Bristol replied that they had designed a catapult to could throw

Was attending a fly-in somewhere some time ago, with my trusty ole Original
Firestar (makes it kolb related) and a fellow told us this story: He was
transferred in the military to Alaska and took his family. Christmas coming
and being from the Northern USA, he and the family cut themselves a purty
Christmas pine for a Christmas tree in their home. Took it in the living
room and set it up with lights, etc. Really beautiful he said. Next day
the house was full of bugs; big bugs, little bugs, muskeetoes, biters,
crawlers, everything. A big mess. Seems that all those critters nest in
them there pines during the winter and they thought they woke up in the
bahamas or something. I guess you should check with the natives before you
take up a tradition in a strange place. By the way, Neilsen is right about
the biters in Michigan, lived there for over thirty seven years before I
escaped. ted cowan alabama slingshot 912 u.

Hi Vince,
No, but I was Secretary of the British Interplanetary Society Branch in
Bristol and a number of our committee worked at British Aerospace or
whatever it was called then and that kept me in the loop to some extent.
I live about 30 miles from Filton and I remember the Vulcan that had its
bomb bay fitted out as a test bed for the Concorde engines growling
around the sky locally.
I was on the beach near Weston super Mare as Concorde banked at the end
of her final fly by circuit before landing at Filton for the last
time. There was not a dry eye in house, she was soo beautiful and we
shall not see her like again.A sad end to a marvellous chapter in
aviation.
Thankfully I was lucky enough to fly in her 3 times. Once to Egypt, FOR
THE DAY, how cool is that, and twice to the States. The cheer that went
up as the Machmeter on the bulkhead in the cabin clicked up Mach 1 and
then Mach 2. Great memories
How about your story of flameouts at 58000ft. Thats got to be good. If
you don`t think it appropriate for the list try pj.ladd@btinternet.com.
I would really like to hear it.

Generally speaking gear redrives are a better long term solution and
driving the prop off the flywheel end of the crank like the engine was
designed to drive a car just seems a better idea.
The down side would be:
1 How many are there in operation are they reliable?
2 How well is the vibration damper tuned.
3 The Kolb engine mount would need to be modified to mount the engine
turned 180 degrees.
4 The VW engine is a bit heavy and gear redrives are heaver.
5 Cost?
6 You are the test pilot, I'm done testing new redrives.

My firestar2 has only got 75 hrs. on it. Today I took the bolts out of
the universal joint at the
rear of the wings. I was shocked to find that one of them had a ring
about 1/32 of an inch
deep worn around it. I don"t know why only one bolt was worn and the
others were ok.
Maybe it was a little to loose, they have to be loose enough for the
universal to work.
At any rate with another 75 hrs. ti would have worn enough to be
really spooky.
Anyone else have this problem? I will remove and check ALL airframe
bolts at my 100 hr. check.

Probably the cad plating was worn off. I'd have to go do some research to
find out how thick the cad plating is on aircraft bolts. Its on there to
lubricate and protect the bolt, self sacrificial.
I don't fold, so all my bolts are snugged up tight. If I did have to fold
each time I flew, I think I might snug up the bolts prior to flight, then
loosen them up a bit to fold.

Hi John,
The wear is much deeper than the plating.I do fold every time I
fly,It's a lot of trouble
but fits my budget better than hanger rent. It's also rough on my

Its a real good idea to check all bolts and fittings that could wear with vibration.
I put Mobil 1 Synthetic grease on all bolts and fittings that move against
each other. This grease is hard to find, but its worth the effort, its far
better than any other grease I have ever used. Some will say that grease
will attract and hold dirt, which is true. While not perfect, my greased joints
have not worn all in just over 200 hours. A greased fitting, even though not
perfectly clean is far better than metal vibrating against metal. Where others
have been getting wear, I do not get any.
There is the added benefit of zero corrosion in these areas also.

Yes, zero corrosion in my greased joints. I don't know why that seems hard to
believe, grease is an excellent, think corrosion preventative that is thick and
does not evaporate over time like many of the light oils do. If you have doubts
as to if it works or not, try it on one elevator half pivot bolt, or other
high wear area, and leave the other side dry, and compare your results after
the next 100 hours.

Sorry, jetpilot, my mistake.
When you said you had "zero corrosion" I assumed you meant no
corrosion anywhere. Obviously there'll be no corrosion under a film
of grease.
I still recall the endless polishing by the guys who had polished-
aluminum Cessnas -- even many miles from the coast.

