To date I have not heard a good explanation as to the cause of the shakes. So far we only know that going to a 3 blade fixed it in every case. I'm jealous of those who have a 2 blade and no shakes.

I actually think this is an excellent discussion. Great feedback from those that have been there. No one so far has said that they had the shakes and changed isolator mounts. I am hoping to provide some data here once I work it out with Hartzell and Lord or Barry. Many thanks for all the posts on AND off list. Keep em coming.

I hope you can work out a good solution with Barry. The 2 blade propeller has a 2nd order harmonic that isn't present with a 3 blade propeller. That is the vibration you are trying to isolate. A 3 blade propeller has a 3rd order harmonic that isn't present with a 4 blade propeller. I'm planning to use the MT 4 blade Rocket propeller on my Harmon Rocket 2. I also have the Lord mounts.

Improving these airplanes isn't silly. If nobody bothered to come up with new ideas or improved these airplanes there wouldn't be HR2's or F1's or Super-8's. Or even RV's for the matter.
