I have been offering my services for dynamic propeller balancing and vib analysis. I have a Dynavib GX2 (Vib Spectrum Analysis). I have the availability to do a standard dynamic balance as well as perform a detailed spectrum analysis of your airframe or engine. Since I am using the latest Dynavibe GX2, when finished you will see exactly the level of vibrations at start and where they are at the finish. No more guess work. At the conclusion, I can print out a data sheet for you to see graphically the work that was done and a log book sign off.
Statically Balanced is not the same as dynamically balanced. If you have never dynamically balanced your prop or you have not in a long time, you could be causing wearing your engine and airframe.
