I'm almost sure the vibration is coming from the prop and it could be a accumulation of moisture and I also understand I should not be running a 20 year old prop. Just finishing building this bird and wanted to see it run before I spend more money. Heck, after ground run for 20 minutes I had to pick up screws and washers it shook out of the plane. Don't think its quite ready to fly yet. Say, this could be a new way for an annual inspection. Bolt on an out of balance prop, run for 20 minutes, if nothing falls off, your good to go for another year! LOL
