This is my latest multirotor, it was made entirely on a Laser cutter every single part (but the electronics)
The camera Gimbel is also laser cut and the entire thing is my design.
Just thought i would like to get your guys thoughts on it.
~A few notes on the design
The arms are raised above the CG to give stability in stable hover and decent.
The motors have a 10% outwards tilt this gives a higher flight speed by allowing a larger tilt in flight, it also gives stability when descending or ascending as the motors give a minute amount of horizontal control.
the under mounting of the motors give a around a 9%efficiency increase as the air is not thrusted onto the arms.
the overall result is a inherently stable design, in one of my recorded flights the motors are completely cut for a few seconds and the copter glides down as the motors auto rotate, it didn't flip or roll or oscillate, it simple glided down.
here is move video footage

Amazing, you built it upsidedown by mistake and the APM is so good it still works. ;-)
weighed in at a bit over 4kg with gimble and batteries
use 8 kinda crap motors
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=...
Donkey st4010-820KV 194grams
4 x 300mah Turnigy batteries 239grams
40amps ESC's 40grams
so 1.554 KG on the motors + 320 gram esc's + 956 grams on batteries + 500grams all in for wires, apm telemetry gps props gimble
Apm 2.5
so 3.3KG just from the electronics
this plus the 900gram frame gives 4.2KG
but it has a huge amount of power, it rockets if i want it to.
Nice aerodynamic catches,, I was figuring some octopyssy style 3d printed frame like this.
Cleaner to push air, and tilt is good idea.
