Kolbers,
I have a new KievProp sitting in a box, and hope to be utilizing it soon. Never
heard anything bad about them, when I was doing my research, a while back.

Years ago the owner of Great Plains Aircraft (VW engine sales/builder) put
PowerFin, IVO, and Warp Drive props on one of his engines. I think it was
one of the reduction drive engines. PowerFin gave him the most static
thrust and the lightest weight. I have been flying with a PowerFin for
better than 15 years and have had good luck with it. Warp Drive has a
reputation of being very strong being solid carbon fiber but is heavy which
can cause problems with the weaker Rotax gear boxes. I had a 2" X 5/8" bolt
go through my PowerFin in flight on a trip. There was damage but the prop
got me the remaining 400 miles home.

Hi Rick N/Kolbers:
Can you cite me some examples of Warp Drive props causing gear box
problems/failures on B or C gear boxes? I personally have not heard of
any. Guess I could call Daryl at Warp Drive and get his input.
I put a couple hundred hours on a C gear box, Warp Drive 3 blade, and
582 on my MKIII. Did OK. No problems.
Put about 50 hours on a 3 blade GSC wooden prop with inlaid urethane
leading edges. For some reason, which I could never determine, the GSC
failed, collecting all three blades on the tail boom. That one cost a
lot of work replacing the tail boom which was knocked about 5 degrees
out of column. Also slung the starter out of the bell housing. The
mounting bolts were still in the engine case. In addition, slung the
carbs out of their sockets.
I have attached a couple photos of a GSC and a Warp Drive blade grip.
Not a whole lot keeping the GSC from slinging a blade. Look closely and
you can see the individual carbon fibers which loop around a steel ring.
We dissected these two grips to see how they were made. The Warp Drive
was on a friend's RANs S-12 which got away from him when he cranked it
while standing outside the aircraft. Had been working on carbs and
forgot the throttle was wide open. There were no wings on the aircraft
powered by a 912. The RANs went about a quarter mile when it hit a berm
and launched skyward through a patch of planted pine trees, truck
diameter about a foot. The Warp Drive blade cut halfway through the
trunk before it broke. I have never seen how any of the other brands of
popular props are constructed.
I have flown Kolb Factory aircraft with IVO props on two and four stroke
engines. They performed ok in the traffic pattern, but don't know how
they would do on a long cross country. I do know that they are not very
durable.
Kolb aircraft, being pushers, are eventually going to have something
fall off the engine or airframe. When it does, it is likely going
through the prop.

On the issue of prop mass vs gearbox: I'm pretty sure I've seen specs in
Rotax documents that specify max prop mass moment of inertia for each of
their boxes. Shouldn't be too difficult to find the number for a particular
gearbox, and compare to the prop's MMI. In case anyone's wondering, yes,
it's real thing, and serious stuff. I have no idea about any particular
combination, but if you're contemplating a new combination, it's certainly
worth checking, especially if the new prop is significantly heavier than
typically used props for that particular gearbox model.

Found this regarding the subject on Rotax recommendations on MMI
I ran Ivoprops for many years without any prop issues. We did have problems w
ith wave washers failing in the early B gearboxes.
Low MOMENT-OF-INERTIA in a propeller means faster spool-DOWN time, letting a
CLUTCHed prop stop sooner! Rotax has set a limit for how much inertial mass
is allowable on the B, C & E Gearboxes. On the A/B-box they want propellers
with no more than 3,000 kg/cm2. A 72" =93 3-blade Ivoprop Ultralight p
ropeller is about 4,500 kg/cm2. The same Warp Drive is over 10,000 kg/cm2. P
OWERFIN Propellers are 2,500 kg/cm2 for a big three-blade model and 1,800 kg
/cm2 for a two- blade model. POWERFIN is the only U.S. manufacturer to have a
ddressed this issue and met the challenge of designing a very durable, low i
nertia propeller for the Rotax gearboxes!

John
No examples. Just discussions from the Kolb group about the mass of a prop
that some of the rotax gear boxes can handle. No doubt Warp Drive makes a
great prop. Props are a bit like religion, easy to offend someone that owns
one.

Just as a point of interest I checked on the Hirth G50/GK50 gearboxes. Rated
for 20 to 110 hp engines.

