KR> Max RPM

[Travis Berry]

i have the same problem with my it also when it idles for a while it seams to 
over lode the plug when you increase the power i'm not sure what the problem is 
i call them at revmasters and he said he thought the plan was over pitched i 
then called the prop inc and he said he could repitched it but he would try it 
out flying first because he said he has not had that as a problem so that what 
im going to do before i have it re piched if you find a solution please share 
it

Welcome to the club.  I sincerely wish you persevere and can enjoy the 
experience, as well as the flight time, that I have over the years.  It's 
become my life's work, which then evolved into a great circle of like-minded 
friends

KR> Well Here Go's

[Gary Robison]

I hate to clutter up the KRnet with this but I just have
to announce it.

I retired this year on May 1st

I have under construction a 24 X 40 heated/air conditioned 
"MANCAVE" to be completed in time for the gathering.

Today I called and gave up my credit card number for a pile
of spruce and plywood. 

Eight years I have be looking at the KR

Four years ago I bought the plans.

Two years ago I collected 3 Corvair engines.

Let the gluing and sanding begin.

KR> Fuel Situation Update

[Dave Dunwoodie]

Thank You to all that replied and offered suggestions and thoughts.  I 
really appreciate all of the ideas, and they helped me get focused.

The engine is a Revmaster 2100-D-75.
The prop is a Warp Drive 3-blade, non-tapered, 52".

I performed fuel flow tests this morning and arrived at 21.8 GPH 
free-flow rate.

In checking total travel of the mixture lever, I discovered that it was 
rotating only (roughly) 60 degrees, not the 90-95 degrees per 
Revmaster's requirements.  Given this discovery, further checks were halted.

I'm now in the process of locating or fabricating a lever with 3 holes, 
total length about 3.5" which can be used to translate 1.5" of cable 
travel into 2.5".

Thanks to all for their help!

Dave.

KR> Gathering pre-registration

[Larry Flesner]

It looks like the problem with Gathering pre-registration has been 
resolved.  If your name is not on the list now, please 
re-register.  If you register multiple times, your last registration 
is the only one that will be listed.

Thanks.

KR> Re: KR2S Plans lacking detail

[Tim Caughron]

Ok I get it. Thanks guys for all the replies. Makes me feel better thinking
I have the full set of plans and knowing there are completed and flying
planes made from them. I will not be deterred - just makes it more of a
challenge; I love that anyway. The only thing it is going to do is slow down
my modeling, but that is fine.

Thanks again to all.

You're not the first guy to wonder these things, and you won't be the last. 
A lot of these planes have been built and flown, despite the poor state of
the plans.  Those plans is the reason I built my website, the first one 
devoted to KR construction.   If you look hard enough in the plans notebook 
for the KR2, you'll find mention of joining the fuselage sides up to the
vertical stabilizer's aft spar to finish forming the boat.  This is the
width of the fuselage back at the place where the rudder fastens (it's a
tapered piece that's something like 2" wide on average).  Taper the spar
first, and leave the plywood overlapping a bit to provide a gap seal for the
rudder.  So use the farthest aft measurement that's given for a cross member
as your last known point, and then the tailpiece, and the other cross pieces
are just cut to fit.  I'd give better directions, but I'm at work and the
plans are at home.

As for tri-gear, that fits under the same heading as a lot of things...you
don't get the one-sheet plans for it unless you bought the optional parts
themselves from Rand Robinson.  Diehl sold most of the nose gear, and his
instructions are online at
http://www.diehlaero.com/NOSE%20GEAR%20INSTRUCTIONS.pdf .  I think Steve
?Glover at NVAero is now selling that gear.  I'll let him clarify.

There's a lot of guesswork building a KR from those plans, so better get
used to it now...

KR> static rpm

[STEVE bennett]

If your pulling 28 something MP at WOT, one would suspect that the prop is 
limiting the engine from turning a higher rpm.  

On another subject, typically Warp Drive props and the VW engine have not made 
for a great long term marriage.
