Flies as good asF4 or F7

For 8$ this is a perfect FC to stock up on in case fpv is ever banned for some ****** reason.

Great Flight Controller!

Not sure what build I will put this in, but I love all of SP Racing's products and the price was right! It will probably go into a generic build at some time in the future.

Old School Tech

Thought it might be fun to build a 3D printed drone and use this flight controller for it's old-school flair and low, low price. After being spoiled with more modern tech, the project was kind of a non-starter from the get-go. (The latest version of Betaflight I was able to get to successfully flash is 3.5.1) This FC requires a separate 5V supply, has no OSD nor oversize holes for mounting isolation (gummies), and it's low gyro / PID update frequency along with the F3 processor makes it so sub-par to modern flight controllers that I couldn't bring myself to use it - even in the Peon 230! I can't bash it though, I mean it does flash with Betaflight, and "works" as expected, it's just not worth the hassle to me just to be old school cool... Eh, who am I kidding? I'll probably get bored and end up flying it in something anyway!
