Hi everyone.
I just recieved a Revmaster 2100D today. The engine appears to be in
excellent condition. I am wondering if any of you fly with this motor and
if so what carb and size do you use??
  Thank You.

He's flown his KR from UK across the Atlantic -via Iceland and Greenland
-and now he's half way down the west coast of Russia.

I'm going long periods without mustering the enthusiasm needed to
maintain and fly the aircraft so I've put this wonderful plane back on
Barnstormers, where I found it in 2006.  We've seen even the most
enthusiastic KR people decide to do something else - Jim Faughn comes to
mind - but there are many on that list if you think back.  Now I'm
joining them, sad to say.

Flying; a few flights to log in on my 31st year on my KR2 N39426. Yesterday?s 
flight was around the John Day valley. I saw 178mph on the GPS; not level 
flight but shallow power on dissent over a friend?s place (I keep  at least 
1000? between me and the ground). About 140mph is my cruise at less than full 
throttle, with most of my flying at 5,000 to 7,000 feet above sea level.

Thought I was going to have to give it up, 3rd class physical in September, new 
doctor picked up a heart murmur and failed me on my hearing test. At the FAA?s 
request I had to have an echo cardiogram and hearing test, passed with flying 
colors. Didn?t hear back from FAA . Wife called them in early February, the 
young sweet lady who answered said ?he is cleared to fly?. The FAA mailed my 
Medical  Certificate on December 4th, but was returned ?undeliverable?; mailed 
to my street address instead of my post office box! So going on my 78th year on 
earth all is well.

 I always wondered about the holes in a belly board.  The T-28s I flew 
had them on the belly mounted speed brake that was flush with the 
fuselage when retracted.  I could only imagine that the holes gave it 
greater drag because of conflicting vortices generated by the holes.

At the KR gathering, I noticed that our British friend had holes in his 
belly board.

I've noticed that the speed brakes on jets don't have the holes. Even 
retracted, they cause some disruption of the airflow because the surface 
is not smooth because of the holes.  At the higher speeds of jets, since 
parasitic drag goes up as the square of the speed, holes like that could 
significantly add drag.  A T-28 usually cruised at about 200mph.  That's 
just about the approach speed of jets.

Of course, as home builders, by using foam and fiberglass, bumps made on 
the belly could fill the holes retracted, but at the speeds of a KR, the 
drag caused by the retracted speed brake may not be significant.

I've asked this before and never got an answer.  For youvwho are running VW
based engines in your kr, is anyone using a Marvel-Schebler or Stromberg
carbs?  Now for the opinion portion of the show...would it be reasonable to
assume that a MS carb designed for a particular engine be usable on another
engine of a different mfg with similar HP and performance?

KR> Part 1 - Flutter

[sparksfly2ms at cox.net]

Hey Scott, I can relate to this one as, same thing happened to me many years 
ago when the cable attach at the control arm broke due to being rusted away
on a Fly Baby I was flying. Glad I was on down wind when it happened and was 
a handful but, made it down OK.Sparky Sparks

Subject: KR> Part 1 - Flutter

Things have been a bit quiet on here for a while, so I'll relate a couple of 
stories I was involved in a couple of weeks ago.

Part 1 - Flutter

I flew my SuperCub to Casa Grande, AZ for the Copperstate Fly In a couple of 
weeks ago.  Note that my SuperCub is amateur built and has a trim tab on the 
elevator (like our KRs) rather than a jackscrew for the horizontal 
stabilizer like a Piper Cub.  I came as close to having to make a forced 
landing as I ever have in 38 years and several thousand hours. I was doing a 
nice down hill descent towards St Johns, AZ with lots of nose down trim when 
suddenly the elevator went into a violent flutter. At first I thought I has 
thrown a prop tip. Then I noticed the engine seemed to be OK, but all the 
violent action was happening in the tail and was being transmitter through 
the control stick. I slowed to MCA (which is pretty darned slow in a Cub), 
but that didn't seem to help. I had concluded a failure in the tail was 
imminent and was setting up to make a forced landing.  My non-pilot 
passenger in the rear seat suggested I try pulling in the flaps to see if 
that would make any difference in the ongoing flutter.  I pulled in full 
flaps, which seemed to reduce the frequency and amplitude of the flutter, 
although it was still quite violent.  I decided to press on another 6 miles 
to the airport flying at fence top level.  Short version of the story is 
that I landed successfully at the airport.

So what happened?  My elevator trim tab was designed using a single 
push/pull bowden cable connected to an overhead lever in the cockpit, much 
like the Aeroncas.  When flying with nose down trim, the trim tab is pushed 
up a bit more than the elevator.  I remember feeling an odd back and forth 
motion in the stick which turned out to be the trim tab working up and down. 
The bowden cable that was pushing on the trim tab eventually work hardened 
and broke at the trim tab.  This allowed the trim tab to go into flutter. 
The trim tab flutter acted like a servo and drove the elevator into a 
sympathetic flutter.  It was violent enough that you could see the shock 
waves from the flutter propagating down the length of the lift struts and 
wings.  Half of the rivets holding the trim tab to the elevator had also 
failed while the tab was fluttering.  I was able to locate a new core for 
the bowden cable and the rivets to re-attach the trim tab in a town about 30 
miles away.  I send a friend to pick up parts for me in his speedy RV-8 
while I inspected the Cub for cracks and damage.

I found no cracks or damage, and my friend in his speedy RV was back in a 
flash with parts in hand.  An hour and a half later, the Cub was repaired, a 
test flight was performed, and I was on my way.  Then more issues arose that 
I'll write about in part 2.

Lesson learned.  I looked at several Aeroncas while at Copperstate.  They 
didn't use a push/pull bowden cable like I thought.  They used two lighter 
cables in a pull/pull arrangement for trim.  In fact walking around the ramp 
at the fly-in, I found no planes with a push/pull cable, although a number 
have a push pull trim with a Ray Allen servo and threaded rod (like I have 
in my KR).  The trim cable will be removed and electric trim servo installed 
in the near future.  In the mean time, I don't trim the Cub nose down for a 
speedy descent.  Speedy in the Cub is still painfully slow anyway. :o)

Part 2 coming up this evening...
