I went to two fabric schools before I covered my
FireStar. Aircraft Spruce and Jim and Dondi Miller. Both said not to
rib stitch on round tubes. Both said not to rely on gluing fabric to the
ribs.
Jim Miller put on a good demonstration why you should not use glue only.
Polytac
has great strength in shear loading but very little in tension. Jim glued
two strips
of fabric together overlapping them then had two large men try to pull them
apart by
pulling on each end. This would be in shear. They could not pull the
strips
apart. Jim then took hold of one end of one of the strips and pulled up
putting the
glue joint in tension. The glue joint failed. As to rib stitching, both
schools said that
the round tube has only line contact with the fabric. The stitches will be
in an area
has no contact with the round rib. This will stress the fabric in that area
and could fail.
No gluing and no stitching means fabric rivets as per the Kolb instructions.

John H. & Gang,
Would like and appreciate some pictures if we can negotiate a cheaper
price. My arms and legs aren't worth much and it would take me twice as
long to finish my project without them.
I promise to use a different design, but I do like the red and yellow
combo. The gull wing doors should be a dead ringer that your crawling
into the wrong plane.
Do not archive
Later,
John Cooley
I have lots of pictures of my center section, but it will
cost you an arm and a leg to get them. :-) Besure and
paint your new MKIII a different color and design than mine.
I may have a hard time determining whose is whose if you
don't.

My first ultralight had a twist grip throttle on a stick that mounted to the
root tube overhead. It was very difficult to fly using that control setup.
The twisting of the stick grip was hard to separate from yaw control in your
head. After taxiing with it twice we changed it to a right hand mounted
throttle. I would suggest that you not persue that idea as putting to many
controls in one had becomes very difficult to separate the control
movements.

Topher/Gang:
Most of the Army's helicopters used twist grip throttles, when I was
flying, both piston and turbine. The Hughes TH-55 and the Bell OH-13
were two piston powered helicopters I flew with twist grip throttle
and no governors. The turbines had twist grip throttles and
governors. All, however, were installed on the collective control
stick, which was the "up and down" stick. Not on the control stick.
We learned to fly these helicopters very quickly. The throttle gave
me a problem because it was set up opposite the direction of
motorcycle throttles. I had a lot more motorcycle time than I did
helicopter time when I went to flight school. In fact, was riding a
little 125cc Benilli to school each day. I remember turning 90 deg on
the parking pad during pretakeoff procedures while skids were on the
concrete, using engine torque alone, no anti-torque pedal input.
During the sprag clutch check we were supposed to chop the throttle
from flight idle. Instead without thinking, I rapped it all the way
on . Good thing no one, like my IP, was standing beside the aircraft.
I prefer the conventional control set up in Kolbs, with the exception
of the center throttle in the MKIII. I have a lot of time flying the
conventional MKIII set up in the left seat with left arm across my
chest, but prefer to fly the right seat with throttle in the left
hand, right hand on the stick, between my legs. I know some of you
wise guys are going to say something about that last sentence. hehehe
Sorry to run on, but my fingers and memory got carried away.

Looking through my California Power Systems Catalog (CPS) of 2001 and
noticed this about the Warp Drive props:
Standard and High Aspect ratio blades. "Warp drive has a series of new high
aspect blade designs. Constant speed performance is achieved with fixed
pitch position blades (still ground adjustable) without using any type of
mechanism. The design itself provides the performance." It says to contact
CPS for more info on the "constant speed design".
The prices are about 20% higher than the standard aspect blade. The props
also have an option of the precision CNC center hub, a machined aluminum
center hub.
I know that there was a discussion recently about the P-tip Prince prop and
the Warp drive, but I don't think this high aspect prop was discussed.
Thanks,
Clay Stuart

ROFL. That was good Don, I loved it.
Actually, rib stitching around a 5/16" tube is like rib stitching any other
rib because the fabric is actually retained by the reinforcing tape which
overlays the Dacron covering, and regardless of all other considerations,
in order for the fabric covering to come loose, you first have to rip the
stitch or the rivet through the reinforcing tape. I no longer have it, but
years ago I had a Stits manual detailing the strength of the fabric,
reinforcing tape, and stitching, and all of them are pretty bulletproof.
(And now we could ask - is the reinforcing tape going to still be as
bulletproof with a 1/8" hole through it, or is it better off with rib
stitching cord over it? But we won't do that)
I used 1/4" Stits reinforcing tape, and it does pull down the fabric a bit
where the stitch secures it. This pull down would not have occurred with a
rivet. The pull down of the fabric is covered with the finishing tape and
is not readily apparent.
Just thinking about the posts that have occurred over the last couple days
concerning attaching coverings, I have decided that even though I am
persuaded that rib stitching has several advantages over rivets, I will not
bring it up again unless directly asked, we don't need too many tempests in
our teapots.
But I do hope you to keep up the good posts about engines, because I have
been using them in our EAA chapter newsletter, and everybody appreciates
them, thanks.

