John,

I have a RayJay turbo on my Kr-2 (N54PB 1835 VW), sorry, I do NOT have a waste 
Gate on the setup.  The individual who built the engine, along with help from 
his Toyota auto engineers who worked for him, sized the turbo housing to 
eliminate the over boosting problem.

I keep an eye on the manifold pressure when applying full throttle and in the 
past, the problem was not being able to get enough boost to maintain sea level 
pressure. I did get more performance out of the turbo once I straightened out 
the air intake.  I eliminated most of the numerous bends and direction changes 
in the original air intake plumbing.

Sounds like I have the similar intake setup as you mentioned, ie the carburetor 
is BEFORE the turbo.


Sorry I am not able to give you any advice about a waste gate operation, let me 
know if I can provide any other advice to help you get your bird into the air.

Re: KR> KRnet Digest, Vol 9, Issue 17

[Parley T Byington via KRnet]

Mark;

I have had to remove my force one hub on my 1835 Turbo VW a couple of times in 
the past.

I built a puller out of .25 inch steal that had the prop hub bolt pattern on 
one end and a hole in the center large enough for the hydraulic jack ram to fit 
against the hub bolt.

I bolted the puller to the prop hub using all six prop holes and a half round 
backup steel plates to reinforce the force one prop hub and placed the 12 ton 
hydraulic jack in the middle of the steel puller box, that I had welded up, and 
then loosened the prop shaft center bolt several turns to give some clearance 
and then used the jack to press the hub off the crank shaft.

The hubs require a large amount of pressure to press them off and this set up 
does a nice job, be prepared for the hub to ALL OF A SUDDEN POP with a LOUD 
bang when it lets go!  Otherwise it will scare the devil out of you!

Hope this info helps!

Re: KR> KR Landing in Tacoma Washington

[Parley T Byington via KRnet]

I noticed that it appears that his engine, indeed, was dead ie the prop was not 
turning in the video as the officer was facing the aircraft on approach.

Under the circumstances, I think the pilot did an excellent job avoiding a 
crash and the cars on the road.  Notice in the video how he avoided the street 
lights, and the on coming cars, the car stopped at the red light.  I noticed he 
was side slipping as he descended and prior to that he was more than likely 
trying to keep his airspeed to enable last minute maneuvering.  

I believe, that some may think this was a bad landing because the pilot forced 
the touch down and bounced as a result, however, I will remind everyone that 
this pilot was trying to get down and STOPPED before the intersection as well 
as avoid the obstacles including civilians in cars and sidewalks!

As a Kr2 pilot myself, and owning N54PB, which is a conventional kr2 with 
retracts and NO flaps or belly board, I think NO ONE can fault this pilot on 
his EMERGENCY landing!

I also think that the police officer did a GREAT job HELPING the pilot and 
protecting the public by his quick thinking and reaction to this EMERGENCY!  
This officer took the phrase/motto “To protect and serve” literally and did a 
great job, we need more of his kind.

Re: KR> Stick & Rudder

[Parley T Byington via KRnet]

For all those who do NOT believe in the Bernoulli theory, I would suggest you 
try this simple experiment:  take an ordinary teaspoon and dangle it from the 
handle so that the curved surface just comes in contact with a stream of 
running water and watch what happens.  Yes water is much more dense than air 
but the principle is the same with a airfoil.  The difference is that the 
median that it is traveling through, air versus water, is much thinner and 
therefor has to be moving faster to achieve the equivalent force.

Yes there is some lift created due to the angle of incidence and the resulting 
downward deflection (this is one of the causes of what is called “ ROUND 
EFFECT”) of air produced due to the forward movement of said airfoil through 
that median BUT the vast majority of the lift created is due to the 
differential in air pressure that is created due to Bernoulli’s theory.

Aircraft produce lift and thus fly due to displacing their weight in air just 
like a ship floats by displacing it’s weight in water.  A two thousand pound 
boat has to displace 2000 pounds of water in order to stay on top of the water 
and an aircraft has to displace the equivalent amount of air as it’s weight in 
order to maintain or achieve bouncy in the air.  As a boat moves through water 
it produces a wake which is nothing more than the water that was displaced by 
said boat returning to its natural state of equilibrium once the boat has 
passed.  An aircraft also produces a wake and it is evident by the wingtip 
vortices created at the wing tips as the air pressure flows from the high 
pressure side of the wing, the bottom, around the tip to the low pressure side 
of the wing, the top.