Subject: Re: Kolb-List: Re: My Firestar Project Update
Richard thank you for your observation and compliments. My work is nowhere
near
the quality and finish of champion trophy airplane builders. 90% of what I
am
doing is not for "show quality", but simply to remove as many failure poin
ts
and potential rubbing, chafing, scratching and abrasion between parts. I sp
ent
a lot of time putting pieces of split rubber tubing over the steel frame tu
bes
where I want to attach something with a Ty-Rap (zip-tie), so nothing would
start eating into the steel tubes. Hours were spent on this kind of stuff w
hile
I was building the fuel system. I used HDPE plastic tube everywhere I could
run the lines fairly straight, and used the blue urethane tube only where i
t needed
to make bends or flex a little. Lots of "EAA homebuilder standoff" assembli
es
in the engine area. These are short lengths of tube with a zip-tie through
the tube and around something on either end,which basically prevents lines,
wires, tubes, etc. from "whipping" and waearing out prematurely. No rocket
science
whatsoever, but it makes everything last longer.
The direct answer to your suggestion about joining the exhaust pipes behind
the
main keel tube is that the HKS engine importer told me that the length of t
he
tubes should be 22-24 inches before they join together. That distance, whil
e
not "critical" by any means, gives you the best "tuning" of the exhaust pul
ses
helping pull the exhaust gas out of the cylinders. I used this as a startin
g
point, knowing full well that to get the last percentage pof power form the
engineyou'd
have to do a bunhc of testing and dyno work like race engine builders
do. I have no need for that, but I figured if the engine mfg. can give me a
basic deimension then I can at least roll the dice on that.
BTW today I finished most of the fuel system. I madeup webbing strap and bu
ckle
assemblies to tie the fuel jugs down to the fuselage tube. I had glued a ru
bber
strip on the top of the fuselage tube in the fuel tank bay, so the furl jug
and aluminum tube would not start working on each other due to normal vibra
tions.
Then, after scratching my head for a while and thinking about what could
possibly wear, chafe, rub, or grind... I realized that the nylon webbin str
ap
was directly rubbing on the bottom of the fuselage tube, and eventually mig
ht
wear through something. So I took it apart and ran the webbing through two
short
pieces of foam rubber tubing, and reinstalled everything with the foam rubb
er
tubing on the bottom, putting a layer of foam between the webbing and the b
ottom
of the fuselage tube. So now the webbing can't rub through the paing on
the fuselage tube, and the fuselage tube can't wear away any of the nylon w
ebbing.
THEN, after more insane asylum paranoia, I realized that the plastic buckle
s that
I put on the webbing wereplenty strong enough for any negative G loads on t
he
fuel jugs... but the buckles were too easy to un-lock if someone brushed ag
ainst
them at the wrong angle. So after more head scratching, I figured out a
way to use small zip ties as locking devices, preventing anyone from accide
ntally
(or intentionally) squeezing the buckles to un-lock the fuel tank retaining
straps.
I know that this is paranoid "certified airplane overkill" thinking, but I
come
from the certified airplane world as much as I come from the experimental w
orld.
So I take a LOT longer to be convinced somehting is safe.

I hate to sound critical because I
always have to redo all my stuff 3 times before I can get it
to work right, so that says a lot for my eyeball
engineering... (Starting the redo on the gap seal for the
forth time tomorrow) And meanwhile all your work in those
pictures is way ahead of anything I can do in terms of
quality control. So I feel like a shade tree mechanic
telling a pro how to do his stuff.
But - just looking at your pictures, if
it was me, I would have your two exhaust pipes come together
right behind the rear main fuselage tube, because that is
almost exactly aligned with the center of pivot of the
engine on its motor mounts. Yours extend down way beyond
that. If it were me, I would terminate them there with a Y
into a ball joint.
By doing that, all the radial movement
of the engine would sort of focus at that point. So if you
had your ball joint there, with just one pipe going down to
the rest of the exhaust assembly, now you have isolated the
engine movement from the main mass of the exhaust system,
and taken a lot of stress off the upper exhaust pipes. And
possibly eliminated some vibration, because you have also
removed some exhaust system mass from the engine and it's
associated movements, and what movement there is, is now
minimized by having it aligned with the center axis of the
motor mounts, at which point you have a movable ball joint.
Worth what ya paid for it...

