KR> turtledeck

2008-10-12 Thread larry severson
In the last year, 2 Q2s ( 1 dragger + 1 tri) have ended up on their 
backs. Both pilots walked away because of a bulkhead behind the seat 
and tight seat belts saved their heads from brain scrambling. (One 
pilot - tall- had a slight head scratch, the other none other than 
anxiety.) Not too many KRs that I have seen have enough bulkheading 
at this point to provide adequate protecting. Just a suggestion.

Actually, the plans boat side are laid out flat, but bent when built 
up. Maybe I have not looked closely enough to get the actual firewall 
to tail of the KR2S, but the plane is appropriately shorter that the 
side plans. May be it is a 2, maybe a 2S. In any case, in the early 
days, builders were increasing the size before the KR2S plans came 
out. The project has been indoors all of its life, so the wood is in 
good shape.

As the professor at the school rated #1 in the US for composite

material of better. If you start with polyester, you can repair with 
either polyester OR epoxy. If you start with epoxy, you HAVE TO use

google flaps. There is a lot of info available to answer your 
questions. Short answer, small reduction in stalling speed, but 
effective as a speed brake (drag inducer).

one reference included:
In 1920, Orville Wright and J. M. H. Jacobs invented the split flap, 
which consisted of a hinged section on the trailing edge of the 
underside of the wing. The split flap was simple and also had the 
benefit of increasing drag, which helped a pilot descend toward the 
runway at a steeper rate than current wings would allow and thus made 
landing approaches easier.

polyester shrinks about 5% over time, and it is not as strong, nor as

No. The FAA has a very specific checklist of items evaluated in 
generating the 51%. Time used does not figure in the calculation, 
only % of checklist items done by the builder vs the manufacturer of 
the kit. It is possible to buy a flying plane, modify it heavily, 
treat the unchanged items as kit supplied, decertify the plane, 
re-register it, get a new airworthiness cert, and get the repairman's 
cert - as long as the new work amounts to 51%, per the checklist.

I did not list the specific numbers because some planes will not have 
119 operations according to the list (Q2/Q200). Also, an autogyro may 
have more than 119 operations. You check off all operations completed 
prior to your activity as being done by the kit manufacturer, and all

Understood, but I have the additional advantage of having an engine 
with too high oil pressure. It is almost unbelievable how far the oil 
was thrown out of the tail pipe due to the high speed it exited. The 
pipes centered on the ducts was guaranteed to concentrate the high 
temp under the fuselage at the exit point. This all goes to the fact 
that this is all a complex subject and sometimes what seems like a

I have a Sport Aviation article that says standard baffling has a 55%

As far as mating the plenum to the plenum goes, try scat tubing. It

The Q2 has a laminar flow wing (smooth flow, minimum drag), One 
person decided to put a trim color on the leading edge. Plane didn't 
want to fly due to the SLIGHT disruption of air flow. After he sanded 
off the extra paint and restored the surface, plane flew great.

Carbon fiber if 3-4 times stronger than Eglass. However, the wing 
construction of the KR2 does not call for 3+ layers of Eglass, so you 
will only add cost.
Alternatively, you could consider using the construction methods in 
"Advanced Composite Techniques" by Zeke Smith. I hope to build a wing 
panel using that method sometime in the next year for test purposes. 
I expect it to be both lighter and stronder.

AeroPoxy, using the 2 hr cure hardener, will give you a basic 205 
degree de-link temperature when cured at 77F (128F rise over cure 
temp). After the cure time of 24 hours, post cure can be done, but 
waiting 2 weeks is better. Raising the temperature on the unstressed 
(not on the aircraft) structure to 140F for 3 hours should raise the 
de-link temp to 240F+. With a white paint job, you should be safe 
under all Phoenix conditions. One inexpensive method of raising the 
temp on a wing panel is to create a heat box using thick alum covered 
insulation blocks, heat lamps, and a fan to circulate the air inside 
the "oven". A temp indicator to control conditions is necessary.

All standard texts recommend heat post cures. Epoxy does get stronger

The real question is what is used to join/attach the skins. Vinyl

In the US, by definition, ALL homebuilts are experimental.
If it was not produced on a certified production line, it is experimental.
When you built it, you were experimenting; therefore, the plane is an

No one gives out such a document. The FAA will only certify it as experimental.

They also shrink with age.

Alternatively, many epoxies can be post cured. PTM (maker of 
aeropoxy) has epoxies that can be post cured to have de-linking 
delayed past 325F, but do you really want to have a wing skin sitting 
on the ramp at over 170F?

The 14mm (old head) used an aircraft magneto spark plug. (The old 
head also required valve work after 150 hours).
The new heads take inexpensive 12mm auto plugs, add 5 HP, and no 
longer have the valve problem. However, they require an adapter kit 
to modify the mag plug wires, or the use of an auto ignition system.

Optimum temperature for epoxy application is 77 degree F. Air 
temperature can be lower if the epoxy is heated. Higher temperatures 
will reduce the working time. Lower temperatures will increase it. 
There is a temperature (each epoxy is different) below which the 
epoxy will not cure. Few epoxies will cure if the air + resin are at 
13C. Heating the resin helps. Keeping a heat lamp on the part being 
joined will solve any problems.

They all have a de-linking temperature.

Aeropoxy has among the highest de-link temperatures:
180F for 30 min hardner
190F for 1hr hardner
205 for 2 hr hardner
when cured at 77F epoxy temp. These temp capabilities don't appear 
for several weeks after cure date.

