Heli Blade Pitch Gauge

thingiverse

To measure blade pitch using an iPhone 4 without screws, print heliLevel1 and heliLevel2 and slide them together. Use a preferred level app from the store; the gauge may be slightly loose but can be shimmed with paper. Secure the slide using a rubber band to hold the blade in place. V2 files include upgrades for rubber band locks, eliminating the need for shims. Print V2a, V2b, and V2c for full replacements or use originals if preferring simplicity. The last two photos show V2 design in action; hopefully, someone finds these useful.
