I haven't been following this thread so I don't know what carb you're

for altitude.  This would include many motorcycle carbs and the SU carb
found on some English automobiles.  It would not include the Posa.

Subject: KR: Re: Canopy

I *really* want to make my own canopy.  Well, I'll even go so far to say
that I *will* make my own canopy :)

Here's my "foolproof" plan (BWG).....

1.  Make a jig and then stretch rubber over it and pressurize it to see what
kind of shape I get to make sure I can get proper head clearance. (we use to
do this for mechanical engineering design- it simulates 3-D stress on an
irregular shaped flat plate very well.)

2.    Use thin acrylic with the same mold and put it in wife's oven and
pressurize it as per #1 (don't tell my wife.)  Maybe I'll sell this one to
some quarter scale model builder :)

3.  Go for it with the real thing.  It will no doubt take a few tries but
for $600 (canopy plus shipping) I can afford to play with it!

I'm planning on using a techniqe like this...

<<<<I read an article about "blown" canopies but have not tired the
technique.

Writer said take a sheet of material and place it on a flat, rigid
board 3/4" or 1" thick with a "hole" drilled in the center for the
air pressure (LOW pressure I'm sure). Install an "shape" ring of the
same rigid material on top and screw/bolt it down all around the
"flange edge" about every 6" or less. The plastic should be "sealed"
between the lower full board and the "under side" of the plastic so
as air is allowed into the canopy to form it, the pressure is
maintained evenly.

Insert the from and plastic into an "oven"; author built a plywood
box with vents cut into the upper surface, and heat SLOWLY until the
plastic begins to soften. Inject Low pressure air through a hose with
a valve to "trap" pressure when desired shape is attained. remove
heat (The author used a propane power space heater with a blower like
a construction job unit used in winter) and allow to cool slowly
while ensuring pressure remains constant; i.e. the seal around the
lower surface is CRITICAL as is the fastening of the form ring every
6" or less (I plan to use screws spaced about every 3 or 4 inches
max). Remove from form, cut to correct dimensions nad install. The
author suggested making a couple at one time to have a spare if you
mess up the first install job or break one in use. He also indicated
as he made many more than really, he "sold" acouple to other builders
to recoup the cost of materials and supplies, i.e. his canopies
actually cost him labor.

hope this helps, Dave Westridge >>>>>>

Subject: KR: Composite Fuel Tank Grounding

There was a thread about fuel tank grounding quite a while ago. A friend
loaned me his copy of November's issue of the Light Plane Maintenance
newsletter, which has an article about a product called Thermion that may just
do the trick for composite structural grounding. Thermion is a nickel-coated
carbon fiber weave that is lightweight, transparent, resin compatible, and
electrically conductive. It was originally developed for use in anti-icing
applications, as it's surface heats up when current is applied to the cloth.
The article says it runs about $35 per square yard.

To use this stuff for grounding a fuel tank, you would need to lay it up
between layers of fiberglass, and then electrically connect it to the filler
neck (if yours is metal) and some other place on the tank to attach a
grounding wire when refueling.

You can contact the company directly at:

Maybe I'm missing something, but if fiberglass resin is an insulator, how
can a metal mesh serve as grounding if it's in-between the layers of
fiberglass?  I would think it would have to be partially buried in the
inside layer of resin with at least some of the metal not covered by
resin.  Or can the static discharge go right through fiberglass?

Tim, I may be able to help you out here.  The Lycoming O-290 and O-235
are the exact same engine minus some stroke or bore or both.  The 290 is
a little heavier (245 with electrics) but the center of mass is at the
same location and I am guessing that's what your looking for. The center
of mass for the engine is 8.3 inches forward of the mounting pads and
the minimum distance from the mounting pads to the firewall is 9.5
inches, so what you end up with is about 230 (for the 235) pounds 17.8
inches forward of the firewall. Hope this helps!

PS If you decided to go with a 235 you may want to widen your firewall
by about 3 inches as the Lycs are a little wider than the Continentals
and the extra width makes it easier to blend the cowling with the
fuselage.

I think Mike is on the right track as far as fairing the gear legs on

showing relative drag of different forms/shapes.  Taking a round tube 
shape and fairing it, even adding a "vee" shape to the trailing edge 
only, reduced the drag tremendously.  Those big legs out in the breeze 
can use a little help.

Not only that, but the wide fairings will give Mike some billboard space

I tried to make my own canopy.  I have a bit of advice.  The temperature
control while you heat your plastic seems to be critical.  If the
temperature distribution across your sheet is non-uniform, then it will
bend  and flow in an unpredictable manner.  It is my opinion that the
cost associated with making a good oven make this uneconomical.

Which type? the article says you now have up to 4 possibilities.(not

Hi Richard.

Thanks for the posting. The FAA encourages the widest dissemination of 
its information by any/all means possible, so don't worry about 
copyright infringement.

A couple of things come to mind.

First and most obvious is the fact that most KRs are being pulled around 
with VW engines, engines which were designed to run on AutoGa. So I 
wouldn't worry a heck of a lot, UNLESS you were planning on storing the 
little bird for an extended length of time. Storage is the biggest enemy 
of gas powered vehicles of any kind, from lawn mowers to aircraft, 
because prolonged storage with a little gas in the system generally 
produces a gummy mess (which the article noted).

