KR> Prop

[John Martindale]

I replaced mine with a 3 blade flight adjustable Bolly turning the other
direction when I went to a psru gearbox. I still have my Warpdrive in case I
go back to direct drive with 5th bearing.

I was wondering if anybody is still using a 3 blade warp drive
prop with a corvair engine? Possibly John Martindale? I have
a 58" with factory modified tips that I might try to sale in favor
of a fixed pitch wooden prop for weight. I will be installing one
of the 5th bearing setups that are available with a factory nitrided

Thanks for all the great info.

KR> Fuel tank pick up and vent

[Steven Bedford]

Thank you for the information,

It is a 32mm aerocarb, 12 gallon RR fuel tank, stock cid corvair, and the 
vent is a 5/16" aluminum tube
under the fuselage about an inch bent into the air stream.

Welcome Barrett

In reading your introduction I thought I was reading something I wrote.  Your 
situation is very similar to mine and a few others here.  You'll find this list 
and the Corvair list very helpful and ...well I  don't want to spoil it for 
you.  Good Luck and I hope you and I both are in the 10% that finish their 
projects.

KR> Diehl Wing skins

[Mac McConnell-Wood]

Hi Russ,
 I used Dan's skins on my KR2 some years ago and was fortunate in having
met Dan at a gathering. I think I was the first to use them in the UK ,and
had no problems except that the rib cut out markings didn't correspond
somehow .
 I contacted Dan and he reassured me that my markings were not
accurate ( it was in the '90's and I've forgotten how exactly-but I'll look
up my notes if you can't get better advice).
 One thing I do remember is how fast vinylester goes off , so you have to
get a reliable pal and rehearse the procedure.
  I also had to open inspection panels in the lower skins to satisfy our
inspection authorities who would reinvent the wheel if it hadn't been made
in Birmingham!

Cheers,   Mac  ex  KR2 G-BVZJ

Yes I am doing my RAF48 wings using the Diehl skins this winter.  I am in NW

Fw: KR> Fuel tank pick up and vent

[joe.kr2s.buil...@juno.com]

Hey guys,Let me see if I convey this with some sort of reasoning. First 
history: I started out with aerocarb set up with a fuel pump and a regulator 
and ram air on a corvair. The fuel tank is vented from the very very top of the 
tank and sloped down hill behind the panel and out the side of the fuselage 
just in front of the wing about 7" up from the top of the wing on the passenger 
side. It is comprised of a 1/4" alum tube inside the tank and to the outside of 
the tank, the vent is then 1/4 " clear tubing to the side of the fuselage and 
then changes back to 1/4" alum. tube. The tube through the side is bent in  
somewhat of an crooked S shape so that it points straight into the slip stream 
of the fuselage. The open end faceing front is flared with the flaring tool 
that would normally  be used to install the flared fittings for a AN-4 flared 
fitting. The fuel pump was removed in favor of gravity feed during first ground 
runs. The ram air was removed as problems showed up during taxi testing. The 
slight ram pressure that the vent tube picks up remains after 6 years and 660 
hours. There is a fuel pressure sensor installed low in the system that reads 
to the tenth's of a pound. It never, even with as low as 2 gallons of fuel 
remaining, reads less than .9# at static. And around 1.4# in flight. I since 
added the fuel flow and installed it upstream of the pressure sensor. The 
pressures dropped but not to what i had calculated them to be. The static with 
low fuel is never below .8# and in flight now operates at 1.2# . The head 
height for pressure is 19" sitting level and certainly less in any climb. I do 
not have any back flow preventer installed and my opinion is something 
mechanical in a line that small is something that will get stuck. I got lucky 
and the pressures are centered around the published required pressures for the 
Aerocarb.Steven, I don't remember you saying what engine or what size carb, or 
header tank. The Aerocarb does work and I can not explain some of the problems 
that people have. Given that statement if i had more money 10 years ago I would 
have installed a ellison. My experinces with auto fuel and the Aerocarb are not 
good either.Joe HortonCoopersburg, Pa.-- Forwarded Message --

I've had no experience with Aerocarbs. I suspect it might given they are
reputedly a calibrated "fuel leak" but I don't know. Guess it depends on the
diameter of the vent and thus the amount of pressurisation. Someone else
might chime in or you should contact the manufacturer for the definitive
opinion. A simple vent in a cap will leak if upside in a prang. Use an
aircraft designed one. I think these have some kind of a rubber flap
arrangement that prevents this. Check out Aircraft Spruce.