The de-linking temp can be raised with post curing at higher temps than 77F.

There are tables for temp increase with various color paints. Without

I have a turbo 2100D. Due to problems not related to the engine. I

fantastic. Also, they are the only VW derivative engine manufacturer

to start it first. I have since had it to 3000+ RPM several times 
with nary a hiccup. Oil consumption is LOW and the engine runs 
smooth. The engine (built for the original owner in 1983) now has 12.9 hours.

What is currently preventing first flight is getting the engine 
monitoring system operating properly.

Adding wing span will reduce the stall speed. Reducing HP and 
increasing drag will reduce cruise speed. However, remember the short 
coupling problem when increasing the wing span. I highly suggest a 
longer fuselage than even the KR2S. Then you can call it a NKR2SS, 
not a KR2S, but super stretched. Now it is your design.

The big problem is that there are too many who need to "burn rubber" 
because they can. Rapid throttle advancement will ultimately shorten 
the life of any engine. When I was an airline pilot, we added power 
slowly as a general practice. The max temp reached during takeoff as 
a result was 10 degree C lower and the engine life was doubled. The 
turbo is tempting, but it is not necessary to stress the engine.

If the customer did not abrade the attach area, that would be the 
effect. However,

(I queried an expert)
I understood that epoxy would be an effective join for vinyl ester, 
but not the other way. True?

(response from an expert)
Larry , if the part is made of VE and you join or bond it with an 
epoxy joint compound np. because of the more aggressive covalent bond 
and lap shear of the epoxy. Vinylester as a joining compound has a 
much lower youg's modulus and subsequent lapshear so that is correct.

What he is saying is that one should always go equal of better in

We are analog. We see angular differences, even out of the corner of 
our eyes. Digital (and tape) displays need to be read which requires 
looking directly at the gage. Also, there is the problem of 
resolution of the digital display. Human Factors studies validate the 
fact that until the screen reaches the resolution of the printed 
page, speed of reading, accuracy of data acquisition, and retention 
of data goes down directly with the drop of resolution. With an 
analog gage (needle rotating around a circular display), the 
resolution of the screen has little impact.

Anyone in the LA basin who is building, or thinking of building, a KR2 - or

you need for building available at no charge. I am currently taking 2 
classes and a lab course for a total cost under $175. Yesterday, vacuum 
bagged a carbon fiber speed brake for my Q2. Next, I plan to make up a KR

My Revmaster uses J wires held in the head with allen screws. These tend to

I need to talk to EAA about the registration problems. I can't do that 
until Tuesday. I will let you know.
I have no problem getting to Boston by commercial air. I will have to 
research the further legs to your area.

KR> Canadian KR2

2008-10-12 Thread larry severson
Jim:
I talked to the EAA today. To get it US certificated requires all of the 
homebuilder documentation like a newly built plane plus about 2 months 
downtime (Canadian decertification, and then US cert & registration - 
during that time the plane can not be flown).
I was interested in the possibility of getting in the air immediately. 
Since that is not possible, I am going to pass on this opportunity. 
However, I do suggest that you get all of the documentation together with 
some pictures of its current condition for the next person.

I will have to make the final repairs on my Q2 so that I can fly while I go 
back to finishing my KR (it requires major reworking).

There is a program called Kitlog. It helps you track all of the building 
progress, as required, and then fills out the required paperwork giving you 
the complete requried submittal package. I received a trial package through

>I need to get the Revmaster started and get it all lubed up again.  Is there
>anything special I need to do to the turbo since the engine has not run in
>months?

I bought a plane that had sat for 3 years with a turbo Revmaster. I ended 
up having to clean the points on the mags, add oil, and start it. It ran 
immediately, and beautifully; however, it threw a bunch of oil out the 
exhaust until I ran it up and got the engine fully warmed up a couple times.

>I was going to change the oil in the engine and see if I can get my

>way I can accidently overboost this engine.

Wrong! The turbo is controlled with the throttle. Put on a big enough prop 
(I have a 54X54 which gives me just over 3000 static) or watch both the RPM 
and manifold pressure. Take off power should net 3200 RPM and 32-34 inches 
of pressure. In an emergency, you can go to 40 inches, but at the cost of 
engine life.

Another thing to look at is the type of spark plugs. If they are aircraft, 
the heads normally have about 150 hours life. If they are auto, you have 
the new heads which add 5 HP and are basically life time. I will be putting 
on the new heads when I get near the 150 hour point. The new heads cost 3X 
the price of the old ones, but cheap at the price.

Turbo (old heads) 75HP, new heads (80HP)
No turbo 65-70HP

Turbo version puts out more power than the O200 at 8000 ft.

Sorry, but in both my classes in Aero in college, and during my training as 
an airline pilot, ground effect starts at 1/2 the wing span. (Drag due to 
lift reduces by 1/2 at the 1/2 wing span height because the down flow off 
the aft part of the wing is cut off.)

That is why much of the early part of the flight of the Voyager around the 
world flight was down next to the water. However, the 1/2 figure is where 
pilots first notice the effect.

When carrying a passenger:
1. no problem changing control.
2. easy to ride controls when training passenger.
3. can put engine controls in center making it possible for either pilot to 
control.
4. Emergencies (medical) happen. Do you want your passenger to die with

I replaced mine. Yes, I had to remove the panel, and yes it was a pain, but
