RC Helicopter Pitch gauge
thingiverse
Made a holder for my ebay/china level box to set pitch on my RC helicopter. You might have to sand the sliders if your printer is "sloppy" as I made it thight fit to not wobble when measuring. Could prolly be better but I mocked it up quickly just to set my pitch. Use a rubber band against the senter notch to make them slide in and grip the blade. I didn't complete my heli setup yet so for all I know this thing doesn't even work but it seems to be working for me :)