I wonder if using 3 inch fabric tape, polytac, and on the inside over the
tube equally on both sides would work in this situation verses stitching?

The helicopter setup always made perfect sense to me; raising the collective
required an increase in power and vice versa, so having those two controls
in the same hand made things easier not harder. When you have a directional
control in your hand and you add a power control that moves in a way that
would seam to swing your nose left and right was very confusing. Sure you
could get used to it and fly fine, but it was not intuitive. When the shit
hits the fan and a crosswind gust points your nose off the runway I am
willing to bet that 5 out of 10 people would twist that throttle trying to
turn the nose back to the runway, cutting the power instead and making a bad
situation worse. Intuitiveness of controls is very important under stress.

I think they are referring to the fast tape blade that a lot of us
have been using for some time now, and the HP or high performance hub.
The best person to contact and get the corrrect information is Daryl

Folks:
I have tried to correspond with Jim Gerken, by email, to correct the
original post he made comparing me and my mods to maintenance on BRS
systems. That was 24 hours ago. No response from him on my last
request. I guess I have my answer.
Here is a post to the Kolb List I wrote yesterday in response to his
original post on the subject above. I held it for a day to see if
things could get sorted out, with no sucess.
john h
********************************************************
Hi Jim G/Gang:
I like your subject line. :-)
However, I think you made a serious mistake trying to make me look
bad to the rest of the Kolb List, comparing ballistic recovery
inspections/repack schedules to what I have done to/with my Kolb
airplanes
over the years. Your information and the examples you use are totally
incorrect and misrepresented. Your purpose is very obvious to me,
whether it is to anyone else on this List or not.
| To me, chute maintenance schedule deviation seems a LOT like
structural
| modifications which deviate from Kolb's plans. We freely share our
ideas
| for modifying the Kolbs, but aren't we worried about the day one of
the
| wings modified by our recommendations comes apart?
I don't believe I have ever recommended to anyone deviation from
plans and building instructions for Kolb aircraft. I share what I
have done to my airplane and try to qualify why I do what I do. If
someone wants to do the same thing, they do it on their own and not
because I encouraged them to do it. I don't know about you, but I am
not worried in the least about wings modified by my recommendations,
because I do not recommend "do diddly squat".
The only modification that has failed, on one of my three Kolb
aircraft over the past 20 years, was a gear leg/axle socket. It
failed after many, many landings of all sorts and descriptions. It
failed because it was a part that had worn out. That proved it would
not last forever. Needed to be improved and updated. We did that.
Have been flying with the update for the last three years. Made that
last successful flight from Alabama to Barrow, Alaska, to Oroville,
WA, to Oshkosh, and back to Alabama, on gear leg/axle sockets designed
and built by Brother Jim. I might note, the way we have the gear
leg/axle socket made up now is the way Jim wanted to do them in 1991,
but I convinved him to do it my way. Had we gone Jim's way back then,
I may have made Barrow in 2000, and precluded a 10,000 mile recovery
trip in the old Dodge to bring Miss P'fer home.
| "Just a wild guess on my part" but, to me, Richard's observations of
the dependability of rockets was
| less likely to cause harm than encouraging others to drill holes in
| critical wing rib components and add weight in an unproven manner.
John's
| own good luck and hours of experience cannot alone be taken as proof
of the
| concept, as I understood Topher and then Dennis to add a couple days
ago.
"John's own good luck" is not what has kept me building and flying
Kolb aircraft for the past 20 years. My own foresight in the need for
a parachute recovery
system, prior experience with parachutes in the military and the fact
that I know they work and save lives, and the fact that I had one
strapped on my chest and to the airframe of the old Ultrastar in 1985
and again in 1990, is the reason I am still here. The failure of the
aileron bell crank on the Ultrastar was a design flaw that failed in
flight, not a Hauck Mod. Kolbs do not fly when aileron control is
lost. The wing failure in 1990 was my fault. I flew the Firestar
well outside the design envelope of the aircraft for 755 hours.
I think you misrepresented what Topher and Dennis were saying. I
think
you have intentionally misrepresented me.
| Another way of thinking about it is that John's experience may only
| indicate that Homer's wing was strong enough in its original design
to
| survive even the modifications.
How about explaining the above. I am too old and too dumb to
understand WTF you are trying to say. Thanks.
Jim G, you need to get your "wild guesses" straight. The Firestar
wings that failed me were strictly stock, built to plans and Kolb
instructions. No mods of any type by me or anyone else. It was not a
modification that caused the failure. Strictly pilot error.
I beefed up the MK III wing when I built them, based on the failure
