I'll try your method too Kelly. i'd like to try different tensions to see how it affects noise. I actually "saw" the infamous rum-rum noise (as described years ago on airsoob) on my plane. I saw the prop flexing forward and back (coning out) and kindof wobbling in a 1 second or so interval. the sound matched the prop wobble. not sure how 2-blade vs 3-blade, cowling shape, belt tension, etc add up together. gary
