Twig Mutant 4 Air Unit
Wanted to have dji onboard recording on a relatively small build. Adding an additional camera always changes flight characteristics and that i didn´t want. So i made a vacuum formed canopy out of 1.5mm acrylic sheet to fit the air unit. It´s thin and light weight but very durable and stiff. The process of making that you can see in the video below.

Motor Choice was a bit bigger than 1404 because of the slightliy heavier air unit. 1506 3000kv work very well on 4s for both 3.5 inch and 4 inch props. What really annoyed me were the short cables they came with. You see that i had to extend every one of the 12 motor wires.

A video with parts of the build and flight footage (thats not the original quality of course) on youtube:
