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.
