I think you all know the problems I have had with this rum rum 912 I have.
I went to Aircraft Spruce's Open house last year and got a good deal on this
insulation (top one). I used 3/8 and 5/8 both on just about everything
inside, top and everywhere. Even put some directly under the engine. I
purchased a sound meter and started taking readings. I eliminated
approximately 15 to 20 db at my seat on the ground and in the air. I still
had that damned rum rum but it was not as noticeable and well within my
toleration level. Now, if the new muffler system from Aircraft Exhaust
works the way the man says it will (not much I can do about it if he lied),
I should knock off the harsh high pitches of the engine and bring it down a
notch to very nice and maybe, just maybe, the rum rum will not be very
pronounced. Gotta hope. Anyway, I am very happy with the insulation I
bought and think it did a splendid job. It was hard to cut but it stuck on
really nice with the spray glue type of adhesive I used. I would not pay
those other prices until I KNEW what it was and how it would work. 1/8 inch
of foam glued to the inside of your fuse will stop the drumming and 1/4 inch
of a rubber type of foam under the center gape will do the same thing.
Unless you just like to spend money, come on over Hawk and let me show you
the stuff I used. I have some samples left. Nice stuff. Ted Cowan,

My little sling shot 912 burns just a tad over 3 gals per hour at 4800/4900
rpm @ 85 mph. I am heavy for a slingshot, 500 lbs dry. My 582 would burn
from 5.5 to 6.5 gph at 75 mph loaded for Florida. I carry a tank with a
possible 9 gal reserve with electric transfer in my back seat plus luggage.
That is why I love my little bird with its 912. I am going to get rich just
flying it. Gotta wait until Tuesday to get my exhaust back. Will let
everyone know how it tunes out. Ted Cowan, Slingshot 912UL, zoom zoom.

Sorry if I'm coming in late on this one.
Don't get lulled into the "30 min reserve" will keep you safe! Been there, done
that, bent the gear in a hayfield in TX.
I was a heavy iron GA pilot and thought the FAA regs would keep me straight. Problem
is the regs were written for planes that have cruise speeds of 120 mph
plus. Planes that do 60 mph can't get as far as in 30 minutes. Throw in a little
wind in the wrong direction and your options start to vanish quicker. Next
airport just 30 minutes up the road can be well over 30 minutes with just a
little bit of the wrong wind. Don't even think about mid morning radiant fog
covering the airport when you get there.
Yes you do have a lot more options of off-field landings. Farmers around here
ain't friendly to ruining their cane fields. As wet as we have been down here,
you couldn't get in and out till summer.

Tom/list,
I have used the performance of the intercom as a measure in judging headse
ts.My 30+ year old David Clarks have a mike gain control (a small white pl
astic screw near the grill on my H-10-30s) that the nice lady at DC said
I could adjust to help stop transmitting cabin noise.I called them to see
if their latest mics would be better at controlling noise.She said I alre
ady had the best for this problem.I never noticed the adjusting screw,buri
ed under the foam cover and leather boot I had installed over the years.
Keeping the noise out of your ears with good seals ,DC makes some tapered
eyeglass frame seals for that too,and keeping the noise out of the microp
hone helped me the most.

Dear Kolbers,
I wanted to know your views on the performance of a Bose Headset
on Rotax engines in case anyone has used it.
I presently fly with a Lightspeed XC and it performs good both on
the Kolb and GA aircraft, but if the Bose is really quiet, I was
planning to upgrade. Any feedback is appreciated.
Thanks,

John,
If you equate 75% power as 75% carburetor slide opening, the 447 will be
running at max power. This is due to the fact that the Bing 54 carburetor
is over sized for the engine. I found that the 447 will top out at 6,200 at
about 34% with the throttle at the 34% position.
If you equate 75% power relative to rpm, then .75 x 6,200 gives a cruise rpm
of 4,650 rpm. From my flight log, I pulled out the data shown below. All
of these flights were from and to Perryville and Painton, MO. You will
notice that all of the rpms listed are greater than your 75%. The rpm/rpm
indicates that a different rpm was set from the to and return flights. This
difference as due to the gps indicated ground speed and the expected gps
arrival time. If I had a head wind, I would crank in more rpm, etc. to get
to the meeting on time.

Hello All,
I have some very old off brand passive head sets and do not want to spend the money
on a good pair. What I have done is purchased some $60 noise canceling earbuds
(Audio Technica) and that has worked fairly well. I wear them under the
headsets and I listen to the radio through the earbuds so the headsets are passive
noise reduction and mic. I recently purchased an intercom box so I am
going to try a different method of just using the earbuds for noise canceling
and the headsets for listening as well as talking because I now will have the
volume available in the headset. I am sure this is not as good a solution as
a good ANR headset, but you can definitely tell the difference between the ANR
turned on and off in the earbuds.