John

I will be running a areocarb on a corvair engine and was wondering
if running ram pressure into the vent of the header tank will cause a
problem with this carb.  Should I be using just a vented cap instead.

 Is there anyone that is getting ready to do Diehl wing skins on thier KR?
I have a stock KR and will be attempting to do the wing skins soon. I have 
already modified the spar to the 4-15/16" at the outboard end. I purchased the 
skins and ribs from a builder a lot of years ago and the ribs were already cut 
from the sheet.
However how do i verify that the ribs are correct and as accurate as they need 
to be? What is the spacing for the ribs?  and i need some information on the

KR> As I sit over here in AFG...

[Dave_A]

The 'what to do with the plane when I get home' project list keeps going 
through my head.

I'm back to tri-gear-conversion with reversed stock mains as the 'first 
try' to make my plane a nose-dragger. The new plan (based on what I've 
read from here, better pictures of my plane, and a set of KR-1 (yes, 
1... But the design is similar enough, IIRC, when it comes to the stock 
gear, for this to work) plans.

I'm looking at using 2" blocks of wood as spacers to move the stick aft 
from it's 'stock' attachment point, creating an area behind the stick 
for the spring-bar, and bolting the gear into the 'down' position using 
brackets in place of the latch arms. Since the stock gear is bolted 
together, no cutting of exterior skin should be required (originally I 
was expecting to have to slice an access panel to get the gear out)... 
I'll have to re-route the aileron cable a bit, but I'd have to do that 
for Diehl gear anyway.  I'll also have to re-route the brake lines 
(hydraulic heel brakes) and reverse the existing foam fairings to reduce 
the 'giant speed-brake' problem.

If this works, I saved $1k, for the price of a little less elbow room 
(possibly addressable by bending of the control-stick tube into an 'S' 
shape, to move the handle back forward), and the plane will have a much 
more nose-high attitude while on the ground, than it would with the 
Diehl mains (the important part - prop-to-ground clearance, being 
determined by the nosewheel strut length, which will be the same for 
both configs)  I'll also be able to do this with far less tools 
(important since I don't live in FL, and will be working out of a U-haul 
storage room)

If it doesn't, I'll be out some time, and will buy the Diehl mains.

I'm still using the Diehl nose wheel, for ease-of-install reasons over 
other options (such as fabing my own or trying to adapt one salvaged 
from a certified bird)

With the gear flipped and the controls re-adjusted (moving the stick 
back will put some slack in the cables), I'll just have to install my 
e-bay scavenged EFIS and radios, change out the carbeurator (it's got a 
POSA now, I got an Ellison EFS2 off E-bay ($200, no less), and I see 
this as the other major 'issue' besides tail-dragger config), and touch 
up some paint...

I've also been told to replace the points on the mag...

'Go time' for this project is the 2nd week of my mid-tour leave, in 
about a month. Nothing to get in the way, at all...

P.S. One question: How much space is there typically between the back of 
the panel and the fuel tank (Assuming the plane was built to plans, 
without mods)

Hi Dene!

Thanks!

I am hoping to do a "Round SA" trip first week in January 2012 so yes, I 
will be in PE soon if my plans work out, will let you know as planning 
progresses. The current engine setup in VYZ was developed over a period 
of time with many mods along the way and still a few I want to do but 
mostly small things now.

My seats are molded (FG/Carbon) and are quite deep, that helps a lot if 
you are tall like me, at 6'3" my head is far from the canopy. I am going 
to have the seats recovered soon, I do not have any decent photos of 
them but I will make a point of taking some!

Good luck with your project and keep us informed!
Regards,
Rudi
