Here's a quick look at my recent QQ190 "Tank" build. The flight controller stack went together VERY neatly, and I want to show you how I've wired everything up to get a tight, clean build, without compromising ease of maintenance.
Bonus feature: In my opinion, the BEST way to mount a buzzer to the Xracer F303 v3.0.
