I have a vibration I?m tracking down. While I?m investigating the usual suspects, thought I might ask your thoughts on this possibility. Might be dumb but thought I?d ask.
I have about 15 hours on the aircraft. Initial flights were smooth as butter. Carbs are balanced, prop is tracking and set accurately. The vibration is most noticeable through the stick as if it?s a control surface issue.
Level cruise, 5000 RPM. Didn?t have that until recent flight.
So here?s a thought: the earlier flights were conducted in cold weather and I never had the cabin vent open. Could an open cabin vent disrupt the propeller slip stream in such a way as to effect the elevator and/or rudder?
