KR>Vacuum

[Randy Powell]

Has anyone tried to use a Chevy belt driven vacuum pump ?  They are readily 
available, reliable and reasonably compact.  They were used on the Chevy 
pickups with the 6.2 litter diesel engines.   I put well over a 100K miles 
on one with no problems.  They could be belt driven or a coupler could be 
easily made to drive them direct.  Just a thought.

KR> folding wings

[Orma Robbins]

About those folding wing plans.   I Got a set.   Still in the envelope with 
all the ceertified postage stuff.

Every now and then I wake from retirement slumber and reconnect.   While 
looking for other things in my file cabinet, I ran across the set of plans 
that I purchased from the Col back in 91 (You remember back during the gold 
rush).   First thing I went to was the page with the "NOTICE IS HEREBY GIVEN 
THAT THE RIGHTS AND PROTECTIONS AFFORDED TO THE MOORE FOLDING WING KIT & 
PLAN BY LAW IS STRICTLY ENFORCED IF ABRIDGED BY ANY ENTITY7 AND/OR PATENTS 
FOR PROFIT.   EACH ORIGINAL SET OF PLANS WILL BE NUMBERED & SIGNED BY COL. 
R.W. MOORE."

Next comes the Waiver of liability.   In this section he says that if you 
are crazy enough to build and use it don't call him if you get hurt.

Missing is any mention of how many I can make with my LEGAL plans.   How 
many do you guys want., and how much U willing to pay.

Send me the mock up and tell me how many.

PS.   Talk is cheap, I might have to ask one of our legal reps

After rereading Ray's post, I guess I'll take back that I'll document it all
and put it on KRnet.  That's Moore's "iintellectual property", so that
wouldn't be right.  Perhaps he's still on KRnet and would offer those plans.
Maybe the raffle idea for that one setup isn't such a bad idea either.  If
we can't locate him, that may be a different matter, but that's for later.

I just bought a used ICOM IC-91A HT with the Digital Module (DSTAR 
Compatible). I haven't had time to see all its options, but
I'll  let y'all know what I uncover about it and APRS. I know it does 
some form of position reporting with an external GPS input. Its a Dual 
Bander: both 2 meter and 70cm (144MHz and 440MHz). He with the most

KR> PPL Written test

[Glenn Martin]

Well I have made a benchmark today. I took my PPL written test and 
passed with a 97%. Two questions missed..one on ADF..(no biggie) and 
another on SVFR. I added a 1000 foot ceiling to the requirement in class 
C airspace. I had it right to begin with and second guessed myself, but 
I am VERY pleased to have this finished!

KR> APRS/SLOWER LANDING SPEED

[Larry H.]

Too bad we have to worry about even having ELTs. If we can concentrate on 
developing our aircraft with slower, more survivable landing speeds, then the 
correct radio could be used once on the ground to contact the ham guys to come 
and get us. We may have to give up some top speed to have a lot slower landing 
airplane but the trade off might be more comforting while flying over hostile 
terrain. Then there is the airframe failure, landing speed does not matter, a 
parachute would be ones only chance. I suppose a parachute like the Cirrus 
incorporates would be another thing to consider. I do know we have discussed 
that before so go take a look at the opinions on that subject in the archives.
I have noticed the hills and trees below your airplane Mark L in those 
beautiful flying photos. LOL
Around my area there are a lot of flat fields but when flying west the terrain 
gets bad, fly east and miles and miles of forests. I would rather land at 30 
miles per hour in trees or rough terrain than 50 or 60 mph. Maybe then I might 
still be able to call for help or walk away. Someone might know but the human 
body can only take so much, so each 10 mph we can slow landing speed will 
increase our chances of survivability.
A passer by landed here on my airport 15 or 20 years ago. He was flying a 
Cessna 182 and had come here from the Denver CO area to sell his 182 to a 
broker. I took him to my house and offered for him to stay with us but he 
wanted to go to a motel. I took him for dinner and then to the motel and picked 
him up the next day and spent the day with him. We became friends and stayed in 
touch, we wrote regularly. He was building a T18 and was really excited about 
it.
One day when I checked my mail box, there was a letter with his return address 
but it wasn't in his handwriting as usual. I knew immediately before opening 
the envelope that he had been killed. His wife wrote me the letter telling of 
how he got the T18 ready and on one of the first few flights, his engine quit 
just after takeoff. Because of the hostile terrain around there, no place was 
available for him to safely land. At the speed he had to maintain in order to 
prevent a stall, there just was no chance for him to survive. Stories like this 
is what makes me wonder why we do not take more time to explore lower landing 
speeds. I am just as bad as anyone at wanting to have a, as fast as possible, 
airplane but it only takes one miscue to have our wife writing that letter.
As my mother used to tell us while learning to drive and pulling out into 
traffic, "just take your time, because you have a lot more time than lives".

