still playing around with 3S and 4S
At full throttle on 4S this bird will produce 30lbs of thrust. More then enough for the amount of batteries and the canon rebel ill be flying once they send me the bigger gimbal.
My canon rebel
Temporary arm attachment, taller then my 2 year old