John Gilpin is a man after my own heart. He has had more flying
adventures than you can shake a stick at. He has a knack for getting
into trouble and getting out just as easy.
A few years back John G spent a couple weeks with the gang at the Rock
House. He held my attention the whole time I was there. He has a lot
of stories to share about his flying adventures. One of the best is
when you clipped a power line and crashed somewhere Outback.
Few will fully understand the experience of flying solo, completely self
supported, in truly remote areas. John G has been there and done that
many times.
In addition, John G has made several trips to the US to travel and
explore extensively in our country in a Kolb. He finds it difficult to
sit still very long.
Thanks for sharing, John G.

Two-cycle engines have their exhaust "tuned" to have a low-pressure wave
at the exhaust port when the piston moves below the port. This helps pull
fuel-air mixture into the cylinder while pulling the burnt gases out. I
think it is determined by the length and size of the exhaust pipe so be
careful you don't lose a lot of horsepower.

Subject: Re: Kolb-List: best props
Props are one of those things that require a lot of thought. Ive run two bl
ade
wooden props. (Tennessee propeller) very good at matching prop to specific
engines.
Real good composite leading edges are available. Reasonably priced.
Ive run Ivoprops in both two and three blade configurations with good resul
ts,
very adjustable. They held up well in sandy and decomposed granite runway c
onditions.
The only downside was that theyre heavy and seem to take a little longer
to wind up. The blades do flex a lot and on some Kolb models require a prop
extension. Added cost.
At the present time Im liking Powerfin propellers. Beautifully CNC machined
hubs
and light very stiff composite blades. Ceramic leading edges are available.
Im sure theyd be great in really abrasive conditions. Extra cost though. Th
ey
come in two and three blade versions. They are expensive, but worth the it
I think.
Warp Drives are really good looking props. They look really well made. Ive
heard
that they are great propellers. Ive been told that theyre on the heavy side
too. But, thats hearsay. I have no experience with them, so I have no opini
on.
I think the two blade props are more efficient for around performance. But,
I like
three blades simply because I like the climb power and smoothness. I think
that I will loose a little on cruise with a three blade. But, Im all about
takeoff
and clearing trees up here. Just my input. Its worth what it cost you. Just
opinions. Have a great day! George

Warp Drive blades are solid carbon fiber. Each fiber runs from tip to grip
and back to tip. They are tough, efficient, reliable, and perform. Wish
you could see all the places my Warp Drive Props have pushed me. Would not
have attempted many of those flights with anything but Warp Drive.
Most of the other composite props are fiberglass/plastic over a foam core.
They won't stand up to the punishment a Warp Drive will.

I also have a 3 bladed Powerfin F-blade with same engine set up as your own
. Has
been a reliable and smooth prop for me, it meets the recommend mass limit f
or
the b-box by Rotax.
The IVO was just slightly over, and the WARP DRIVE was way over the recomme
nded
limit. (It is a very tuff prop though)
The POWERFIN is stiffer than the IVO even though the IVO has a little easie
r pitch
adjustment than the Powerfin. I had a IVO on my paraplane. I prefer the Pow
erfin
over the IVO. Just my opinion, they are all good props.

