ZMR250 Orientation stick

thingiverse

I often struggle to differentiate between my quadcopter's front and back while they're airborne. Each side seems identical, which makes orientation challenging for me. To alleviate this issue, I frequently attach a small ball to the leading edge of the quad so that I can clearly identify its forward direction during flight. I've devised several modular components that may be combined to form an "orientation gadget". The necessary components are some M3 screws and a suitable tube with a diameter of approximately 3.5 millimeters. My solution involves gluing together multiple shrink tube segments and placing them within a soda straw, creating a lubricated surface for effortless sliding into place. A fiberglass or carbon fiber rod would also have proven to be effective alternatives. In contrast to modifying the ZMR frame itself, my design relies solely on the existing holes to securely fasten everything in place. No further modifications are required. During transport, I carefully push the orientation rod towards the rear to prevent accidental damage; when flying, it remains fully extended and visible.
