Homemade Incidence Meter

Here's an easy to make meter to determine incidence.  Made from scrape balsa so whatever you have laying around the shop will work. 

Make a copy of a protractor scale and just make sure you have it mounted square on the vertical.  Make the sliding arms long enough to clear the wing and the beam long enough to span the chord of wings you will measure, add a little more for good measure...who knows you may decide to build a Jumbo class rubber powered model. (I heard one fellow call it a "walnut" scale) 

Here's a drawing...just remember that the protractor scale will read 90 degrees for zero degrees incidence.
