Here is my SlowStick with the carbon fiber arrows. One of my first planes was the original SlowStick many years ago. Your twin arrow SlowStick got me interested in them again. You also got me into 3D printing. I now have two Creality printers and one Bambu printer. I also make Eclipson 3D planes. The plane in the picture has DJI FPV gear. I use AutoDesk Fusion to make my own simple parts. Thanks, Dave, for pointing me in this direction.