mode of the Firestar wing and the anticipated environment the MKIII
would be flying during its life time. I have said time and again, if
Kolbs are built and flown as directed, within their design flight
envelope, they will probably last forever. My type flying does not
always adhere to normal, "around the patch a time or two" type flying.
My airplanes work much harder than the average Kolb. Therefore, the
mods that Brother Jim Hauck and I have come up with over the years.
Many of which are on the Kolbs that you and other Kolb people fly
today. Those mods started showing up on factory kits 13 years ago
this month. Whether you like it or not, Jim and John Hauck have been
a positive influence in the design and construction of your Kolb. The
mistakes I have made, the aircraft I have destroyed, the
repairs/upgrades we came up with, are all alive and well in your Kolb
airplanes. Many of you all are out there today trying to solve
problems we encountered and solved 20 years ago. I think they call
that, "Reinventing the wheel." Have at it. Have
the satisfaction of doing it your way. Will not bother me in the
least.
BTW: Do you know what the failure mode was on both wings of my
original Firestar? Did you have any idea how they were built before
you wrote this post? Do you know anything about the upgrade
Dennis Souder made to the outboard rib of the Firestar wing? Do you
know why he did that? He just explained to the List a couple days
ago. Did you know the failure mode and reason for the loss of my
Ultrastar? I just explained that one above.
The wing rib modification was designed and implemented by Old Kolb
Aircraft many years ago. Had to have been prior to 1991, when I built
my MKIII wings. It was recommended to increase the strength of the
outboard rib, which was getting damaged when folks would have hard
landings, failed gear legs and torn up the outboard end of the wings.
It worked. Even after drilling "all those holes" in them. It also
works on the first four outboard ribs and the noses of all main ribs
on my
MK III, with the exception of the inboard rib. The nose of the
inboard rib is 4130 chromoly steel, same as the rest of that rib.
The wings on my MKIII have somehow stayed together for nearly 2,000
hours and more than 12 years. Been to the Arctic/North Slope two and
a half times (almost got there in 2000). I can assure every one they
have been
thoroughly tested in flight environments that few others will ever
encounter in a MKIII. The left wing survived a serious accident with
limited damage, primarily because of the increased strength of the
ribs. I have proven to myself what I have done works. I have no need
to prove that to anyone else. And again, I DO NOT RECOMMEND AND
ENCOURAGE ANYONE TO DO ANYTHING!!!
| John, I am not trying to pick on you, but I am questioning the logic
of drawing a line at the parachute maintenance
| schedule mods, while encouraging structure mods. What about the
guys that
| do the structural mods but don't buy a parachute?
Jim, once again: I DO NOT ENCOURAGE FOLKS TO DO ANYTHING TO THEIR
AIRPLANES!!!
Guys that do any mods, do them on their own,......... period!!!
Whether a person does nor does not buy a parachute is none of my
business. I have always used a parachute and always will. I also
highly recommend others to use ballistic recovery systems that are
properly installed and maintained.
What I do with my airplane has absolutely nothing to do with the
parameters for inspection and repack of ballistic recovery systems.
There is a lot more critical criteria with parachutes and ballistic
recovery systems than meets the eye, especially someone ignorant of
parachute recovery systems.
I maintain my phylosophy that "hinting" to others that it is
reasonable to think a ballistic recovery system is ok to use because
"some guy in the Navy never saw a rocket failure of a rocket similar
to what is used in a ballistic recovery system" is stupid, foolish,
and could get someone "else" killed.
| I agree with John on this part: be careful guys. Careful flying,
careful
| reading, careful building/modifying. A lot of what you read here is
| opinion, not necessarily fact. Including this note.
You got that right.
What I write here is pretty much proven. If it is not, I always make
a notation that that is exactly what it is, on my part, opinion.
Take care and get your stuff straight before you jump me again.
If the Kolb List feels I am out of line in my response, so be it. I
got dumped on pretty hard and heavy by a few Listers last December,
without justification. When members left the List they blamed their
departure on me. I am slow and still trying to figure that one out.
I think it all started because I made some comment about not flying in
front of a Corvair engine as a joke, and some took it serious. If
that is the way the majority of the Kolb List feels, I would be more
than happy to leave the List. Easier for me to leave that a bunch of
other folks.
BTW: A few of those that made hasty departures from the Kolb List,
blaming me for their exits, have reappeared. Reckon they have
forgiven me for what ever I was supposed to have done, or they got
lonesome and missed us. My Mama used to tell me not to slam the door
on the way out. I might want to come back sometime. :-)
Ya'll take care,
john h
PS: There is one thing about having accomplished things
with these little airplanes that others have not. Once you have done
it, it
can not be taken away from you, no matter how hard others wish or try.

