Auto Credit Based on LofiTurtle's PID controller 3.4

This is a quadcopter* drone with a complete flight controller made in Vizzy (*it will have real propellors when they exist in-game). The flight controller handles all the engine throttle values, so you only need to control roll & pitch angles, yaw, and altitude.

Roll / pitch / yaw / throttle to fly. The default mode limits maximum angles, but AG 1 enables acrobatic mode, so you can fly it more like an FPV drone. (Setting a higher FoV can make acrobatic mode easier)

My eventual goal is to get multiple of these to fly in formation, or to have them follow an aircraft. Formation tests with simpler vehicles are looking promising, so expect more cool stuff soon!

    @Gozinya Thanks! the program is on the block the chip is mounted on, I needed to move it and change the xml in order to get more commands per frame. And I didn't know there was a discord, can you post the link?
    Edit- I found Simplerockets chat, I assume that's the right one?

    Also, you should join discord if you haven't already (couldn't find you with this username). I think you would like the Vizzy channel, and could add some serious value there.

    Funny, we both made drones at the same time! I really like your control scheme, and the way you designed this. I looked around a bit, but couldn't find your flight program. Where is it stored?