This explanation also explains why we feel a bump every time we fly through a 
cloud, the cloud is LESS dense than the air around it and thus can NOT support 
the same amount of weight given the same numbers of speed, weight, angle of 
attack and drag that the aircraft was using and in equilibrium prior to 
entering said cloud.

As far as thinking that flight simulators are not valid or are useless in 
training pilots, I beg to differ with that idea all together.  I personally 
have well over 4000 hours in flight simulators of various makes and models, 
mostly the F4 but also B-27, DC-9, DC-8, L-1011, B-757, T-38, and T-37 types.  
I know of many times that pilots were able to save both themselves and their 
aircraft due to the things they learned while practicing in simulators.  Most 
pilots that have the opportunity to fly these magnificent "Pretend aircraft", 
take the opportunity to try things that they would NOT dare try in the REAL 
aircraft and by doing so, learn what most likely will happen in that particular 
circumstance.

This is only my $.02 worth on this subject, but I do have a commercial license 
and have been flying since 1974. I have flown many different types of REAL 
aircraft as well as the full motion simulators that I mentioned, have built and 
flown my own KR-2 and helped others build a Fokker DR1 triplane, a Vari-Eze, a 
Vans RV 6, and a Rans S-7.

My comments are NOT meant to belittle, criticize, or in any way show how smart 
I am or how dumb anyone else is.  Otherwise my comments are NOT meant to OFFEND 
anyone, I enjoy reading all comments and ideas about flying from the vast 
number of fellow pilots out there, they are very educational and I have learned 
much from them, THANK YOU all for your contributions to this forum.

I hope this comment gives my fellow KR pilots some more information that will 
help or at least spark further thought on how our heavier than air creations 
actually take off, maintain and then come back down, SAFELY.

Re: KR> Green Foam Board

Ken;

Just cut a piece off and compare the outside color to the middle of the same 
piece, the sun would not have gotten to the inside of the foam.  I would NOT be 
afraid of using the foam because again it is NOT intended to be structural only 
to hold the shape as a mold for the fiberglass.

Re: KR> Green Foam Board

[Parley T Byington via KRnet]

That is normal for the green foam used on the KR-2, it sands super easy, it is 
brittle and it should be fine.  

The only thing that will cause it to deteriorate is if it has been left out in 
the direct sunlight, which will cause it to change color.

The strength is in the fiberglass, the foam just creates a form to shape the 
layups, it adds little to the structural strength overall.

Hope it helps.

Re: KR> I have this green foam board...

[Parley T Byington via KRnet]

Virgil;

That foam is Urethane foam and was what most early KRs were made with.  

The wing ribs as well as the surface are formed from this easily sanded foam.  
One caution I would advise anyone who uses this type of foam is to be SURE AND 
WEAR a face mask to keep the sanding foam out of YOUR LUNGS!  Also this type of 
foam produces syanide (sic) gas when burned!

My wings and most of the molds used on my kr-2 was created using this type of 
foam.

Re: KR> airport selection

[Parley T Byington via KRnet]

I would NOT use a short narrow strip for my first flight in the KR-2.  

First: this is a NEW aircraft and possibly an inexperienced KR pilot couple 
those two factors with the good possibilities of something mechanically going 
wrong and you are setting yourself up for a disaster which may cost you your 
life.

Second: You will have enough to worry about learning the characteristics of a 
new airplane that you are not familiar with without having to worry about take 
off distance, or keeping everything going perfectly straight down the short 
runway.

Third: Why take the added risk of a marginal runway length and width when there 
are many other better suited test areas to use?  Don’t know what part of the 
country you are located in but here in southern Nevada, there are plenty of dry 
lakes where testing new aircraft is much safer and less chance of damaging 
private property in the area ie other aircraft, cars, homes, corn fields etc.

Fourth: you may have rigging problems, trim problems, engine problems, 
propeller engine mismatch problems, gear alignment problems, cross winds, 
density altitude etc.  These things can all come together VERY RAPIDLY and 
UNDETECTABLY (until the last minute) while you are gaining speed and loosing 
runway length, in other words, running out of ideas, altitude/airspeed and 
options all at the same time because of a short narrow runway!