Bill:
Believe it would be the choke piston and seat seal, or something like
that. Would have to look it up in the parts book.
They seem to fail with extended time, or did back in my day.
Another reason for not wanting to idle normally, is an engine that is
not operated normally. If you only run it on the ground, never going
full power or cruise power, the engine (crank case) with load up with
excess oil. Causes irratic/poor running and a lot of blue smoke.
If you are running rich at idle, it should probably blow black smoke.
I'm not too good at two strokes any more. Hardly ever operate one
except my chain saw and weed eater. For some reason they don't seem to
have all the problems the Rotax two strokes have.

I never actually pulled the bolts on mine (I hope Bob does at some point), but
I did at one point pull the joint apart to troubleshoot the little bit of slop
at the channel bracket where it bolts to the frame.
That whole joint is well designed (IMO), but is fairly low tech. It doesn't have
to be high-tech because it's not a high speed or constantly moving joint, but
it can eventually start to wear if you fold the wings a lot.
If the bolts are that worn I'd also check for slop at that channel bracket, as
if it gets too bad it can change the AoA of the wing panel slightly. The original
builder of my plane used shims of some kind under the channel bracket to tighten
it up (he folded it all the time too).
I'd treat the bolts and the channel brackets as consumables if I folded every flight
(i.e. I'd have spares on hand and would replace on a regular basis)....

Frank,
Steel on steel is not good. I have had a similar problem with my FireFly.
I solved it by bushing the holes. See:

Most likely the idle jet is plugged. this happens over time easily on the bing
especially on the 2 stroke if you let it sit for long periods of time. This blocks
off the airflow through the jet and makes the thing run full rich at idle
no matter how much you open the idle mix adjust screw.
If the choke weren't sealing right you'd have a more extreme version of that, up
to and including 4-stroking or even 6, 8, 10 or more -stroking as you approached
full throttle.......
Don't ask me why I know that......
Pull the choke plunger and check the rubber stopper at the bottom. If it's really
hard or chewed up replace it. Just an impression on the surface is ok.
Check the action of the choke and make sure the plunger seats fully by itself when
you close it with the lever. I.e. press on top of the plunger.... Any drag
in the choke system can cause it to hang open a little bit, which can be a BIG
eye opener on takeoff....

Cad plating is at most .0005" thick, according to the MIL-Spec... Frank
said his bolts are worn 1/32" (.03125"), which is sixty times more than the
plating thickness.

The amount of wear from folding (1/4 revolution each fold) is probably
insignificant compared to wear from vibration and changing flight loads,
unless something is way too tight or binding badly.
OTOH, the looseness required for folding allows more motion (and thus wear)
than tight bolts.

Bill, what rpm are you trying to idle at? 2-strokes don't idle smoothly at
low rpm's, and if you try, the vibration can cause havoc with the float and
needle, letting too much fuel through.
How's the rebuild going? You going to be ready to fly it this year?

- I pulled the choke stopper, and cleaned a bunch of soft brown goo off t
he bottom.- Apparently, that was the gasket.- When it was clean, it was
metal to metal.- I am getting a kit and choke parts in, but I was wonder
ing whether that would do it.- It has a very rough shaking from idle (200
0 rpm) through about 3500 rpm.- It smooths out at higher rpms.- Smokes
quite a bit when it's doing it.- I found a lot of brownish goo in the mai
n jet, and a small blob in the bottom of the bowl.- Ran a lot better when
the main was cleaned.- Prior to cleaning it was not running without a li
ttle choke, and now runs but shakes.- By the way, the air screw adjustmen
t made no difference- that's why I took the choke apart.-
-- I am not planning on having the Firestar ready this year- I am going
to take my time, and even if the plane is ready I am not.- Lessons will
come after repairs, and-I want them fresh in my head when I am ready.-
Also, my money has been going to-my kids lately.- They can spend it fas
ter than my retirement can pay for it.- I am having fun working on it any
way.

- John- It does look like blue smoke, which clears up when run over 5000
rpm for a bit.- I am not doing any extended running at all, but adjust, r
un, shutdown, adjust, etc.- This shakes a lot more than others I've seen.
- A carb kit won't hurt.- A friend says it needs to be run hard to blow
out the oil, but I want the goo out first.- You are right about 2-stroke
s.- My chain saw and brush saw don't give me trouble like this.- Fresh
gas usually fixes them.

