What Would YOUR Plane Feel LIke After Using DynaVibe?

It’s been a decade since RPX Technologies began offering DynaVibe propeller balancing equipment to the aviation industry. In that time, we have collected a lot of data about the state of prop imbalance.  Our data tells us that about 80% of props are out-of-balance, and when they are dynamically balanced, owners, pilots and mechanics report that the difference is amazing.
 
What does it mean when we say that 8 out of 10 general aviation aircraft are flying with an unbalanced prop?  Technically speaking, it means that the measurable vibration exceeds .15 Inches Per Second (IPS), which is the maximum acceptable vibration level after dynamic balancing. We’ve seen vibration levels that are much greater, and the greater the magnitude, the more damage the vibration can do to the airframe, engine and instruments. 
 
Eliminating vibration is important just for the maintenance benefits alone.  But if that is true, why are so many airplanes flying with unbalanced props? The reasons vary, but often it is because of a false assumption that vibration is just the price you pay for having a combustion engine that turns a propeller at a high RPM, and therefore it must be lived with.  Don’t buy in to this false assumption!
 
We’ve seen many DynaVibe users eliminate vibration completely, or get it well below .10 IPS – a level of acceptable vibration.  What would YOUR plane feel like after using DynaVibe? The reactions and feedback we get from DynaVibe users that experience flight with a balanced prop answer this question. These comments have a similar theme, and we never tire of hearing them.  Here are some we’ve collected through the years:

• ​"Wow, I can't believe the difference! I didn't realize how rough my ride was, assuming that much of the vibration was coming straight from the engine. But, when Brian Wallis worked his DynaVibe magic on my prop, the airplane really smoothed out. Cross-country is so much less fatiguing now, and it's obvious that there's less stress on the airplane."

• “We recently had the prop overhauled on our RV-3, and that included new blades and some work on the hub—so I expected that we’d need to re-balance it...we borrowed a Dynavibe Classic from a friend, and hooked things up. Sure enough, we were off by 0.40 IPS on the first try—not horrible, shake your teeth rough, but certainly not where we’d like it. A couple of runs brought us back inside the generic target of 0.10, and since it was cold and starting to rain, we quit at 0.050 IPS. I took her out this morning for the first time since the weather had cleared, and the difference was once again remarkable! It’s the old (probably apocryphal) problem of boiling the frog—if you gradually turn up the heat, it doesn’t know that the temperature is rising. With a slight degradation over time, we don’t realize we are losing balance. Then we reset, and all the smooth magic is back!”

• "Before balancing the propeller, I placed my hand on the panel and could feel the airplane vibrating during the run-up. After only a SINGLE measurement and weight adjustment to the propeller based upon the readings and recommendations from the DynaVibe propeller balancing system, the vibration was eliminated. I couldn't be happier—the Dynavibe propeller balancing system is easy to use and very effective."

• “My RV6 is sooooo much smoother now. Even at the lower RPM's there is a big difference. The run up is so smooth now. The best analogy I can think of is like getting new tires for the car. Even though it did not seem real rough before, afterwards it is so smooth. I think I even gained 30-40 RPM on the top end.”
