Troubleshooting a Rotax 582UL engine vibration. I examine and describe propeller tracking. Follow me through my diagnostic procedure. See my blade pitch tool in action.
Nice video on setting prop and blade tracking. I've built a jig that holds a laser to the prop blade and projects a laser lite onto the wall maybe 20' away. Twist each blade so they all hit the same spot and it is super accurate. At 20', 4" equals about 1 degree. I usually get the blades within 1/8" of each other. Here is a link to the video I put up of it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-c9Uj_d3uSWc.html
