Meet the 4 inch!

I started to think ahout this project after the 7 inch drone became self aware and flew away. I looked through quiet a few 4 inch frames and settled on a slightly redesigned dave_c lr4. After building it up, I decided to take a turn to maximum weight savings and neatness. Therefore all the wiring is black, all the heat shrinks are black, etc. To make the drone even lighter I redisgned a frame into a unibody, made it a bit narower in the front and shorter in the back. And this is the finished product 215g all up weight with an 850 4s battery, longest flight times was 16 minutes, flying very calm. The weight also allows for running a insta 360 SMO and still beeing sub 250g all up.
