Bobby Hester came down
to KLUG and balanced my prop after I re-clocked it and got it down to 0.03
ips...it's smooth as butter now...I recommend everybody getting it done...
Thanks Bobby!!... Mike Kellems RV3 N74TX - Lewisburg, TN
Thanks
again for balancing the prop on my RV6. I have always wanted to have
a prop dynamically balanced just to see what kind of difference it made.
I could not be happier. The run up is so smooth now. The
cowling does not shake like it did before. What a difference! The
power comes up so smoothly now it's amazing. I didn't think it was
very bad before but it so much quieter and smoother now. The power
seems to come up faster and smoother on take off and I believe I see 30-40
more rpms. The closest analogy I can think of is putting new tires
on your car. Over time you get use to the not so smooth ride but as
soon as you install new balanced tires the ride is amazing. It is
like getting a new car. My RV feels like a different plane.
Your balancing service is worth every penny just for the increased
comfort. Mike

On the initial run up we found that Mike's
plane had a 0.42 ips vibration reading. I made the first weight correction
and got it down to 0.33 ips. After the second weight correction, I got it
down to 0.04 ips, and we were done! While we were doing the run ups we had
two people holding the tail. After each weight correction they both said
that they could tell that there was less vibration as did Mike while
sitting in the plane. I
flew my RV-3 today for the first time since your prop balancing on
Saturday. I am very happy to report that there is a noticeable change in
the engine's smoothness and audible harmonics. I am very impressed with the
changes. Thank you for ALL your wonderful work!!! Charles

I
have to say the dynamic balance made a (measurable) BIG
difference. En route to DLZ prior to balancing our prop/engine, my
state-of-the-
art vibration instrument (piece of safety wire clamped to the instrument
panel) measured 5 to 6/32" vibes at 8500 ft, 2350 rpm. After balance
adjustment, I measured 1 to 2/32" at 7500 ft, 2350 rpm. I also
checked at 2400 rpm and the reading was 2/32" vibes. Even at
2500 rpm the reading wasn't much worse than 2/32". Previously
on other flights I remember cruising at 5500 ft, and 2400 to 2450 showed
3/8" yes 12/32". Needless to say I haven't cruised above
2350 rpm since this new prop was installed last summer. Thank you. Brad&Carol

Well gang if you haven't
got your prop balanced I suggest you reconsider. Bobby Hester did a great
job on my prop as I could feel the difference even while he was making
adjustments on the ground! I
ended up at .07 imbalance which is about as good as it gets and the flight
back to 10G was smoother than a politician's last lie! Thanks
Bobby for your time and effort.

My 4 was
noticeably smoother on the flight home. Thanks for accommodating my
schedule - time and $ well spent. Flint Brady RV-4 N954RV - Mt. Royal
Airpark - Crescent City, FL Flint's
plane started out at 0.49 and it took me a while but I got it down to 0.07
Today I did a prop
balance for a buddy who has a RV7A with a Mazda Rotary engine. We started
out with 0.40 ips and I got it down to 0.06 ips. His engine has a
reduction gear so his engine RPM read out is about 5800 but his prop RPM
was about 2100. 
I
flew Sunday, there is a tremendous difference. I have been doing
alot of reading on the pros and cons of Dynamic balancing and since you've
done my aircraft I cannot think of one con. It has reduced my airframe
vibrations significantly and as far as I am concerned extended the life of
my aircraft, thanks again and hope to see ya at some fly-ins.

We are very happy with the fine prop balancing job you did for us using
your Dyna Vibe equipment. We no longer have vibrating door handles and
there is much less cockpit noise during taxi, run up, climb out and cruise.
This made a big difference for our simple painted interior, even with
Lightspeed Zulu ANR's. Our IPS reading started at .24 with a factory new
IO-540-D4A5 engine/Hartzell CS BA prop combo. We are now at .01! We will
highly recommend you. Thank you! Wayne & Darlene Gillispie
N715WD RV-10 - Portsmouth, OH Today I did
a prop balance for a CFI that saw my website and wanted to get rid of some
vibration in his newly purchased Piper. Justin Kunz flew over from
Carbondale, IL. His plane started out at 0.62 ips and when we were done it
was at 0.07 ips. Here is what he texted me on his way home:
Can definitly tell the differance, I can read my Garmin 396 with ease now
on the yoke! No more oscillation!
Today I did a prop balance for a Buddy that has a differant plane every
other year. I think I've done about four differant Prop Balances for him.
This time it was for his RV4.
It started out at 0.63 ips and when we were done it was at 0.04 ips

Today I did a prop balance for a RV8
flyer from Collierville, TN. Here is what he posted on Vans AirForce
website:
Folks, if you haven't had your prop balanced, you need to. I flew up to see Bobby this morning and when I left he had it perfect. I mean 0.0 IPS
- It took 4 quick runs and when we did the last run, I could tell a big
difference before I even asked him how it went. He smiled and said zero...
On the way back home, it was smooth as butter. Well worth the time and
money! Mark Dickens RV8 - Collierville, TN (KFYE)
