I looked at the new web site and it seems Steve is off to a good start. 
I would not worry about getting the plans from Jeanette Rand, as she has 
NOT, to my knowledge, ever shorted anyone( and i've been aware of the KR 
since 1979). It took a short period to get MY plans from her; about 4 
weeks (although i will say I was fortunate enough to get to actually 
talk to her :-)). Jeanette seems affable and honest. She should be 
commended for supporting the KR2 community all these years. I hope that 
in Steve Glovers company, perhaps the torch has been passed to a person 
who will keep it going. I cant see where Ms Rand made a great deal off 
of the KR series anyway, so we should thank her for the many sets of 
plans she shipped all these years. Lets play nice, folks! Patience is a 
necessity, especially when building a plane!

Dave
Roy Szarafinski, rvick...@yahoo.com, has a Harley throttlebody that I had 
bought to possibly use on my Corvair. He was going to toy it as he thought it 
really had possibilities. I'm not sure if he has done anything with it yet. He 
also has a throttlebody of his own design that he has run on the Corvair on his 
Zenith 701 project.
Mark Langford, n5...@hiwaay.net, also has the same throttlebody unit and was 
considering using it on engine someday. Robert Haines has also done work with a 
H-D throttlebody. Check his website www.hainesengineering.com/rhaines to see 
his work. Keep me posted if you decide to use an H-D throttlebody. My project 
is a couple of years away from needing an engine.

I know those members of this group who know her have a lot of affection for
Jeanette Rand, but for those of us who don't know her, particularly those
who are overseas, it is very frustrating.  I had the same experience, months
of unreturned calls, no response to faxes, etc. so I gave up.  I was
fortunate enough subsequently to find someone selling an unused set of plans
so I'm still on the path, but I can certainly understand those who have
decided to look elsewhere for the aircraft of their dreams.

The recent initiative by Steve Glover looks like being a huge step forward
in terms of being able to undertake 'normal' commercial transactions and get
some commercial support for those who feel they need it.  I wish Steve well
in his endeavour.

Hi guys!  You may not remember me but I went to the KR gathering in Colombia 
Tennessee and started this project shortly after that. I am now moving in a 
month and have had health problems so I can only get my medical on special 
issuance. SoI'm selling my project that I loved so dearly. Hope to find it 
a good home with someone who will finish and fly it.

KR2S  Homebuilt Experimental Airplane Project For Sale  12/15/09
Spruce/aircraft ply/fiberglass composite  


I have done much of the hard work. Now all you have to do is finish it and fly 
it. I am a perfectionist and a skilled builder. This KR has been built to my 
high standards so you can feel confident about the craftsmanship. The project 
is beautifully constructed so far. I have maintained logbooks and test samples 
on this project.  I?m moving and have medical problems so it doesn?t make sense 
for me to finish this project. Just looking at what I am selling you may not 
realize all the hours and work it took to construct it to this stage. Each 
section is  assembled with the correct shape and very tight tolerances. No 
warps or misalignments. Everything is straight, true and strong. I have used 
T88 epoxy adhesive (considered the best) to construct the spruce/ply and 
aeropoxy for the fiberglass surfaces. All double-taper wing spars are 
completely assembled . The RR plans have been followed  except for two 
modifications. To improve shoulder room. I widened
 the fuselage a little (one inch). And to improve pitch stability, I widened 
the horizontal stabilizer (and elevator) by 3 inches per side. Includes a 
Dragonfly canopy that is aerodynamically very sleek. Includes many assembled 
components. An engine and gear are not included.  Right now I'd like to sell it 
as an entire project, but may consider selling off the pieces later.

Here's what I have into it: Complete aircraft spruce/ply kit, T88 $1500, wing 
attach fittings $450, hinges,foam, fiberglass,fillers, epoxy, hardware $500, 
Canopy, canopy frame, forward deck $700, Plans $240, and lots and lots of 
manhours. Total about $3390 in parts alone. Im adding $1000 in labor (a big 
bargain). Total asking price is $4390 for the project with many assembled 
sections. Reasonable offers will be considered.   Photos available. Email me at 
rsmith...@nycap.rr.com for info or photos.  Location is Ballston lake, NY  (20N 
of Albany). Tel ?Bob? at 518 8776056

This project now consists of:

Rand Robinson KR2S plans 
Rand Robinson KR2S builders instruction book
Complete set of spruce from Wicks (set used to construct sections listed below)
Fuselage near completion with aircraft mahogany plywood
Composite Fiberglass/foam horizontal stabilizer near completion w hinges
Composite fiberglass/foam elevator with carbon-fiber reinforced sharp edges 
near  completion w hinges
Composite fiberglass/foam vertical stabilizer near completion
Composite fiberglass/foam rudder
Complete set of (2) fore and aft main box wing spars completed and looking 
beautiful and strong.(not yet drilled)
Complete set of (4) outer double tapered wing spars completed (not yet drilled)
Complete set of 16 laser cut, powder coated wing attach fittings
Optical quality, very aerodynamic acrylic canopy (Dragonfly model)
2 fiberglass composite bulkheads (1 for the canopy, one for the aft section)
2 composite canopy frame supports
1 composite fiberglass/foam forward deck
Polyurethane foam, 2 boxes
½ inch urethane foam sheets, 1 box
Polyethylene foam, 1 section
¼ inch aircraft plywood for firewall
1/8 inch aircraft ply for flooring
Radio antenna and coax (for Vstab)
Various aircraft-grade hardware
Leftover mahogany aircraft plywood
Fiberglass cloth in various thicknesses, approx 4 rolls
Carbon fiber reinforcement cloth
An instrument panel template
Loads of printed Krnet helpful hints

