This is my second multirotor build. After building and flying David Windestål's tricopter v2.5 design I decided to build a quadcopter. I wanted it to look a lot less industrial and a lot more organic, homo sapiens even. I took my design inspiration from the great Leonardo Da Vinci who was the leading artist and intellectual of the Italian Renaissance.
I adjusted his arms and legs a little to come up with my instance. I also determined to make it a folding frame. In the end, the arms fold down only.
Here is the main body, with arm and leg pivot points marked, and a custom chest (electronics) protector made from a 7UP bottle heat shrunk over a plaster of paris model.
The top of the second layer contains the ESCs, actually a 4 in 1.
The bottom of the second layer contains the Ultra Bright LEDs and their requisite resistors to use 12V.
The bottom layer supports the battery and low voltage alarm.
The main electronics attach to the top layer under the chest protector.
All propped up and ready to go.

Dusk flight with lights. The CC3D board allows a very stable hover and excellent handling. The lights are visible in the daylight too and help me to keep orientation.
I hope you enjoyed this posting. Flitetest is the best.
