Using any method desired, a length of tape can be fixed in almost any position and marked. It is easiest if the blade stop point is in the down position. Place a small length of tape on each blade 6 to 8 inches from the blade tip. This is the hardest Working area of the propeller. The stick is placed horizontal at the same height as the reference marks on the blades.
Place straightedge on reference stick and hold other end gently against prop blade.
Make sure that you contact the leading and trailing edge of the prop blade. At the position the straightedge will assume on the reference stick place a mark. Repeat several times to make sure that you are not placing any deviation on the blade. Make sure the measurement comes out the same each time. Choose any blade as your Master blade then repeat the same setting procedure on each blade adjusting each blade to the same setting as the Master blade.
