KR> fuselage length

[n357cj]

Hey guys,
After thinking a little bit more I see that this can still be real confusing to 
anyone reading any of this in the future. Here is what I propose
Anyone that can (flying plane or not) take a measurement from the front side of 
the main spar to the back side of the fire wall plywood and take a second 
measurement from the front side of the main spar to the point that the tape 
measure touches at the tail-post intersection at the rear floor position of the 
fuselage. Basically a center-line of the plane profile. This will give a full 
length as well as a break down foreword and aft of the main spar for multiple 
planes. It is also a location that should be accessible for almost every KR 
built.
 I guess it would help if with the dimensions I could know if it is a KR2, KR2 
modified, KR2S, KR2S modified
?E-mail them to me privately at n357cj at ptd.net and I will make a chart up 
showing all the dimensions relative to each other and assign them to a N number 
for future references. Pretty sure Mark L. would link it to KR net for us.
?? ?The end result of this exercise I would hope to have real factual 
dimensions instead of the subjective add this to that or the other and it flies 
great. I also am still believing that we are all pretty close together with 
only a few out-layers in the statistics.
  I'll do both of mine tonight
Thanks for the help.

KR> Fuselage Length

[Allen Wiesner]

For David Swanson and for general info:

  Note that the following is for my fuselage only, AND it is still under 
construction.

  1.  The longerons I got from Wicks during the '05 Fly-In (anyone remember the 
PVC sewer pipe tied to the roof of my mini-van?) measured 168 1/2" or 14" 1/2".

  2.  I am trying to make my "boat" without the "banana" so the following 
dimensions apply only to my fuselage.
  A.  I first built the top frame flat on the table with the longerons bent to 
a fair curve, glued the doublers to them, then added all the upper 
lateral/diagonal stringers & gussets.  The dimensions are: 162" from the front 
edge of the firewall to the afl edge of the tail post (tail post = fin aft 
spar) & 40" wide at the firewall going to 46" wide at "H*, (shoulders / seat 
back) (6" behind "H", wing aft spar) and then narrowing to the tail post.  The 
longitudinal spacing is: "A" (firewall) to "B", 8", "B" to "C", 9", & "C" to 
"D" (wing front spar), 10", for a total of 27"; and a total of 6 - 14" bays and 
one 13" bay from "H" (rear wing spar) to the stabilizer forward spar with 
another 12" to the tail post.  That took 13'  9" total of the longerons, but 1" 
of that is left forward of the firewall and glued to a temporary stringer to 
hold things together until I can add the upper firewall supports.
  B.  I then made some simple jigs to hold the lower firewall 
support/compression brace/lower longerons in place above the table/upper frame 
and added all the lower lateral stringers.  The dimensions are: 18" deep (high) 
at the firewall, going to 24" deep at "D", and then back down to 12" at the 
tail post (with the 7 degree tilt of the tail post, that makes it 160 53/64" 
long) & from 16" wide at the firewall to 40" wide at "H", then in to the tail 
post.  That also took 13' 8" of the longeron material; so in my case, the 
downward curve of the bottom longerons makes up for the leeser outward curve.

  I am now in the process of adding all the vertical/diagonal stringers to 
connect the upper & lower frames and plan to add the bottom skin next.  I'll 
then free the frame from the jigs, turn it right side up, and add the upper 
engine supports/structure and the side skins.  Hoped for result: straight and 
flat upper longerons and a firewall at 90 degrees to the run of the upper 
frame.  Fron the above dimensions, you can see why I call her "The Fat Lady"

KR> Fuselage length

[RANDY POWELL]

Having read through the archives researching the fuselage length for a KR2S it 
would seem that the consensus is to add two inches in front of the front spar 
and 14 inches behind the rear spar.  Is this still the generally agreed way to 
go?.   Also if lengthening the fuselage in this fashion is the trend to go with 
the new wider elevator and new airfoil or stick to the stock elevator width and 
use the new foil ?.

