KR> Re: stall speed reduction

[Ed Janssen]

Greg,

Yes, I did mean to say that KRs are certified airplanes.  Actually it's a 
common misnomer.  KRs are certified (issued an airworthiness certificate) in 
the "Experimental Home Built" category.  Aircraft such as Cessnas, Pipers, etc. 
are certified as well, but the correct terminology for them is "Standard 
Category" aircraft.

I'm sure that you mean to say that an airworthiness certificate is issued.
As home built (kits) are not certified.

About 8 years ago, I had asked if I could put on vortex generators or a
cuffed leading edge.  And yes, I could put I had not asked in reference to
an LSA.  It was for improving (shorting) my take off and landing roll.  But
my guess is that the vortex generators would do the same.  A couple of Long
EZE's did this very thing and they both said that they improved their
numbers.  And I would think that VG's would be a lot simpler.

As far as the LSA.  I don't know what that would do for that.  But you could
ask your local DAR.

I'm not sure the FAA would approve that.  I think a "retrofit" would have to
be done before the KR was ever certified.

Perhaps leading edge cuffs could be designed and  retrofitted to a KR

certified aircraft to improve STOL characteristics.

KR> Gathering Countdown

[Mark Jones]

There are only 42 days left till the Gathering.There are only 31 people 
pre-registered. There are only 8 Kr's flying to the Gathering so far. Come on 
guys and get yourself pre-registered and let us know if you are flying your KR 
to the Gathering. Surely there are a lot more than just 31 folks coming to the 
Gathering. Here is the link to pre-register: Click on 
http://www.krgathering.org/ then look in the left column of links and click on 
pre-register.

Thanks

KR> O2 Requirements

[Randy Smith]

I just use an oxygen Bootle from my small torch set with a regulator and the 
tube that goes in my nose. Works great but the Bootle is heavy. I am over 
weight live at sea level plus 850 and work in and out of attics all day so do 
not get much exercise. I need oxygen over 12500 or I get a real headache. When 
I leave home (Fort Worth) I usually do not go around anything except restricted 
airspace. I will climb to clear as a rule. If I wanted to stay low and go 
around I would drive a car on trips.

I always heard the story of how the FAA came up with the requirements
for supplemental oxygen being a middle aged DC-3 crew that was
"observed" during flight at altitude. I can't help but picture a couple
of fifty year old chain smoking guys that hadn't seen the inside of a
gym since they played high school football. We all should know what the
FAR's say and unfortunately in any sort of incident you had better have
followed them to the letter but the actual fact is that oxygen
requirements vary greatly between individuals. 

Since my KR will be turbocharged I will fly at altitude on a regular
basis and will carry supplemental O2, especially since I understand
Aerox debuted a new portable and affordable system at Oshkosh, but I
will also have one of those finger O2/blood analyzers to help me know
when I really need to be on it.

KR> Ol' Blues wheel alignment

[Myron (Dan) Freeman]

Hi guys and girls;



During the take-off roll of Ol' Blues first flight in some time it was
obvious that it wanted to drift to the left very badly (good thing I had a
working rudder this time) so I got busy and checked the wheel alignment and
found that the right wheel was toed-in by 3-3/8 th's inches measured at 10
ft. and the left wheel was toed-out by 1-1/8th inches. No wonder it wanted
to drift left. So I got busy and re-aligned the axles and it now has 1/16 th
to 1/8 th inches toe-in measured at 10 ft. and it is straight on the
fuselage and wheel center line by 1/4 inch.

I was just to tired to do a taxi test today so I'll do it by this week-end
but I'm sure it will be OK now.

I flew a Maule yesterday and it wore me out. I felt like I was driving a
tri-axle dump truck compared to the KR and it was much harder to get in and
out of than the KR.

Looking forward to the Gathering.

Have a great week-end everybody.

KR> O 2

[Eric Evezard]

Hi Netters,
It is surprising to see that some aviators are venturing above 10 000 ft 
without oxygen.The effects are insidious and that feel good feeling can lead to 
disaster.Reaction varies from day to day per person.I have an old WW 11 A8a 
constant flow system in my sailplane,with excellent results.It amazes me that 
America could mass produce,in wartime, these beautifully  made oxygen 
systems.Bought as surplus they were very inexpensive.I would not fly above 20 
000 ft as a diluter demand  pressure system would be better.Even breathing pure 
oxygen, high enough, one could fall unconscious in seconds,if there is no 
pressure to force it into the lungs.
Best Regards,
Eric,
South Africa.

KR> O2 Requirements

[Teate, Stephen]

"By the time you need oxygen you ability to act on that need is
diminished. "

Absolutely correct. That is why I will keep tabs on it with the finger
O2/blood analyzer. Just because you feel good doesn't mean you don't
need it. I have also heard of folks that use O2 just to avoid the
fatigue of flying at altitude that can occur after the flight. This will
all come at some trial and experience but first I start painting this
weekend.

Stephen,

Although there is no one more skeptical of shortcomings of government than I, 
please be cautious.  By the time you need oxygen you ability to act on that 
need is diminished. Be sure to catch it early. Just something to think about.

Split flaps have as much lift as plain flaps...so the drag is free!  That's 
why split flaps are better than a belly board, in my humble opinion, 
allowing slower and therefore safer landing speeds.  The slower stall speed 
they allow also reduces the likelihood of stall/spin accidents during the 
turn to base (assuming the same speeds were used in both cases).   Belly 
boards are easy to implement, and are far better than nothing, but the split 
flap solution is simply better from a landing and stall speed standpoint. 
I've got 800 hours on my split flaps, and I love 'em...
