KR> AS504x wing skins

2015-01-14 Thread Chris Prata
I just finished reading the airfoil section you cited. Thank you, very helpful. 
And great to know that such collaborative development has taken place, with 
great results. Exactly what the Experimental Certification was designed for.

My first flight of the year,  1/11/2015 

with  my oldest 12 year old son, Juan Eduardo, we flew to San Nicolas, Buenos 
Aires landing and come back to San Pedro, the flight was 50 minutes on very hot 
day, 95? f  out and 101? f into the cockpit 
San Pedro landing was at 1470 feet over the soft runway (grass), in San Nicolas 
was at 990 feet with a density altitude of 2170 feet.
the climb was very soft to keep oil temperature below 248? f, the cruiser to 
1500 feet was comfortable if we forget the heat.

I like making things myself.  The KR airplane is so simple that I  don't 
think you need any parts that are prefab.  I certainly wouldn't buy  the skins 
as the new KR airfoil would be faster anyway.  Landing  gear is easy to 
make.  Wheels and brakes...maybe Tracy Obrien or find  someone who has some to 
sell. Canopy can be made yourself or a canopy from  something else cut to 
fit or even made by a custom canopy builder.  Wing  attach fittings.I have 
drill press.  I am sure Ken Rand never had  someone build these parts for 
the prototype.  Control sticksuper easy  parts to make.  The beauty of a

It is great that the wing skins, landing gear/wheels/brakes, canopy,  wing

What about the control  surface hardware and rigging? I'm guessing whats

In fact, if we  didnt have nvaero, I wonder if the entire plane could be

KR> AS504x wing skins

2015-01-14 Thread Mark Langford
And I should mention that Steve Glover at nvAero has spent a lot of time 
and money making a set of molds to build wingskins for the new airfoil, 
so thanks to him, you can now buy a set of skins if you don't want to 
build them.  They are primarily for the 2S, I think, another reason to 
start with a 2S and skinny it down to KR1 width (or wider).

I said earlier it would need more rudder than the KR1 plans, but meant 
to say "vertical stab and rudder", not just rudder.

See http://www.krnet.org/as504x/ for details on the new airfoil, 
complete with free template download.  This will work fine on a KR1 
also.  There's a lot of other great info to get you started at

KR> Flaps versus belly board versus spoilers

H, is there room betyween the prop disc, and the ailerons, on a KR1? I also 
wonder what a split condition would do, could the ailerons overcome that?
As to the jets using them after touchdown, apparently they also use them in 
flight. I found a youtube video of that, passenger was filing the wing, and the 
spoilers came up at the back of the wing. The plane was rumbling a bit. Must 
have been to slow down?  
Also, the B52 Bomber "America's diplomat in the skies" uses spoilers instead of 
ailerons, IIRC.

KR> NVAero KR1 fuselage kit?

2015-01-14 Thread Chris Prata
I looked over the very nice nvaero site. It appears that there is not a 
fuselage wood or fiberglass kit for the KR1. (not popular?) so I guess that 
means plans build.
It is great that the wing skins, landing gear/wheels/brakes, canopy, wing 
attach fittings, control stick, are avail.
What about the control surface hardware and rigging? I'm guessing whats not 
compatible (if anything) from the KR2 would be off the shelf at aircraft spruce.
In fact, if we didnt have nvaero, I wonder if the entire plane could be plans 
built? (would have to solve the canopy problem, and fabricate landing gear).
Also, one wonders WHY do the plans "may have extended lead times" 
nvaero is GREAT to have though   :)   


KR> Flaps versus belly board versus spoilers

2015-01-14 Thread Ronald Wright
HI Larry,

Not sure what you mean by "the KR is not a design that call for spoilers"?  
They definitely kill LIFT which takes care of the "floating problem" of the 
KR..  They would work on any airplane when placed in the proper location.

I've got several Moni motorgliders which utilize them and they will float like 
a KR if you don't use them.  Originally a set of doors were installed on both 
sides of the main wheel pant, but the most it did was cause a nose down pitch 
attitude.  Spoilers were the solution.