What you are describing is the difference in the KR2 and the KR2S.  Adding
another bay to the tail will get you another 14", and the only guy I know
that is flying one similar to that is Larry Flesner, and his is still not as
long as what you are talking about (24" more than the KR2 plans, if I
remember correctly).  Others are building that way though, so there should
be data points in the future. The KR2S is really long enough like it is, but
there's probably nothing wrong  with adding another bay other than it will
lower your fuselage angle on the gear, increase your wetted area, and weigh
a little more.  Larry has taller gear, so he's compensated for the 3 point
attitude of the fuselage and then some.

I would be careful about adding 2 more inches in front of the main spar,
especially if you are planning on using a heavy engine like a Corvair or
O-200, because that will move your engine out 2" farther also, and you may
need to add weight to your tail.  I'm a light pilot with lead in my tail
already (in the form of a battery and elevator counterweight) and my engine
is within 3/8" of the firewall, and my CG is close to the forward limit with
me flying it.  If I added 2" to the engine mount, I'd certainly be looking
at some more lead in the tail.  So consider your leg length before you just
go ahead and do that.  Ed Blocher added 4" to his, and he was a short guy
with a Corvair engine!  Just don't make that mistake, unless you're a heavy
pilot and plan to use wing tanks with no header tank (which is also what I
have).

As for longer horizontal stabilizer, I can't testify as to whether the extra
foot of length (6" on each end) makes much of a difference, but I can tell
you that it works fine that way.

[Joseph H. Horton]

Randy,
I am not sure that it is a consensus do that to the 2S plans. It
seems that is a wording that is being carried through from a time when
the first KR2 was stretched until the 2S plans came out with the
additional bay added. Then if I am not mistaken Mark Jones is the first
one that I can think of that addled more space to the fuselage simply to
fit his natural born airframe. Randy, your about my size and you are only
going to add time, labor, and anxiety to the project. I'll be down and
give you that ride. Then you can judge for yourself. 
As for the tail feathers- you could go ahead and do the airfoil
shapes. making it larger does not seem to matter to me. That may be what
you might be comfortable with. I have flown with Bill Clapp and Mr.
Langford with airfoil stabilizers and don't see any real difference from
mine with stock tail feathers. I think the difference comes with the
incidence that the stabilizer is set to.

Hi Randy,
   If you're making decisions based on the note I wrote, you might want to
listen to what these guys are saying. I'm just throwing ideas out there,
trying to get information. Changing the length significantly has its
ramifications; one being the plane may be very difficult to balance if not
impossible. Whatever I decide to do, I take on the responsibility of, it
might not work. I'm just gambling on leg room because I have to. I've grown
up with clothes that don't fit, cars that don't fit, and now planes that
don't fit. Being tall has it's short commings. I'll probably go with the 2",
but it might not work. I'm still trying to decide on what to do with the
back of the fuselage.

Hey Randy,

   Your wanting leg room and everything as far as comfort have you 
checked out Donald Reid's KR-2XL?   Don Reid's KR-2XL I was looking at that for

This question is primarily to Mark but anyone please chime in.  I am just 
getting started on my 2S and am planning on lengthening the fuselage by 14 
inches by adding one bay aft. My question is, i am 5ft 11in., should I add 
anything forward of the front spar for leg room?

 I flew to MDQ yesterday to drop off a friends daughter and I don't think gusty

Hey John,

  I am 5' 8" with a 29" inseam. I built my plane with the standard KR2S 
dimensions up front and stretched the rear 22" by adding two more bays. I think 
it ended up being 13' 9" from firewall to tailpost.

  I have to tell you I was very disappointed after I made my composite seat 
that I am WAy short of the rudder peddles. I have to make my seat 
adjustable just so I can reach them.

  If you make the composite seat like I, and others have done (search the net) 
with the bottom of the seat near the floor, you will have NO problem with leg 
room.

  My plane will have 3 seat adjustments on both sides, and should accomodate a 
person my size, all the way up to 6' 3".

John, 
be cautious, I added 28" behind the rear spar (2 bays) and even with the 
O-235(208 lbs + accessories)  up front I am concerned about ending up with a 
slightly tail heavy condition. (my tanks are also in the stub wings between the 
spars) which adds to the rearward cg . the longer moment arm makes a little 
extra weight a problem.   just my 2 cents
