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 points
and potential rubbing, chafing, scratching and abrasion between parts. I spent
a lot of time putting pieces of split rubber tubing over the steel frame tubes
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 while
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 it needed
to make bends or flex a little. Lots of "EAA homebuilder standoff" assemblies
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 the
tubes should be 22-24 inches before they join together. That distance, while
not "critical" by any means, gives you the best "tuning" of the exhaust pulses
helping pull the exhaust gas out of the cylinders. I used this as a starting
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 buckle
assemblies to tie the fuel jugs down to the fuselage tube. I had glued a rubber
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 vibrations.
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 strap
was directly rubbing on the bottom of the fuselage tube, and eventually might
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 rubber
tubing on the bottom, putting a layer of foam between the webbing and the bottom
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 webbing.

THEN, after more insane asylum paranoia, I realized that the plastic buckles that
I put on the webbing wereplenty strong enough for any negative G loads on the
fuel jugs... but the buckles were too easy to un-lock if someone brushed against
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 accidentally
(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 world.
So I take a LOT longer to be convinced somehting is safe.

 Pike" 

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

The Duc brand of propeller from Europe is supposedly one of the more efficient,
delivering the most thrust. Definitely not the least expensive route however.

Subject: Re: Kolb-List: best props


Props are one of those things that require a lot of thought. Ive run two blade
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 results,
very adjustable. They held up well in sandy and decomposed granite runway conditions.
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. They
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 opinion.

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 for
the b-box by Rotax. 
The IVO was just slightly over, and the WARP DRIVE was way over the recommended
limit. (It is a very tuff prop though) 
The POWERFIN is stiffer than the IVO even though the IVO has a little easier pitch
adjustment than the Powerfin. I had a IVO on my paraplane. I prefer the Powerfin
over the IVO. Just my opinion, they are all good props.
