Thought for sure I'd just search thingiverse and find 15 options--but, no i guess nobody ever thought to make a pitch gauge like this for doing alieron, rudder, elevator measurements.

Sure, if your instructions give out mm/in deflection this is of no use. but, a lot of kits call for degrees of deflection.

Since you can only have 4 measurements per tool, here are a few options with different common deflections on them. print them all out and keep them in your bag. super simple and quick to set up your surfaces this way.