This is just my $.02 worth your ideas/experience level may differ!

Re: KR> Got motre training done yesterday

[Parley T Byington via KRnet]

Craig;

I noticed the same thing, I am wondering if most KR-s have this problem, I know 
mine did.  I just finished modifying mine hopefully to solve the out of center 
ball, by moving the vertical stabilizer leading edge spar slightly to the 
starboard side.  Before taking this modification on, I had installed a spring 
to the port side rudder cable and attached it to a hand crank ( I bought a 
camper window opening crank assembly ) which was mounted on the port side of 
the cockpit behind the side mounted throttle/mixture/carb heat controls.

This rudder trim worked well but I didn’t like the thoughts of my rudder 
assembly being out of trim and since I have had my bird down for other 
modifications, including attempts to take some weight off it, I thought I may 
as well do all the little mods I had been thinking about.

Other KR owners situation may be different, mine is a plans built original with 
retracts and an 1835 turbo charged VW with full electric including a geared 
starter.

Re: KR> Fixed lending gear.

[Parley T Byington via KRnet]

I changed out the 3/4 inch spring bar and installed a 1 inch spring bar on my 
kr2 after hearing about the hard landings putting the wheels up through the top 
of the wings on some other KRs with retracts.

My kr2 is actually a 1.5 bird since I made it a single seat version due to the 
gross weight being 1070# that includes me and 18.8 gallons of fuel.

Keep in mind my bird has a VW 1835 with an A-Jay turbo charger, electrical 
system, transponder and geared starter motor.

I also modified the gear lock system to use a 1/2 inch locking pin through a 
semi circle arch of steel that mounts to the center section hinge and the 
floor.  This pin is spring loaded to lock in place in the up and down position 
and is retracted via a jet ski steering cable and has an emergency hand hold to 
operate if the cable breaks.

I have not flown my bird for almost 19 years due to health problems (diabetes) 
which I am getting over having to use insulin and so should be able to pass my 
physical here shortly.  

I have been modifying several things on the plane getting it ready to fly 
again.  I am currently building an aluminum seat and I changed the position of 
the vertical stabilizer spar to eliminate the need for rudder trim, I was 
having to hold some left rudder to center the ball prior to this.  I also 
relocated the battery to the firewall, it was behind the seat before, and I 
moved the oil cooler from the top of the engine to the bottom and gave it its 
own NACA scoop for cooling air.

When I get everything back together and ready to fly I am hoping that I was 
able to lower the empty weight some and have a more forward CG for better 
control of pitch sensitivity.  I have approximately 250 hours on my bird so far 
and it is a lot of fun to fly.

I have flown it to Edwards AFB for their airshow a number of years ago and also 
to Wendover Nevada and several local airshows here in the west.

Oh, one other modification I am thinking about doing is to have the one inch 
spring bar machined down so that it tappers on the outer ends to reduce some of 
the weight without compromising the stiffness to much.

I also designed my own fuel flow gauge which uses no moving parts, it is a 
capacitive type fuel gauge and is very accurate, it uses a capacitive baffle 
plate inside the fiberglass tank and is accurate within 1/2 gallon in all 
attitudes.

Hope this information helps.

Re: KR> dashboard question

[Parley T Byington via KRnet]

My canopy is hinged on the front edge of the canopy and the fuel tank.  I used 
a piano hinge and then made my canopy frame come right down on top of the 
instrument panel.  

The canopy is supported by a gas cylinder on the right side of the fuselage.  
The canopy is simple to remove by pulling the hinge wire out and lifting off 
the canopy.

Hope it helps.

Re: KR> aileron balancing

[Parley T Byington via KRnet]

Dec.15,2017
Subject: Lead aileron castings

To whom it may concern;

I calculated the size/weight needed then made a mold using plaster paris of 
that calculation.

I heated the mold in the oven to prevent steam explosions prior to pouring the 
liquified lead into the mold.

Once the mold was heated to 450 degrees I poured the melted lead (using proper 
face shield, gloves, and full body heavy clothing to cover all exposed skin 
surfaces) into the mold and let cool.  I then shaved the lead weights using a 
sure file to get the weight to the exact amount needed to counter the aileron 
and perfectly balance it.