For the top longeron or fabric brace, wrapping around the tube is
enough to hole it. To keep fabric from drumming from the pusher prop,
some areas, like concave, need to be treated just like a wing rib,
with reinforcing tape, rib stitch, and finishing tape. Mine has held
up well over the last couple thousand hours of getting beat up.

Probably be the best bet. I just Polytac'd my fabric on and after a couple
hundred hours it started cracking the paint where the edge of the tube was.
Wasn't coming loose from the tube, but it had a stress crack in the
Polytone at the edge of the glue. Went back and put 3" tape on the outside
to cover the crack, and then instead of 3"tape on the inside, I used Goo
and glued it down. Bad mistake, when it dried, it shrank and caused a
dimple. Your idea would have been better.

Snuf/Gang:
I don't know about that. Never used that idea before.
Rib stitching works good and is really easy to do, if you do not have
to blind stitch. Blind stitching requires fabricating a curved needle
and a lot of stuff I learned and have since forgotten since I did mine
in 1991.
It might work, and again, it might pull loose in time. I do know that
the rear area of the fuselage fabric on Kolbs, especially higher hp
ones, get a hell of a beating continuously when that prop is making
power. The paint cracks first from constant bending created by the
drumming, then the fabric will eventually go. Plus it looks bad.
Sheet metal back there makes a lot more sense for durability.

We use 1/2 reinforcing tape when we use fabric rivets. Provides twice
as much area as 1/4" reinforcing tape. I don't think burning an 1/8"

strength reduction in 1/2" tape, but wouldn't want to do that with
1/4".

I've thought of doing that also. What would you do then? Rivet the sheet
metal ( I assume you'd use aluminum) to the cage tubes? Would the aluminum
also crack at the rivets because of drumming? Kirk

Snuf/Gang:
The end cap on my fuselage was originally fabric and aerodynamic,
rather than chopped off square the way the factory designed them.
That fabric lasted 100 hours and disentegrated. I replaced that with
some .020" alum about 1,800 hours ago. It is doing a good job and
does not drum enough to cause stress cracks and failure.
Sheet metal on the sides of the rear of the fuselage would have to be
attached with close spacing to keep it from vibrating and getting beat
up with prop drumming. If I was going to go that route, I would rivet
to welded tabs on the longerons and fabric braces.
Gentleman down in Panacea, FL, covered his fuselage with sheet metal.
Haven't heard how he is doing with it. He is in Duane Mitchell's AO.
Maybe Duane can give us an update on his progress.

John H/All
Good post. I would like to add a few comments to the
mix:
I spent about 7 months researching and learning
everything I could about kit planes before I Chose a
Kolb, and since, I have continued to learn everything
I can. I have some varied flight and
mechanical/engineering experience and so I had a very
specific mission in mind for my plane. To this end I
have been asking this list for specific information on
every imaginable sort of modification and change, then
sitting down with my local advisors (a motley crew of
A&P's, aviation engineers and other builders) and
sorting through what makes sense for my mission. This
project is an opportunity to build something for me,
my way, and my way is to look at every aspect of the
plane and see what I might change to suit me. This
can be tiresome and boring for others; my friends
sometimes ask if I am building a space shuttle, or a
plane ;-)
But it suits me.
I think TNK, Kolb aircraft and our community of
builders are the most impressive lot I have come
across and am proud to be a part of it. I also think
the airframe is remarkably well designed and perfectly
matched to it's intended use, and through the efforts
of us builders and TNK, has improved over time. By
sharing our ideas on the list, we subject them to peer
review, and that is the best way to improve a mature
product. For peer review to work, we must each
consider a new idea carefully before knee-jerk
criticizing it because "I didn't do it that way", or
"I've never heard of that". I try to consider what
effect some change could make, often asking people
with experience in that area. I also try to never
guess blindly; it just upsets people that know more
than I do about something. Professionally, I am paid
to find problems and devise solutions; I'm having fun
doing it for myself, instead of for my employer. Just
because I question everything, isn't to be inferred as
some kind of insult toward Kolbs or anyone's building
style.
John H. and many, many others have suffered my
questions cheerfully and helpfully. NO ONE has ever
"told me" how I should build my plane, quite the
opposite: I ask "I want to do that, how did you do
it?" and the answer usually starts something like "for
my situation I did...." or "not sure if this is the
best way, but I....".
So my message to John H., and many others is: please
keep answering the questions asked in spite of a
minority who chose to view it as an insult when we
propose to experiment with our experimental airplanes.