Subject: Re: Kolb-List: Re: My Firestar Project Update
Richard thank you for your observation and compliments. My work is nowhere
near
the quality and finish of champion trophy airplane builders. 90% of what I
am
doing is not for "show quality", but simply to remove as many failure poin
ts
and potential rubbing, chafing, scratching and abrasion between parts. I sp
ent
a lot of time putting pieces of split rubber tubing over the steel frame tu
bes
where I want to attach something with a Ty-Rap (zip-tie), so nothing would
start eating into the steel tubes. Hours were spent on this kind of stuff w
hile
I was building the fuel system. I used HDPE plastic tube everywhere I could
run the lines fairly straight, and used the blue urethane tube only where i
t needed
to make bends or flex a little. Lots of "EAA homebuilder standoff" assembli
es
in the engine area. These are short lengths of tube with a zip-tie through
the tube and around something on either end,which basically prevents lines,
wires, tubes, etc. from "whipping" and waearing out prematurely. No rocket
science
whatsoever, but it makes everything last longer.
The direct answer to your suggestion about joining the exhaust pipes behind
the
main keel tube is that the HKS engine importer told me that the length of t
he
tubes should be 22-24 inches before they join together. That distance, whil
e
not "critical" by any means, gives you the best "tuning" of the exhaust pul
ses
helping pull the exhaust gas out of the cylinders. I used this as a startin
g
point, knowing full well that to get the last percentage pof power form the
engineyou'd
have to do a bunhc of testing and dyno work like race engine builders
do. I have no need for that, but I figured if the engine mfg. can give me a
basic deimension then I can at least roll the dice on that.
BTW today I finished most of the fuel system. I madeup webbing strap and bu
ckle
assemblies to tie the fuel jugs down to the fuselage tube. I had glued a ru
bber
strip on the top of the fuselage tube in the fuel tank bay, so the furl jug
and aluminum tube would not start working on each other due to normal vibra
tions.
Then, after scratching my head for a while and thinking about what could
possibly wear, chafe, rub, or grind... I realized that the nylon webbin str
ap
was directly rubbing on the bottom of the fuselage tube, and eventually mig
ht
wear through something. So I took it apart and ran the webbing through two
short
pieces of foam rubber tubing, and reinstalled everything with the foam rubb
er
tubing on the bottom, putting a layer of foam between the webbing and the b
ottom
of the fuselage tube. So now the webbing can't rub through the paing on
the fuselage tube, and the fuselage tube can't wear away any of the nylon w
ebbing.
THEN, after more insane asylum paranoia, I realized that the plastic buckle
s that
I put on the webbing wereplenty strong enough for any negative G loads on t
he
fuel jugs... but the buckles were too easy to un-lock if someone brushed ag
ainst
them at the wrong angle. So after more head scratching, I figured out a
way to use small zip ties as locking devices, preventing anyone from accide
ntally
(or intentionally) squeezing the buckles to un-lock the fuel tank retaining
straps.
I know that this is paranoid "certified airplane overkill" thinking, but I
come
from the certified airplane world as much as I come from the experimental w
orld.
So I take a LOT longer to be convinced somehting is safe.

I hate to sound critical because I
always have to redo all my stuff 3 times before I can get it
to work right, so that says a lot for my eyeball
engineering... (Starting the redo on the gap seal for the
forth time tomorrow) And meanwhile all your work in those
pictures is way ahead of anything I can do in terms of
quality control. So I feel like a shade tree mechanic
telling a pro how to do his stuff.
But - just looking at your pictures, if
it was me, I would have your two exhaust pipes come together
right behind the rear main fuselage tube, because that is
almost exactly aligned with the center of pivot of the
engine on its motor mounts. Yours extend down way beyond
that. If it were me, I would terminate them there with a Y
into a ball joint.
By doing that, all the radial movement
of the engine would sort of focus at that point. So if you
had your ball joint there, with just one pipe going down to
the rest of the exhaust assembly, now you have isolated the
engine movement from the main mass of the exhaust system,
and taken a lot of stress off the upper exhaust pipes. And
possibly eliminated some vibration, because you have also
removed some exhaust system mass from the engine and it's
associated movements, and what movement there is, is now
minimized by having it aligned with the center axis of the
motor mounts, at which point you have a movable ball joint.
Worth what ya paid for it...

John Gilpin is a man after my own heart. He has had more flying
adventures than you can shake a stick at. He has a knack for getting
into trouble and getting out just as easy.
A few years back John G spent a couple weeks with the gang at the Rock
House. He held my attention the whole time I was there. He has a lot
of stories to share about his flying adventures. One of the best is
when you clipped a power line and crashed somewhere Outback.
Few will fully understand the experience of flying solo, completely self
supported, in truly remote areas. John G has been there and done that
many times.
In addition, John G has made several trips to the US to travel and
explore extensively in our country in a Kolb. He finds it difficult to
sit still very long.
Thanks for sharing, John G.

Two-cycle engines have their exhaust "tuned" to have a low-pressure wave
at the exhaust port when the piston moves below the port. This helps pull
fuel-air mixture into the cylinder while pulling the burnt gases out. I
think it is determined by the length and size of the exhaust pipe so be
careful you don't lose a lot of horsepower.

