3D printed 3" Whirlygig tricopter by 1Smug_Bastard using PLA and an Ender 3 Pro. Choose your flight controller carefully. I wasn't able to get DRonin to work with this stack but BF 3.2.2 out of the box works well enough. It's so small I don't know if I miss the Auto Tune and Servo Calc functions in DRonin. Working on a remix with integrated prop guards. I should have used a smaller VTX but its what I had lying around.

Another remix with prop guards.