Be very careful when pouring molten lead into plaster molds that the mold has 
been sufficiently heated so that all water is gone or it WILL EXPODE in your 
face throwing molten lead in all directions !

Another alternative is to use heavy paper/cardboard to form a square mold to 
pour the molten lead into, the sides can be taped together using ordinary 
masking tape, several layers, without the tape burning through until the lead 
solidifies.  I have used both types of molds.

Hope this is of some help

Re: KR> 4" Prop extension for my KR2S with a Revmaster 2100D engine

[Parley T Byington via KRnet]

Date: Wednesday; Oct.25,2017
Subject: Prop extension

Luis;

I have a prop extension.  Mine measures 4.25 inches from flange face to prop 
side but I am not sure it will fit a RevMaster hub.  I understand that there 
are two different bolt patterns used on VW engines and I think that the 
Revmaster uses an SAE type 1 and mine is the other type.

Let me know which one your engine uses and maybe we can see if this one will 
work for you!

PS I won’t be able to respond until Monday, I am going out of town early 
Thursday.

Re: KR> fiber glassed fuselage

[Parley T Byington via KRnet]

Robert;

Yes, there have been a lot of Krs that have had fiberglass covered over the 
fuselage.  Mine, N54PB is one of them, I covered mine so as to aid in the 
finish paint as well as to seal and protect the wood.  Yes, it does add some 
weight but my plane flies just fine and I made it into a KR2 SINGLE place to 
keep the gross weight down.

Hope this gives you some ideas and confidence in the Kr.  

Two things that I will mention here in case anyone is building the KR with the 
original retract system; 

1.  the planes call for AN 3 bolts to be used to attach the gear legs to the 
spring bar…DO NOT use AN 3 bolts, they are TO SMALL, use AN 5 in their place.  

2. The original gear locks are a accident waiting to happen, redesign those 
locks with a positive shear bolt arrangement to ensure their locking and not 
coming unlocked during landing. 

3. Most krs are heavier than the plans call for, it is hard to go anywhere 
legally with out radios and electrical systems, I suggest installing a heavier 
landing gear spring bar if your weight is normally above the published gross 
weight of 900#. 

Don’t ask me how I know the importance of these two flaws in the original Rand 
Robinson design.

The Kr is a very docile tail dragger on the ground, the original design is very 
pitch sensitive in the air, I lengthened the stick to help prevent PIO, pilot 
induced oscillations.  My suggestions for improving the original design is to 
lengthen the fuselage by 18” to 24”, increase the area of the ailerons and keep 
it as light as possible.

I had a total of 1 hour of logged tail dragger time when I flew my bird the 
first time.  I had many other hours in various tail draggers as a co-pilot 
passenger but not much time in actual landings.  The Kr with its wide landing 
gear is very easy to taxi and has very little tendency to ground loop.

I have over 4000 hours of jet simulator, the real ones, and was very glad that 
most of those simulator hours were in F4-D and E models when I first flew 
N54PB, I also had a large dry lake to fly off from for the first test flight.  
The F4 simulator and aircraft are quit pitch sensitive also and my experience 
in them helped me quickly overcome the tendency to over control on the first 
and latter flights of my KR-2.

Re: KR> Melting lead

[Parley T Byington via KRnet]

Date: Saturday, Jan.28,2017
Subject: Melting lead and safety precautions

When making my counter weights, I built some molds out of plaster of Paris to 
shape  then used the female mold to pour melted lead into.  

ONE VERY IMPORTANT POINT HERE; that is heat the mold (plaster) in the oven to a 
high temperature to ensure there is NO water left in the plaster PRIOR to 
pouring molten lead in it.  FAILURE to do this will result in an explosion of 
molten lead that will cover everything with in a 10 ft radius INCLUDING the 
person pouring the lead!  ALWAYS WEAR PROTECTIVE CLOTHING, GLOVES, EYE, FACE, 
ARM, AND BODY PROTECTION.

Molds can also be made from cardboard and masking tape, yes some of the tape 
and cardboard will burn but will not leak before the lead solidifies and is 
easily removed.
