I put some Dynamat Extreem sound barrier on the fuse between the ailieron
push pull tubes. Worked well. Another option I tested is to hang it from the
lexan piece that sits behind you. I can send photos if you like contact me
off list.

I love my Kolb except for the noise. I am
| thinking of building a flying trailer and putting the engine back
there.
Hi Folks:
Remember! As long as it is making noise............. the engine is
running.
Also! Gliders are great at low level flight............ for a few
moments.
Take care,

Just food for thought... Are you sure that all that noise is exhaust noise.
My direct drive VW made enough noise to wake the dead so I added a muffler
and a nice four into one exhaust system where I had four separate unmuffled
pipes. It made no difference. When I switched to a redrive the noise got
MUCH better. Then I got wondering about the muffler so I pulled it off. The
noise stayed the same and the power went up. My conclusion was that the
noise was prop noise.
When I reworked my motor mount to lower the engine the noise came back big
time! Now I think the noise is from vibrations that aren't being dampened as
well by the new mount. The new mount uses Lycoming bushings as vibration
dampeners and they don't work as well as the Lord dampeners that Kolb
supplied. I'm tuning the bushings and looking for softer ones.
So from my experience I would suggest you look at reducing vibrations being
transferred to the airframe and look into sound deadening. David Key has a
suggestion and a product that might help both of us. Dave would you share
your photos with all of us?

Denny,
Believe it or not, Luray wants to go to a powered chute. Talk about a
180 from where he is now! I can't quite believe it myself, especially
knowing how much care and pride he put in to building the SlingShot.
Different strokes for different folks!

Don't worry about it. I'm switching from a powered parachute to a Kolb, so
the Universe will stay in balance. ;-)
PPCs have their points. I flew one for five years. But I'm ready for
something with a little more range, speed, and wind resistance.

I decided to have my engine outside the cockpit. I made a fire wall
under the engine and covered it with sound isolating fire retardant
foam. The gap sill comes to and attaches to the fire wall.

Here is a technical question. I love my Mark III Classic. BUT, it is
noisy. I use a Geo Metro engine which is great, but still noisy. I
have heard that if one cuts a slot in the after part of the exhaust, it
will be quieter. I now get 270 lbs of thrust at 5000 ft density
altitude which is about 325 lbs at sea level. I will be trying this
slot soon along with a thrust test to see if there is a difference in
noise and in thrust. Has anyone ever tried this on a four cycle engine?

First the sound proff(SP) stuff is heavy-thick rubber like.
I bought the stuff and folded it over once, put in in my sling seat taped it
over my head. Took off and flew for 10 minutes, then reached back and pulled
the stuff off and there was a big diffrence!!
I put it on the back and put it on my lexan thing.
I'm sure the prop noise was a major factor, so I covered the gap in the back
it was open before. That hole in the back was acting like a giant megaphone
through the cockpit. I was most impressed most by the pieces hung off the
lexan. It works great. It puts the SP right behind my head and goes down to
my mid sholders. It folds against the sides and really works well. I have to
pieces of SP stuck together and the lexan is in the middle. I can really
notice the diffrence and I think the tower can too.
I won't win best looking plane at the next flyin but I'll be able to hear
who does.
(EMail me for pics.)
I got it on Ebay searh for "Dynamat Xtreme Extreme BULK"
I got one 32"x18" Sheet 4 SQ FT, one sheet is all you need.
It costs me $14 plus shipping, all you need is one sheet.
