The Affordable Dynamic Prop Balancer
Proviation is pleased to be a UK agent for
DynaVibe; the economical, state-of-the-art dynamic propeller balancer
designed specifically for the aircraft industry.
DynaVibe displays the magnitude and phase of propeller
vibration allowing precise weight adjustments for balanced and smooth engine
on your engine, airframe and passengers, for a smoother, more
Economical - including:
Accelerometer with 30 ft cable
Optical Pickup and Reflective Tape
No hidden costs or additional items to
Accurate - Reports RPM, Vibration Magnitude

Revenue for your business
Dynamic propeller balancing provides an additional revenue stream
for your business. A typical balance takes a couple of hours, and just a few
run-ups. Make hundreds of pounds on each balance job. DynaVibe pays for
itself with just a few uses!
A properly balanced
engine installation offers a number of advantages over unbalanced equipment. The
most significant advantage is in the longevity of components associated with the
In many cases high
vibration levels have lead to premature failure of critical engine components.
Engine accessories, engine mounts, firewalls, and instruments are also
susceptible to vibration damage and premature failure.
"I flew down to
Brown Field to get gas this afternoon and the improved smoothness is apparent.
It hums in a way that it hasn't up until now. This is apparent not just at the
full throttle RPM that I optimized it for, but throughout the RPM range. I
pulled it back to 2400 RPM and just motored around the local hills &
mountains as the sun was going down, enjoying the smoothness."

“Our company produces high performance Turbine and piston powered
aircraft with speeds that easily exceed 300 knots.We needed a precision dynamic
prop balancer that was simple, quick, easy to use and affordable. We found that
in theDynaVibe. The DynaVibe has now enabled us to extend our business services
to include dynamic prop balancing for allpropeller driven

Piper thought of Dynavibe here
Q: Can the
DynaVibe be used on geared prop installations?
actually works very well on geared assemblies since the geared drive puts the
engine vibration frequency at a different frequency than the prop vibration
frequency. This makes it easier to isolate just the prop vibration.
the DynaVibe work on a 3 blade prop?
number of blades on the prop is irrelevant in the balancing process.
the DynaVibe be used on rotorcraft?
A: Sure! The
rotorcraft version of the DynaVibe Balancer includes an additional accelerometer
and remote averaging button. Note that we're not rotorcraft experts so we can
not offer technical support for tracking and balancing a rotorcraft other than
how to operate the DynaVibe itself.
Q: Can the DynaVibe be used with
turboprop and radial engines?
Everything focuses on the prop assembly. It doesn't matter how the prop is
driven. We have many customers using the DynaVibe on turboprop aircraft.
Regarding radial engines, the orientation of the cylinders is cause for concern
since vibrations from combustion are in the same direction as the prop
vibration. However, we've had several customers use the DynaVibe on aircraft
with radial engines and it worked well.
Q: How do I mount the accelerometer
and optical pickup?
A: Due to the
variety of engines, we're not able to supply mounts to fit every configuration.
You will need to build a fixture to bolt the accelerometer and optical pickup to
the engine. Typically, the mount is bolted using one of the case bolts. The
accelerometer is mounted on the bracket in the vertical direction, and the
optical pickup is pointed toward the prop, near the hub.
Q: Can the DynaVibe
be configured to read where to add weight instead of where to remove
Simply mount the accelerometer upside down (with the cable pointing toward the
Q: Should the
reflective tape be removed from the prop after it is balanced?
A: It takes a
very small change in weight to cause an out-of-balance. Since the prop is
balanced with the tape on, the tape is usually left in place to maintain
balance. Note that some people do prefer to remove the tape from metal
propellers to avoid corrosion.
Q: How can I practice using the
A: It is very
helpful to practice by balancing a box fan. You can drill small holes and attach
small (i.e. #6-#10) bolts to the fan blades to see how the DynaVibe
Q: What can be causing the DynaVibe reading to fluctuate or give
* Hold RPM as stable as possible when balancing.
It will take several seconds at a stable RPM for the reading to
* The engine should be running smoothly from
idle to max RPM. Don't try to balance a prop with a rough
* Route all of the DynaVibe wires well away (4" or
more if possible) from spark plug wires or other sources of electrical
* Make sure there are no loose components on the
engine that can be moving, such as the spinner, magnetos, exhaust pipes,
* Keep the accelerometer mounting bracket
as short and stiff as possible. If the bracket starts to resonate, the magnitude
and phase angle will be affected resulting in an incorrect
Q: What RPM
should I use to balance?
A: The best
readings can be taken at cruise RPM, or the maximum stable RPM safely
sustainable for one minute.
Q: Does the DynaVibe tell you how much weight to
A: No. Every
ship is different. You will get a feel for how weight affects the IPS reading
after your first measurement, correction, and subsequent reading. For example,
if your initial reading is 1.00 IPS and one washer reduces the out of balance to
0.75 IPS then you know that one washer corrects 0.25 IPS. Therefore, it will
take an additional 3 washers to balance the prop assembly.
Are the DynaVibe accelerometers fragile?
A: No. We
make our own accelerometers using state-of-the-art sensor technology, not piezo
crystals. DynaVibe accelerometers are quite tough and will not be damaged by
normal handling or drops. While it is possible to crack or chip the sensor's
epoxy housing, we have never had sensor failure due to accelerometer mechanical
Q: What does the angle measurement mean on the DynaVibe
A: The angle is the location where the prop assembly is too heavy. Either
remove weight at this angle (measured from the master blade in the direction of
prop rotation), or add weight at the reading angle +/-180
Annual Collect and Re-calibrate
We recommend an annual recalibration. This service costs £94.00,
and can be purchased via Proviation online. We will send you a reminder nearer
the time that you may need to recalibrate. We will arrange
collection of your unit for re-calibration!