Second, the article was pointed primarily at certificated aircraft 
engines (Lycomings, Continentals, etc) with an STC (Supplemental Type 
Certificate), noting that many STCs were issued before RFG (ReFormulated 
Gasoline) appeared on the market. They're right. I don't know about 
others, but I am certainly ask around and find out what kind of gasoline 
is being pumped at the local stations in my area, 'cause my STC was 
issued about 9 years ago.

Thanks again for the posting of this information. It was very 
informative and greatly appreciated.

Subject: KR: Auto gasoline additives.

G'Day Netters

This relates to the many questions about mogas in 
planes.  The basic problem is this.  The regions in which
they legislated that oxygen-bearing compounds be included
in gasoline are the ones o greatest concern, along with those
who wish to use the higher octane rating fuel.
Oxygen-bearing compounds were alcohols such as methanol
(the nondrinkable)and ethanol (the drinkable, when pure).
They can attack brass parts (and I believe some pot metals).
Then, along came MTBE and its sister.  These are infinitely
soluble in gasoline BUT they are also very soluble in water
and are NOT good for drinking.  This solubility means that
leaks in filling station tanks are not good.  The gasoline components
tend to float on the subsurfact water and stay nearer the
leaking tank.  MTBE will diffuse out of the gasoline and
dissolve in the water and now has regulatory people some
concerned about danger to the public.  Don't have any recent
information about MTBE effects on fuel system parts.

The important part is that service stations are SUPPOSED to 
keep MSDS sheets on what they distribute onhand at all
times.  The MSDS sheets (Material Specification Data Sheets)
should tell every compound in the fuel.  This should tell you
about the things that might worry you.  Don't hesitate to ask
to see them. 

Until recently, about the only gasoline around central Oklahoma
that was clear of the baddies was Total unleaded regular.  Haven't
checked recently.  I use 1 gal. 100 LL to every 3 gal. regular
unleaded in my T-Craft A-75, for the octane boost as well as
a bit of lead for valve condition.  No problems in 7 years.

Check out the MSDS even if you have to ask a chemist or
Chem Eng what it means.

Well, that depends on the adults.  My wife & I fit fine (stock KR2)
without twisting.  It does feel a bit too snug for long flights though. 
I'm a standard 165 lbs., 5'-9" , she's a little smaller.  And yes, she is
an adult now, honest.

Subject: KR: Canoopy contours

G'Day Netters

I have been very interested in the mail regarding canopies
for widened 2S fuselages.  Why?  See following.

I am completing the scrap lumber mockup of my 2S cockpit
in the garage attic.  The wood looks crummy, but the dimensions
are correct. 
The following changes are embodied in it:
     The outside width  is 41 in. at the panel crossmember
                                       41 in. at the seat back.
                                      42 in. at the shoulders.
     This is the same as my T-Craft and a Yankee at D.J.Perry.  Since
the structure of the 2S is not as thick in this area, it will provide 
a tiny bit more room. But, get two 200 pounders in any of them
and it will be cozy.

Also, in my mockup, the sides are vertical (that is, the cross 
section is a rectangle) at these three stations.  And, the top
of the top longeron is level at 20.25 inches from the deck from
the firewall through Station I.

Will take some pictures before Christmas and send them to someone
who can scan and post them.

I hope someone might be able to locate Three-axis views of 
D'Fly, Yankee and other canopies that would work for 42" wide
fuselages and post them or send them to me for posting, since
this is relatively new KR territory.

What are you considering  "new KR territory"?  To my knowledge there are
at least a dozen KR2 and KR2S models flying with Dragonfly canopies.
Also Mark Langford has a CAD version of the Dragonfly canopy somewhere
in his web site.

I think it's either under "front deck", "aft deck" or "canopy frame" on my
web site (at the URL in my signature).  If I ever get back from Wales (and
somebody reminds me), I'll try to do a detailed drawing for a D'fly canopy.
That was a real pain for me, as the manufacturer in CA didn't wan't to give
away "confidential" information, and RR was not much help either.  The
canopy ordeal is when I decided I'd deciminate as much info on KR2S
construction as humanly possible.  The real breath of fresh air was from
Viking Aircraft, who not only sent as many dimensions as you could ask for
(without a CAD file), but the manual on its installation as well.  To top it
all off, there was only a $63 shipping charge on the $420 canopy... all the
way to Alabama. It's good to hear the price is still essentially the same.
It seems that good will from an aircraft manufacturer usually has a way of
finding it's way back home...

If anyone is considering the Dragonfly Canopy I recommend that you order
it through Viking Aircraft.  The price is the same as buying direct BUT
Viking orders are processed way before individual orders so you will
more than likely receive your canopy much quicker.  To top it off the
Viking people (Pat Taylor and wife) are good people.

Hello fellow KR builders. I have just come on the net but I am in the final
stages of my KR2. I am curious if anyone has any info regarding using a two
bladed Warp Drive, ground adjustable prop. I have one on my plane and have
test run the engine about 1 hour. It ran ran very smooth and quiet. I was told
that Steve Bennett reccomends against using a composite prop with a VW engine
(I have an 1835CC VW with electronic ignition). 

If anyone has any experience with this type of prop on a VW engine I would
love to hear it.

 Would only recommend using a 100% wood prop. Steve

Personal opinion only.  Only place for a turbo on a VW or Sub is for
maintaining seal level power at altitued in aircraft applications.  Not
for boosting power.  Steve