Hi Glenn,
Most of the aviation installed APRS systems use an embedded built in
transmitter, not an external HT.  Check out the links I included in my
previous email for more details.

Good idea to carry the extra HT though (whether it be aviation or Ham
freqs).

Just fyi,

KR> APRS

[Glenn Martin]

Lets not forget also that  there are 2 meter (VHF) and 70cm (UHF) ham 
radio repeaters all over the world, and the same transceiver used for 
APRS  can be used to send a MAYDAY call also. All it takes is adding 
repeater frequencies along the route of your flight plan. I program them 
into my 40 memory Handy-Talky and just go from the lowest to the highest 
memory channel as I travel out (and vs-vs). APRS is great, but Amateur 
Radio offers much more than just that. I highly recommend that everyone 
get a Technician class license and at LEAST a 2 meter HT.

Very good question and the answer is the usual glass half empty or half 
full.

An ELT/PLB is only activated and sends out a position report when you 
have an emergency; if it and or you survived long enough to send out the 
signal.

An APRS is continuously sending out and logging position reports.  No 
one has to be monitoring the APRS reports; so when you are over due your 
track can be called up and your smoking hole will, more than likely, be 
where your course line stops.  This does assume that there is someone 
that is concerned enough about you to be worried when you do not show up 
on time.  If there is no one in that category then I guess it doesn't 
really matter if you are found or not :-P

Yes I am one of the gray haired Hams who had to take the code test to 
get their license (WB9KJW in 1971) and actually have somewhat more faith 
in the APRS system than the the ELT system.

KR>Vacuum

[MVS Knight]

Glenn,



My dad's old KR-2S started out using a venturi that was mounted on the bottom 
of the fuse between the main gear to drive the attitude indicator and the DG. 
It worked, but only barley put out enough vac to get the AI to indicate right 
after about 10 min of flight time. This is obviously not ideal, and besides, 
the venturi on the bottom looked terrible!

Later on, he machined a mounting plate and a belt drive to run a normal 
aircraft vac pump off the Revmaster 2180 and that worked like a charm. I'm not 
sure how he did it, but I could get you his email if you'd like to ask.



BTW, this is my first post to the list! I'd like to say hello to everyone. I'm 
beginning the build on a KR-2S in Palmetto GA at my house. Thanks to everyone 
for the good information here and I look forward to meeting many of you at the 
next gathering that I plan on attending.

KR> Mending a wing tank leak

[phillip matheson]

I wrote a week ago about my wheel bearing adjustment problem, Well I also 
had a fuel smell in the cabin, and when I checked it out, I found a small 
leak in the R outer wing tank, it was weeping into the WAF area, thus the 
fumes leaked into the cabin via the inner wing.


I borrowed a 5 inch hole saw and cut into the bottom of the tank.
I took photo's but seeing my web page is down I can not post them.

I found a small area I believed to be leaking, but not sure, so I painted 
the complete inside of the fuel tank I could reach via the 5 inch hole.

That was easy, but I could not decide how to fix thew 5 inch hole.
I had a brain snap. I laid 3 lays of 5oz cloth larger than the 5 inch hole, 
on a flat surface.

When dry, I cut a circle 7 inch diameter. I then cut a 1 inch hole in the 
centre to fit my finger through.
>From underneath the wing I reached inside the tank and wet around the cut 
out with flox.
I flexed the 7 inch circle to fit through the 5 inch hole, then using the 
finger hole I turned the disc around to embed it into the wet flox.

When dry, I turned the wing over, I put more flox onto of the disc, which 
stops the cut out from falling into the tank. The wet flox oozed out the gap 
made by the hole saw, and that was it.

I wiped off all the wet flox, when dry all I had was a nice neat 1/8 thick x 
5 inch circle on the bottom of the wing that I will paint one day.

Hope you can follow all that. Do not be afraid to have ago. It is only 
glass, easy to fix.

Gusset , but I think I trimmed a small section from the 1/4" spruce that the

I will be flying in the morning, I will try and take a photo.

Remember to ask me how I mended a leak in my R glass fuel tank. I will be 
testing that tomorrow. ( I will try and write something now and post

Hi guys, my 2 cents worth.
I made my bracket from T6 flat. I bent it to the correct angle, as close to
rear spar as possible.
I welded a gusset on the underside,( so it looks like a "T" section. very
strong and light.