Clay,
I would use a hand riveter. Rivnuts are easy to over-squeeze if they are the aluminum
ones, then you gotta drill em out and start over. Don't ask me how I know
that. On the steel ones it also real easy to strip the threads when you're
squeezin em and they're even more of a pain to get out. (Specially when the keyway
strips as you're drillin em and it just spins in the hole.) Again, don't
ask. hehehe Good luck.

Don,
Yes, I mounted a motorcycle throttle on the joy stick. I've not
encountered any of Topher's concerns of unwanted secondary input into
the control system. I've done extensive competition flying with that
setup & encountered numerous emergency situations over the 15+ years of
use & never had a thought of going back conventional. On my setup, I
installed an adjustable tension device that allows the throttle to
retract with the force of the throttle return spring, or at the other
extreme, it locks the throttle tight. I adjust it to hold the throttle
snugly in what ever position it is in if I were to take my hand off the
stick. So, in effect, I can control the stick with one finger if I
choose, & the throttle setting remains the same. Perhaps this is why I
experience no secondary input. AS I said before, I like it so much that
I converted every plane I've had since. When used in conjuction with
flaperons it allows me to vary the lift of the wings, the power of the
engine, and the three axis of direction, all simultaneously. Some might
consider this suicidal & accuse me of leading this list astray, so for
those of you who are not thinking adults, please realize, this is not
God speaking. [[And as I said on my previous reply (which by the way,
hasn't appeared on the List after 2 attempts-- Conspiracy?--) to some
misconstrued "advice" I supposedly gave on parachutes, "If anyone does
believe I am God, send me your bank account info & I'll properly reward
you."]] Anyway, back to the topic, I do not experience all that control
as overload. It gives me more control in the moment when I most need it.

Subject: RE: Kolb-List: BRS Canister Repack
This is my 3rd attempt to post this response. For some reason, I
haven't seen the 1st 2 attempts? Other posts went no problem.
Hey John,
If you read my post below more closely you'll notice that I
didn't give advice. I did repeat 1st hand info & give my opinion. A lot
of wise responses were given to this post, most of which I agree with.
However, economics is a factor to be included in any decision of safety.
At what price are we willing to pay or shall we say can we afford to
stack the deck in our favor. There is no absolute guarantee of safety,
therefore some degree of sanity must be applied at some point. One's
degree of safety is therefore related to one's financial resources, not
to mention one's fear of death, and of course, one's comfort zone of
risk taking. Some would think it unreasonable to fly at all. In the
end, our safety is both arbitrary and based on a logical assessment of
risk. My opinion is that if a chute can be professionally repacked &
the rocket is five years past its recommended shelf life, I would feel
responsible in using it. I believe it is a defendable opinion,
certainly it is not an infallible truth, but I assume all on this list
realize I am not God! (If somebody out there does, send me your bank
account numbers & I will make sure you are properly rewarded.)
opinion as well. Hopefully all on this list are responsibly sifting
thru all information offered here, especially mine.

That sounds great.
How long can I extend the repack on my BRS?

PS: Of course, you are volunteering to be the test dummy for these
extended
inspection and repack times???
PSS: We need to be very careful giving advice to folks based on
speculation
that might mean the difference of life or death. There are a lot of
very
serious aspects to our sport of building and flying Kolb aircraft.
Let's
have fun, but be careful. None of us are immune to gravity, or exempt
from
"Murphy". If I was going to give someone advice on whether they should
extend the inspection and repack cycle of their BRS Balistic Recovery
System, it would be to follow the directives. If there are any
questions,
direct them to the professionals at BRS.
PSSS: What does the Navy use the BRS rocket for?