Yes, even with powder coating, the rest of the airplane requires some attention.
There are some areas where I have had to remove the powder coating where it
gets chipped, or for whatever reason has not sealed well, and sand off the corrosion
and use Epoxy Primer. Corrosion X helps with the inside of the boom
tube, and I will be putting Corrosion X it in the wing spars for the first time
soon.
Fortunately, I am in an enclosed hanger which helps a lot. A Kolb left outside
here would not last long :(

Subject: | Tweaking the Warp Drive |
Installed new blades on my mkIII, 71" tapered, nickle steel leading edges,
yesterday.
Changing from 70".
Test flight yielded 5400 rpm WOT straight and level flight. I knew it was
going to be a tad over pitched before I took off. Was looking for 5500 to
5600.
Flew great, even though not quite as brisk as I like it.
Today, pulled 1 degree of pitch out of the blades. Used the Warp Drive
Protractor to do that on one blade. Then adjusted the other two blades with
a laser tool provided by Scott (icrash). It worked great to get all three
blades reading off the same sheet of music.
My field elevation is 410 msl. Pulled 5400 rpm climbing out. Engine felt
brisk. Climbed to 5,000 feet msl. At 5,000 feet the 912ULS was turning
5,300 rpm, climbing a steady 1,500 fpm with me (200 lbs) and 15 gals (90
lbs) of fuel, at 45 mph indicated. OAT was 40F at 5,000 feet.
WOT straight and level at 1500 feet yielded 5,600 rpm. I am happy. The
engine and airplane seems much lighter when freed up a bit, rather than
overpropped. Cruise seems to be about the same, 80 to 85 mph, at 5,000 to
5,100 rpm.
Now, when I head out West, I'll have a good responsive combination to haul a
lot heavier airplane at much higher altitudes.
Did not experience any abnormal operation with the new blades, as usual.

Subject: | Re: Wandering Wench is on her way |
Yep, that me! We "passed a good time".
It was great meeting and visiting with Arty (she hates "ma'm") and Randy. Also
got to meet another Drifter pilot from Beaumont, TX - Tom Harlagn (sp?).
Arty has taught me something new about XC flying. You don't have to worry about
those rough air mid-day landings if you don't take-off till afternoon. Seriously,
they left Nauga and False River late mostly because she needed to catch
up some much needed rest. She is a tough little thing and pretty amazing to
watch stuck out there on the front of the Drifter.
When you guys catch up with her at Sun-n-Fun, she is getting real close to getting
a Kolb. Those Drifter's eat a lot of runway both in and out.
Had a great visit, hope they did too. It was some great weather while they were
here. Rained 5" in 2 hours Sunday. Nauga Field had a water retention issue.

If you are going to Sun-n-Fun and want some of the hard to find Titanium screw
in tie-downs, check with Randy Simpson at Sun-n-Fun.
Randy is Arty Trost's flying buddy. He flies and "maintains" a Carrera. Neat
and interesting guy.
I bought a set (3ea with bag) from him. These things are nice and well made.
John H has had some for a while and this is the first time I found some.

Can you get blades from WD in odd lengths? I thought you could only get them in
evens....
Even with the mild problems with harmonics on my plane, my WD continues to shock
and amaze me with its performance. My 68" still gives me around 1000fpm at my
field elevation of 6300' and yet yeilds right at 100mph indicated at only about
5100 rpm slightly above half throttle.
I may have posted this already but I did also discover the other day that the harmonic
part of the vibration goes virtually away at cruise, so I may be able
to keep the WD on the plane as-is.
Dennis and I if all goes well with weather (and I get my leave from work) will
be travelling to MV a bit slower than that tho, as his Mark III is about a 70mph
airplane (reminiscent of my FSII). I'll have some kind of prop on the airplane
anyway whichever one works out to be the smoothest....

Randy sent me an email about a week before I blasted off to Alaska in 2004.
Asked me if I would like a set of his titanium tie downs. Replied with an
afirmative. A couple days before I took off my tie downs arrived. I am
very proud of them and take them with me every flight.
They are limited in rocky soil, like out West.
I also have some home made tie downs, rebar with a chain link welded just
below the top, to use in rocky areas. Can pound them in with a mallet,
rock, hachet, or whatever.
Also have some nice long 3/8" braided nylon rope. Nothing like landing in a
wind storm only to find the tie downs are spaced to far apart for your
ropes.

All ya gotta do is ask. They'll cut them any length you want, up to 72" (I
think that is their max length with nickle edges).
75% power is right at 5000 to 5100 rpm on a 912. A little more than 1/2
throttle. Throttle lever positions are not good indicators of power the
engine is producing. RPM works better.
I have a slight vibration at 5,000 rpm with these new blades pitched the way
they are now. I like the pitch, so I'll probably cruise at 5,100 or higher.
Every engine has a sweet spot where it is happiest/smoothest. That is where
I like to operate.
If, for some reason you find a vibration, use the throttle to find a better
place.
Even turbine engines have certain speeds that one should not operate because
of bad vibes. Doubt you will find an airplane engine of any type that is
absolutely vibrationless through the rpm range.