And hidden deep inside the main spar is a tiny bird's "feather" to give the 
project the right karma.
I think this project is less than 50% completed so you can be the builder.

I also have pieces of aircraft steel for wing attach fittings if you want to 
make your own. Already cut to width. Make me an offer. Will sell separately

KR> Aeropoxy

2009-12-17 Thread ttcse/Tom
Hi John,  Let Me try it. 
 
Let me try it.  I've been a member of composite airplane forums for years and 
have hundreds of dollar$ of Aeropoxy in a storage unit.  At least one 
contributing member of those forums has substantial work in the epoxy 
manufacturing and evaluating field. 
 
If low temps are the only issue, it is not ruined.  It's just waiting for 
appropriate temps to finish curing.   It doesn't spoil. 
 
Low temperature will slow and/or stop the curing process until the temp warms 
up to around 100 + something degrees.   Once the temps hit those temperatures 
it'll finish curing and developing it's max strength.  
 
(To exotherm is not  normally a good thing.  You get this from an excessive 
quantity of mixed goo and the stuff can actually get hot enough to 
self-ignite.) 
 
Always a possibility is to wonder if you mixed the ratio backwards.  Rather 
than x-amount of resin and y-amount of hardner,  you did y-amount of resin and 
x-amount of hardner.  
 
While Rutan taught composite guys to mix for at least 3 minutes, scraping the 
sides and bottoms of the cup and all,  I'm aware of many guys who mixed for 
much less than Rutan recommendations and flew their airplanes for years. 
 
I'd say, get your temps up and see what develops.

Steve Glover of nVaero is now distributing the KR plans and parts.  I am
sure Steve will quickly take care of your situation now that he is aware of
it.  I got my plans about a week after I ordered them from nVareo.  They
take credit card payment and have email confirmation as well as shipment

The main nVaero website can be found at: www.*nvaero*.com.  They even have a

Aeropoxy doesn't cure very fast below 70F, and certainly not in the lower 
60's.  Heat it up to 78F or so and it'll probably finish curing in a few 
hours.  The tacky places you found are probably thinner areas where there 
wasn't enough volume in one place to go exothermic and warm the stuff up to 
the point of curing.  Trying warming it all up, and I'll bet it'll be fine. 
But if it's been above 75 or so for days and is still tacky, you probably 
have other problems as mentioned by Ron.  Aeropoxy doesn't usually have any 
kind of tacky film on the surface though.

KR> Aeropoxy

2009-12-17 Thread Ronald Piekaar
Hi John,
The usual suspects for uncured area of epoxy are inadequate mixing, 
expired shelf life, surface contamination or incompatibility with 
something in the substrate. Assuming none of these, the epoxy should 
cure at 64 degrees as witnessed by the fact that some of it did which 
left you with a few localized problems rather than a generalized 
problem. Try wiping the tacky areas with lacquer thinner to see if 
those areas are completely uncured or if the tackiness is merely a 
surface anomaly. If the areas are completely uncured I would suspect a 
mixing problem which would require a thorough cleaning (lacquer 
thinner, MEK, etc.) and patching of those areas. If the problem is a 
surface problem and the area is cured below a thin film of surface 
tackiness, clean the film thoroughly and you should be good to go. I 
would then call tech. serv. for Aeropoxy to prevent any further 
occurrences. Good Luck.

KR> Battery type

2009-12-17 Thread Paul & Karen Smith
The major difference between aircraft and auto batteries is the plate
design.
(among other things like robust construction and longer shelf life) 

You see cars tend to do frequent starts and short recharge times (down the
corner
shop for a pint of milk) but don't need to run very long if the alternator
dies.
Airplanes start less frequently and generally run for a good while when they
do
but absolutely need the best life if the alternator fails.

In the July'09 Kitplanes this is described in detail.

Aircraft batteries have thick plates for sustained current draw (0.1") but
may
suffer in the cranking department. 
Auto batteries have larger, thinner plates (0.05") for massive cranking
current
but suffer in the long draw department

Therefore aircraft batteries have relatively higher Amp-Hour (AH) rating
Auto batteries have a relatively higher cranking current rating.

This is not to say not to use auto batteries but please understand the
benefits
and limitations. IFR or highly electric planes should really use an aircraft
battery
or at least have a backup (as I will be doing) Aircraft that use
predominantly
steam gauges, gravity fed fuel and magnetos can get away with an auto
battery.