Guys,
Ians' recent post mentioning 912S powered Slingshots got me thinking that I have
not seen any posts from the Woods brothers from Georgia in a long time.
Bill I beleive and I forget his brothers name. They had their beutiful prize winning
Mk-3 and Slingshot, both powered with 912s, at the 2000 TNK fly-in.
The level of finish on those two aircraft was breathtaking and they were extreamely
generous with their time explaining some of the ideas they incorporated into
their birds.
Has anyone kept in touch with them? And if so, how are they doing?
I would like to thank them belatedly for the advice they offered me at TNK and
wish that they were active here on the list, they have a lot of technical knowhow
that would be a benefit to all Kolbers.
Later,
Denny Rowe, MK-3, PA

I know that at the least they sold the Slingshot, if I remember correctly,
Bill purchased, or was going to purchase, a certified aerobatic aircraft
like a Citabria/Decathlon. The Woods brothers were indeed generous with
their time, I could not have finished my Slingshot without their help.
If anyone would like the email address for Bill Woods please email me BC.

Hi Alan/All:
Sounds like resonance.
Aircraft, fixed and rotary wing, sometimes have certain rpm ranges
that create resonance. Best not operate in those rpm areas. If it
was me, I would fly a little above or a little below out of the range
it occurs.
The Hughes TH-55 primary trainer could get in ground resonance if the
engine was held in a yellow arc area too long. Result was complete
destruction of the aircraft. It would get into ground resonance with
skids on the ground.
Here is a good example of what one type of resonance can do to a
helicopter:
http://www.fwcvhpa.org/fw/ground.htm
Ground resonance is probably not a good example/comparison of the type
resonance/vibration you may be experiencing. I'll just hang loose and
let the experts explain what may be happening and how to prevent it.
Take care,
john h

Hello Ed et al,
I did the weight and balance on my FireFly in the the full flight configuration.
That's with the fuel tank full, me in the cockpit, helmet, radio etc. I did
it just to be certain that if my little 447 ever quits during climbout (10 to
15 mph above stall) I will not have trouble getting her nose down and gliding
without a tail-heavy-induced stall. You can probably get it done while it's still
raining outside so you won't be loosing any air time.
Make sure your prop is set to a pitch low enough to allow the engine to reach the
required top RPMs specified in the break-in procedure. I do not have access
to my log book right now or I would tell you what pitch I used. Mine ran a little
on the hot side while she was seating those new rings. Watch your temperatures
especially during descents.

List,
I think I almost have my plane finnished. I really wish I had someone In the
Houston area to scrutinize my building, that has built a Kolb themselves. Any
takers?
Are there any Firefly builder/owners that built per plans that had to
alter anything or add weight anywhere to get there Firefly to fall into the
correct limits. Seems I heard someone say a w/b is not necessary if I followed
the
plans exactly. I did. Should I worry about it? I still need to break in the
engine. Any thing I need to watch out for other than making sure I have the
tail secure..

Hi Kolb drivers
I agree with Topher ..I flew a Rotec Rally with the control stick
hanging from above.
This was confusing enough..The stick had a twist grip throttle on the
end which I didn't
like because I had to hold it all the time,wereas a conventional
throttle you can
set and forget.

Hey Guys,
Has anyone had any experience with the clutch system for the 582 C
gearbox? I'm looking for a way to reduce or eliminate most of the
vibration at idle without having to raise the idle speed too high.
Anyone had a clutch slip or fail? The only drawback that I see is if
your starter would fail you would not have the ability to prop. start as
a backup. Which brings to mind another question. Has anyone had a clutch
installed on an engine without electric start? I know that it is very
hard to pull the engine over without the prop installed, and assume it
would be the same with the clutch system. -- Earl

Wasn't the Ralley a piece of S***! I occasionally had nightmares about
those clothesline control lines breaking in flight! It did fly all right as
long as you didn't have a cross wind. The spoiler roll control was fairly
pathetic.

Hi All:
Anyone familiar with the engine oil thermostats for VW's or other

One of the goodies I discovered at the recent 912 School was approval
of installing and running an oil thermostat. I found two on the
internet. They are not that expensive. Looking for any info before I
hit the send button to order one.

Duane,
Good to hear from You. When you get the time It would be most helpful
if you could give me the weights you obtained at each wheel So I can compare
them with mine. That formula Kolb has in their manual is hard for me to follow
& I dont trust myself with it. Also see if you can find what pitches you set
your prop at during break in. I have the 447 & 2 blade Ivo just like yours .
This info might benefit others on the list. I never did hear If You finnished
& flew that Mark 111 or did I just miss the post?
