*Note*: It is best to drill propeller from the back face. Back out drill several times as you go to clear wood from the bit to ensure a smooth, accurate hole. Do not force the bit through the prop. Place bolt in first hole after drilling to help with alignment when drilling other holes. Please always orientate the prop with blade tips at 9 & 3 o'clock or horizontal to the ground with the compression stroke before drill. In case of dead stick landings this can save your prop and your airframe.