If you're using spoilers, you don't have to "point the nose down to dirty up 
the air flow"..  They will stop the wing from "flying" very effectively.  In a 
lot of cases you actually have to keep power in to cut down on the descent rate 
to keep the plane flying.

I know there are other homebuilt designs using spoilers.  One type raises up 
out of the wing like a pair of scissors.  The ones on my airplanes deploy like 
a belly board except they are on top of the wing.  You don't need very big ones 
to kill the lift.  Normally installed outside the prop diameter in the root 
portion of the wing for best lift killing..

All these designs work well.  You just need to figure out which one you want to 
use, how easy they are to build/install and enjoy!

Just my .02.

Ron

 Spoilers are used primarily on gliders to kill excess lift
 in order 
 to steepen the approach to landing and also on large
 commercial 
 aircraft to kill lift after touchdown to transfer the weight
 to the 
 landing gear.? The KR is not a design that call for
 spoilers.? The 
 only shortfall, if you can consider it a shortfall, is the
 need for 
 deployable drag in the landing approach.? It is a very
 slick design 
 that makes speed control in landing? a bit
 tricky.? It will also 
 float after the flare if too much speed is carried on the
 approach.

 Effective flaps or a speed brake are both proven solutions
 to speed 
 control on landings.? The speed brake is probably the
 simplest to 
 build but effective flaps may offer other benefits beyond
 simply 
 adding drag.? If you're building to fly, go with what's
 proven.? If 
 you want to experiment and try new things, go for
 it.

KR> First flight of the year

2015-01-14 Thread Eduardo Barros
My first flight of the year,  1/11/2015 

with  my oldest 12 year old son, Juan Eduardo, we flew to San Nicolas, Buenos 
Aires landing and come back to San Pedro, the flight was 50 minutes on very hot 
day, 95? f  out and 101? f into the cockpit 
San Pedro landing was at 1470 feet over the soft runway (grass), in San Nicolas 
was at 990 feet with a density altitude of 2170 feet.
the climb was very soft to keep oil temperature below 248? f, the cruiser to 
1500 feet was comfortable if we forget the heat.

you can see a video of flight here: https://www.youtube.com/watch?v=bv8x8p5JXg0

KR> Jabiru 2200 - KR1

I would highly recommend that you extend the tail on the KR1 to improve
stability and reduce pitch sensitivity, especially if adding more wing area
like Diehl skins.  One more bay would help, but I'd go for two, along with
more rudder and horizontal stab.  A larger rudder will improve spin recovery
also.  Might as well start with KR2S plans and narrow it down.  We had that
conversation last week, so check the archive.  A typical VW is closer to 160
pounds.

I plan to build something similar, but with Corvair power...

KR> Jabiru 2200 - KR1

2015-01-14 Thread Chris Prata
Couple things, I have a Jab 2200 on my current plane (Avid Mk4). I was thinking 
of selling the avid and purchasing everything needed to build a KR1 with the 
proceeds.  One of my EAA buddies remarked "no one builds those anymore". To me, 
that means nothing. The KR has great looks, performance, and ease-of-build. I 
found a page somewhere that had numerous single seat planes that were 
supposedly "better",  but none looked as good, or had the features. 
I believe that a KR1 with the 85HP Jab and the Diehl wing skins at full length, 
would cruise far and climb fast, and stall slow enough to be LSA. The Jab 
weighs 140LBS, which I believe is less than a Revmaster type VW and prob about 
the same as a minimal VW engine.
I wonder what engines have been used on the KR1 though. It seems there are so 
many more KR2's, for example youtube has almost no KR1 vids, which is too bad...
It also would be great to know if any KR1's are flying with the Diehl wing 
skins not cut down, and what the climb and stall speeds are.
One other thing I wonder about is how well they recover from a spin. (If thats 
an issue I'd just put a BRS on it, or wear my emerg chute)