75%power would be a difficult measurement to acquire accurately. Static prop thrust
wouldn't even be accurate due
to inefficiencies with no forward motion. The only real way to do it would be
on a dyno with no prop.
If you had a magic strain gauge between the prop and hub you could get something
useful in flight.
On mine I just pull back a few rpm and settle for it.

It's all good. Finished getting the rust off the steel root rib for the left wing
and welded up the hole for the clevis pin. Can you believe it was wallowed
out to almost 3/8"? And somebody was flying it that way? So yes, there is more
than one way to fly an airplane, in the case of this basket case we bought and
cannibalized, by someone who apparently didn't mind rattling and flopping through
the sky... [Rolling Eyes]

My Firefly gets 2.5gph at 55 MPH turning 5300-5400 RPM. It's empty weight is
about 280 lbs (from memory; too lazy to get my weight and balance).
If Terry Franz is reading, I believe he's say's his 103 Firefly get's closer
to 2.0 gph, but he's done more optimization then I have.

I have a ANR kit that I added to my headset. It helps but I use Sony passive
ear buds under my headsets to get even more noise reduction. They also do a
much better job of sound reproduction than what I get with my Segtronics
headsets. I'm currently operating out of a airport where there is a flight
school staffed by instructors that use just passable English so the better I
hear them fewer times I have to ask them to repeat those runway numbers. I
have considered trying a set of those active noise canceling ear buds under
my ANR headsets. Hey it might help? If nothing else when the headset battery
craps out I would have a ear bud backup.
Don't under estimate the benefit of what you are doing. Like all aviation
products you have to pay for the lawyers and get very little if any benefit.
I'm also going to look for some of those eye glass bow seals for my
headsets.

I have a Bose headset. Picked it up at Sun and Fun a couple years ago in a weak
moment (they were throwing in a CD player for free, so my years of resisting
the temptation finally ended!) I paid them off over a year.
They're great in GA airplanes with Lycoming engines. They were totally ineffective
in the MK3 with a Rotax 912. John is right. Get the DRE's with active noise
reduction. We've got two sets in our Kolb and are very satisfied with them.
Have fun!
Dave

I have been enlightened.
Thanks, will try to explain the way I do it somewhat later tonight. Right
now it is time for the Atlanta Supercross Live. ;-)

Here is how I built my enclosure for a original firestar.
***************
The original Firestar top longeron was straight from one end to the other.
I noticed yours is drooped in the front, similar to the FSII.

Yes it is, I lowered the sides when I restored it for easier entry. Also did the wing mods with the alum angle/.035 LE & TE/wing tip mod/lateral bracing. Here is my site with photos of rebuild you can see all the the mods I did. www.brianskolbfirestar.comlu.com

Aha.... Larry
I did put a ANR in my Sigtronics. Oh I did misspell them. Se below.
They work very good.

Strangely to me at least, I get better performance out of a
Sigtronics S45 headset than I do from a DRE 6000 ANR. The mike is better
and easier to understand for my wife, on the base station. Has anyone
put an ANR kit in a pair of Sig's?

I have a ANR kit that I added to my headset. It helps but I use Sony
passive
ear buds under my headsets to get even more noise reduction. They
also do a
much better job of sound reproduction than what I get with my
Segtronics
headsets. I'm currently operating out of a airport where there is a
flight
school staffed by instructors that use just passable English so the
better I
hear them fewer times I have to ask them to repeat those runway
numbers. I
have considered trying a set of those active noise canceling ear
buds under
my ANR headsets. Hey it might help? If nothing else when the headset
battery
craps out I would have a ear bud backup.
Don't under estimate the benefit of what you are doing. Like all
aviation
products you have to pay for the lawyers and get very little if any
benefit.
I'm also going to look for some of those eye glass bow seals for my
headsets.

I fly the same headset as you; you will not find anything quieter. A
friend of mine who has to have the very best of everything thought that more$
= better. He bought that $1k Bose, then retired it for a QC.

I wanted to know your views on the performance of a Bose Headset on Rotax

I presently fly with a Lightspeed XC and it performs good both on the Kolb
and GA aircraft, but if the Bose is really quiet, I was planning to
upgrade. Any feedback is appreciated.

Wish I had had those mods on my FS wings 20 years ago next month. I might
still be flying it if I had.
They look good.
