Would that be the local Lion red. You will be the center of attraction
in Russel next week. Waitangi day Saturday. You are in a good place to
see how well we all get on in this country. As you probablt know
Waitangi is gust across the bay from you. It is a lovely place .Enjoy
your visit. to keep it Kolb related ,I headed off into the wild blue
yonder on Sunday in the MK111c ,15 minutes later I had had enough of up
,down, side ways so returned to tera fima , went home and had a beer or
two . Lots of thermal activity, plus they just made my local airport a
mandatory radio operation,I have been flying inaudo from there for close
on15 years and radio was playing up. Thought I had better play by the
rules since they are new.

safe flying

Hi Russ,
Not into the various grades of Loctite and a long way from home
at the moment.
I am sure that a post to the British Microlihjt Association
website with an ask for help someone would give you a steer.
Made it to the Bay of Islands 2 days ago after good time in
Cambodia and Laos.Pretty much bushed at the moment as I have had to get
the cushions for the sunbeds
and lay them out on the deck which surrounds the bungalow. Sea
is about 20ft5. away. Nice gentle waves. Weather warm wind 5knots. .I
think I will get a beer.

I dont really know what you guys have for dynamic balancing but let me tell
you this story. I (we kolbers) figured it was the blade. Not faulting
anyone but the warp I had was three blade and was not very matched. Warp
made and sent me another one which was very very good. I have a model
airplane blade balancer (big one) and balanced it real nice. I also put it
on a center line balancer and it came out perfect. I use a laser to set my
blades to pitch. All this made it a lot quieter. Was worth the effort. I
also put a whole different blade set up on it complete with hub. Less blade
noise but still had the rum rum. Now, at this point I want to say there is
little or no vibration in the cockpit or on the airframe itself. Nothing is
vibrating. I feel very little in my stick. (a lot less since the new
prop)(thanks warp drive). I think I am going to actually take the wings off
before I load it to take it where-ever, probably Ronnies. That would
definitely prove it is not wing born. By the way, has anyone ever put the
spray in foam into the wing panels close to the root through the inspection
holes? I was thinking of that to quiet any vibration in there. That stuff
is light and tuff. When I turn the prop, the resistance I feel in the
engine is just probably normal stuff but I wanted to mention it. Cant be
anything really sever cause I havent had a moments trouble with the engine.
Everything else is just perfect. Talked to Lockwood Av. and they want me to
try another set of gears and see. Boy, would I like to go to Sebring Fl and
have them put it on their special noise evaluator what-ever that is. Long
trip, almost 600 ms from here. Anyway, thanks for the help. I have learned
an awful lot about my engine chasing this noise. Had to have everything
perfect to chase it. I laugh at all you guys worrying about how much drag
with engine out. he he he. Fly a Slingshot and you wont worry. There is
no glide path. What you see just below your windshield is where you are
going to land. Nose it down hard as you dare, keep up about 60 mph airspeed
and one flare only. You are down in about thirty feet rollout. Someones
backyard is big enough. (watch out for the slider and swings) Enough.
Take care and thanks. Ted Cowan, Alabama, 912UL.

Ted=2C
Although the foam might be a good idea=2C you do have to be careful. The
re are 3 grades of the stuff (at least three that I know of). The grades v
ary by how much expansion pressure they have. The weak grade is for window
gaps=2C etc. It doesn't distort the structure. The strong grade can and
will spread apart the structure gap=2C like in a door frame gap. It can ac
tually ruin the door fits to where it won't close anymore.
If you were to try using this foam=2C I'd recommend the middle expansion
foam=2C and try it in a test area first. It would not be wise just to star
t spraying blobs of foam everywhere=2C only to find you've now got wings wi
th bulgy muscles. :-(

I was only addressing the expansion aspect of the foam=2C but I think you
have a good point there.
I think it is probably best to leave the foam to Obama's green weatheriza

Why do you have to reseal your gearbox?
Is it leaking, or is this a documented item of 912 maintenance?

This engine has always had an tiny ooze, first at 8'clock and now at
4'clock. The 518 did not last, the 5910 lasted a little longer, and
maybe some of these new sealers/gasket makers will get the job done.
The casting in the area of the flanges on the gear box and engine cases
are not perfect, looks like it may have had an inperfection in the area
of the leak. One that slipped past the inspectors. Nothing serious,
just a little oil on the engine type of thing that is not normal on a
912. I get more oil on the engine from the crankcase breather than I do
from the leak.

Ted -
Have you tried a two-bladed prop?
That may eliminate the "fourth harmonic" which Lucien spoke about.
As one who also suffered the innocuous, yet damaging, effects of
harmonics from a specific engine/prop/airframe combination, I sympathize
with your situation.
(My solution was: I ended up switching engines.)
Just a thought ...

Hi John H.,
Your gearbox shouldn't ooze. I clean both mating surfaces with a scotch pad and
lacquer thinner. Then I apply a thin coat of 5910 (Permatex "The Right Stuff")
to both surfaces, but not so much to cause globs of it to squish out the sides.
Never had one leak yet. (Knock on wood)

Roger L/Gang:
Yea, I know it shouldn't leak, ooze, drip, or seep, but it has since new.
My first two never leaked, but this one does. Hopefully the new sealers
will work better. I hate leaks. However, it is more cosmetic that an
operational problem. Never have to add oil between changes. Not a
something critical or catestrophic.
I clean up the flanges too, so did Ronnie Smith. Make sure there is
absolutely no oil residue on them before sealer and replacing.
If The Right Stuff doesn't work, I betcha the Yamabond or Hondabond will.
We have put two and four stroke cases together with it and never had a
problem. Back in the old days before Yamabond and Hondabond, we used 3M
weather strip adhesive, commonly referred to as Gorilla Snot, because of its
color and tenacity. Bringing back some old memories now.

Hi Ted,
You have been dealing with this rum rum noise for quite some time now and
I think I've read that you have already performed carburetor synchronizing.
When I rode motorcycles, riding alongside of another cycle, I would hear
this kind of rum rum noise. Two engines out of sync. Do twin engine
aircraft make this noise if the throttles are out of sync?
The Rotax 912 is kind of like two separate engines in a way (with two
carbs feeding separate cylinders, separate exhausts, etc.) and just maybe this
could be a factor.
Anyway, I do hope you find the answer sometime. Keep on keeping on.
