KR> Ethanol

[Chris Prata]

my FIRST thought upon reading that (besides how interesting it is) is what does 
this mean for E90 from the local Shell station because, economically, thats the 
cheapest to run.  I then think of "vapor lock" which seems to be the primary 
concern, followed by water absorption and corrosion. 
I am not talking about the primary topic of course which is E100... because 
thats hard to get

I always thought to run 100ll in one tank for takeoff and approach/landing, and 
E90 in the working tank which would be drained into my car after flight.

KR> Ethanol

[andrew]

Here goes the spoon feed ?Don?t use it?.

 As I?m working on blue prints for the KRSuper1, and getting my outside 
research done. I am settled on one huge taboo of the aviation community. This 
bad boy is going to be tuned and built to run primarily on ethanol.

?But Cessna and the big aviation companies says it?s horrible.? Hold on and let 
me get some hand on acknowledge your way.

Dr. Maxwell Schauck has been flying on ethanol since the 1980?s, and flew 
across the Atlantic in his Velocity back in 1989. While I was attending his 
program at Baylor University I got to participate in his research for 4 years. 
In that four years I came to find out a few things.

1. Ethanol is a superior fuel to 100LL.
2. Oil companies will do everything to keep it out of mainstream use
3. Ethanol has a natural octane of 113
4. Ethanol burns cooler, and will run smooth at 50 degrees past peak EGT
5. If you add water, you get a horsepower boost, AND you don?t have to worry 
about it damaging your engine
6. Ethanol reduces engine vibrations by 50%.
7. Ethanol doesn?t react with oil in the same manor as 100ll or mogas
8. Ethanol will eat aluminum and natural rubber. Easily combated by anodizing 
and using Teflon
9. If an engine is tuned to ethanol vs. 100LL, you get a significant horsepower 
boost with minimal GPH increase.

This is all based on my personal experience working on our departments Pitts 
S2B, Cessna 152, Cessna 172, Velocity, Piper Aztec, and Max Performance 
Research aircraft prototype. We averaged a horsepower increase of roughly 
30-35% increase with ethanol vs. avgas, with no changes to the mechanical 
tuning on the engine. To the point we had to order custom props for all our 
aircraft, due to engine overspeed with the standard propellers. (The Pitts S2B 
ran 300HP on 100LL and 350HP on ethanol).

We also did water in fuel testing for the FAA while getting our Cessna?s STCs 
updated (yes, Dr. Schauck owns the STCs for 152s and 172s to be flown on 100% 
ethanol in utility category). We were able to add 10% water to the fuel tanks 
before reaching peak EGTs. Had we tuned the engine this percentage would have 
gone up.

So why am I sharing; I plan on building the first KR that is designed to fly on 
ethanol. And foreseeing the usual arguments I figured I would head off most 
prior to having to repeat. 

So a Corvair with 100HP should obtain 130HP simply by tuning to run on the 113 
Octane ethanol. But we shall see when we get to that part of my build.

What are your thoughts on the matter?

KR> Cleveland Brakes with DOT 3

[Chris Kinnaman]

DOT 5 is not exactly compatible with the stock rubber components of 
motorcycle braking systems. The seals and o-rings will not break down or 
deteriorate, but they will drag in the bores of the calipers and 
cylinders. This in turn leads to the pucks dragging on the discs because 
the pistons don't retract. If you use DOT 5 the rubber items need to be 
replaced with a rubber that is designed to work with DOT 5. DOT 5 was 
touted in all the magazines for its resistance to heat but in practice 
it caused me nothing but trouble. The big issue with DOT 3 is that it is 
hygroscopic. Change it out once a year and you're good. Braking a KR 
will never stress brake fluid nearly as much as road racing a motorcycle 
and I used DOT 3 in all my endurance race bikes. It was good for an 
entire season.

KR> Cleavland Brakes with DOT 3

They can if you change the caliper o-rings to something like EPDM, which 
is compatible with DOT3.  They come with o-rings compatible with 
aircraft hydraulic oil.  It's a pretty simple matter to replace the 
o-rings, which are a standard size and encircle each caliper.

See the fluid compatibility chart at
  http://www.marcorubber.com/compatibility.htm and search for "brake" 
and you'll find several options that will work.

KR> Trying to find someone local.

[codylee.cramer]

I live in middleburg. I would love to come pick your brain alittle bit. I am 
looking for interior setups mainly. Along with landing gears and the routing of 
some control cables. I just sent my case out to great Plains for machine work. 
It shouldn't be long before I have a flying kr. I am free today and most of the 
day tomorrow before I get back on a plane for work. 904-402-5406.

Where are you?? I live at an air park in Green Cove now, but still work
in Jacksonville.? I don't have a KR anymore, but I have had at least a
half dozen in the past.? There are three KRs at my airpark, but none
currently flying.

I have a kr2 airframe that has been completely gutted (for the most
part). I am trying to find someone local or within an hour range of
jacksonville, Florida that has a completed kr2 that would allow me to
look over their plane to figure some things out on mine. Any help would
be greatly appreciated. Thank you.

KR> Fuselage sides vertical?

[Dan Heath]

I have always thought that an all wood KR would be pretty great.  Also, I do
have to admit, I like the banana boat shape of the KR.  It just needs to be
a little more wide at the shoulders to be a decent 2 place airplane.
