I built a 3d printed micro octocopter more than 2 years back, when there isn’t really any brushed FC for more than a quad configuration. These days toy grade, quality multicopters came readily available, I decided to build one with more than 4 props.
Recently bought a FC for Eachine X6, from banggood.com, with 3d printed polyamide frame(Taulman bridge) on my heavily modified Ultimaker(200W aluminum heated bed-capable of heating hotter than 150’C, fully enclosed passively heated chamber., dual fan, dual extruder, actively cooled stepper motors, larger power supply and etc). Polyamide is rather flexible thus it is unbreakable and will survive in numerous crashes.
I mixed using used and new motors and since they are brushed micro, used motors provide less power than the new ones causing drifting and yaw. New 7×20 motors and hubsan x4 props(proved most efficient) from banggood is on the way and I am hoping to get better lift and battery life.
Total weight with FPV gears but the battery weighs 53.9g.
Recently bought a small RC car from Banggood.com, and just added FPV gears then drove with my ground station.
Over the winter I got married and took a break for a couple of months, I got into FPV (First Person View) and toy grade RC stuffs. I also built a quadcopter with 3d printed nylon parts-nylon is such an awesome material to work with, it is almost impossible to break, thus perfect for impact resistant applications. Maybe I post it later.
Anyway, equipment on the video as follows;

That “infill not touching perimeter” print, which it works fine now, in 120mm/s speed with 8000mm/s^ acceleration.
Over the week I have been perfecting the super tight bumper for my iphone. After more than 40 fails I finally found the right formula. It’s so tight you have to (sorta) pound the iphone to fit in.
투톤 아이폰 범퍼. 일주일간 40번 이상의 수정을 거쳐 드디어 완성작이 탄생했다. 초 타이트 하므로 플라스틱 특유의 뻐벅댐이나 와글거림이 없음. 그래서 끼우기도 힘듦;