stop by for a visit. I don't have a fabulous private airport or a big rock

and our "wilderness" here in LA is a different kind of adventure to say the

Subject: Re: Kolb-List: best props
Props are one of those things that require a lot of thought. Ive run two bl
ade
wooden props. (Tennessee propeller) very good at matching prop to specific
engines.
Real good composite leading edges are available. Reasonably priced.
Ive run Ivoprops in both two and three blade configurations with good resul
ts,
very adjustable. They held up well in sandy and decomposed granite runway c
onditions.
The only downside was that theyre heavy and seem to take a little longer
to wind up. The blades do flex a lot and on some Kolb models require a prop
extension. Added cost.
At the present time Im liking Powerfin propellers. Beautifully CNC machined
hubs
and light very stiff composite blades. Ceramic leading edges are available.
Im sure theyd be great in really abrasive conditions. Extra cost though. Th
ey
come in two and three blade versions. They are expensive, but worth the it
I think.
Warp Drives are really good looking props. They look really well made. Ive
heard
that they are great propellers. Ive been told that theyre on the heavy side
too. But, thats hearsay. I have no experience with them, so I have no opini
on.
I think the two blade props are more efficient for around performance. But,
I like
three blades simply because I like the climb power and smoothness. I think
that I will loose a little on cruise with a three blade. But, Im all about
takeoff
and clearing trees up here. Just my input. Its worth what it cost you. Just
opinions. Have a great day! George

After looking at the prop, I found a few nicks and bruises on it and would
like to replace it. What is the best prop for the 503? I have researched t
he
achives and am still confused.

Warp Drive blades are solid carbon fiber. Each fiber runs from tip to grip
and back to tip. They are tough, efficient, reliable, and perform. Wish
you could see all the places my Warp Drive Props have pushed me. Would not
have attempted many of those flights with anything but Warp Drive.
Most of the other composite props are fiberglass/plastic over a foam core.
They won't stand up to the punishment a Warp Drive will.

I also have a 3 bladed Powerfin F-blade with same engine set up as your own
. Has
been a reliable and smooth prop for me, it meets the recommend mass limit f
or
the b-box by Rotax.
The IVO was just slightly over, and the WARP DRIVE was way over the recomme
nded
limit. (It is a very tuff prop though)
The POWERFIN is stiffer than the IVO even though the IVO has a little easie
r pitch
adjustment than the Powerfin. I had a IVO on my paraplane. I prefer the Pow
erfin
over the IVO. Just my opinion, they are all good props.

...*He has a knack of getting into trouble and then getting out just as eas*
y....
It's true that I did once did mention to my flying instructor that, "... I
was good at getting out of trouble...", and he didn't reckon that was a
real good answer for flying strategy..... That off-hand comment was based
on long experience of rough travel in foreign countries and long motorcycle
trips in such countries, but it really should have been stated as, "...
good at dodging trouble ...". Willing to go into tight situations but very
much alert to the risks and always assessing 'get out' options in time.
That applies particularly for my ultralight flying. Often it's not very
relaxing because my mind is spinning all the while, assessing the risks and
outlanding options.... I'm not very interested in flying just to get up
into the air around the same home patch, and not at all interested in low
flying just for the thrills..... My aircraft is a means of transport to get
out and see and explore new vistas from above.
Sometimes that means getting out over rough country but always carefully
assessed as being survivable. And of course preparation beforehand.
Hundreds of practiced dead stick landings, so that I know what the feel of
no engine noise is like, and what the glide slope will be, and exactly
where I'll set down at minimum speed. (Actually I really enjoy that silent
glide with just the sound of the wind, and assessing speed and momentum
without watching the instruments....) I've never found navigation
difficult, and GPS makes it so sure and easy these days. In case of
stranding I always carry an ELT and Spot locator, and carry enough survival
needs until help could come. I follow roads or near them wherever possible.
Considering all those factors in planning and flying is what makes the
challenge interesting.
Remote Australia isn't nearly as threatening as it appears, if you're
always aware of the options and are prepared just in case. I never felt
very brave or reckless on those trips. Just a whole lot of fun!
Same for when I was flying Kolbs to have those fabulous adventures in the
USA.
Different strokes for different folks, but try it you might like.....

I've posted on this before, but haven't noticed any action.....
John Hauck needs to write up some of his extensive flying adventures. And
he certainly does have plenty of great flying adventures to tell. We've
only heard bits and pieces but it does need to be put together and
published.
It's not all that hard these days. There are several formats and programs,
but the easiest I've found is the Google Blogger that I used. It's set up
as a blog so that the latest post ends up at the front and the beginning at
the end, not like a good story. So what I've come up with is to do the
whole story in one post. Just start with a post and then keep adding to the
story and updating that same post. I've put as many as 200 photos and long
story in the one post, built over time, and it seems to work OK. I'm no
expert in such work, but I find it really easy to write and edit and add
photos in Blogger. And the price is right, free....
Come on John, do it while you can.
You've got so much to tell.
And we know you have the ability to tell a good story....
Maybe if everyone pushed on him...........
