What a difference a dynamic prop balance makes!!


Recommended Posts

I recently sent my 3 blade Hartzell out for inspection and reseal. They statically balanced as part of their service. They suggested I dynamically balance when it got remounted which I just completed. I was completely blown away what a difference this made. I literally can put a glass of water on my dash and there would be no movement. Best $340 I ever spent. Sensenich prop at KLNS (Lancaster) did the work and takes 1-2 hours. Great restaurant next door too.

Great Pirep, Charles...
Got any detail on the IPS, before and after?
Best regards,

I know what an IPA is. Heady Topper is my fav.

Not sure what IPS is. If you’re referring to how much weight he put on, all I can say is he screwed 2 different weights onto the flywheel and validated the results with a 2500 rpm run up. What I was told is dynamic prop balancing should really be referred to as engine, prop and spinner balance. A lot of forces at work. Another small point is if you loose a blade or otherwise get massively imbalanced. The vibration forces could literally shake a motor off the aircraft which would be a very bad day indeed. Probably not recoverable if airborne for obvious reasons.
