I don't have a dog in this fight, but that is the way I also understand the
stall. Angle of attack is the angle of the chord relative to the wind, not a
horizontal line. So if the plane is descending in still air, the angle of
attack will be greater than the attitude of the wing chord.

There is some reinforcement of the bracing for the firewall on the KR2S. I
feel sure

How did you identify the condition as a "tail stall"? What

The KR2S plans call for the same CG span as the KR2, a total of 8"
Take a look here. There are several Flight Information Manuals available
that have that information.
For a Revmaster type carb, turn the fuel on, crack the carb and start
turning. For an Ellison on a cold start, push the primer and crank.

Its easy to measure the AoA on the ground . measure vertically up from
level ground (hardstanding is best) to the centre of the centre section LE
and to the centre of the centre section TE. Divide the difference by the
wing chord and that is the sine of your at rest AoA. For a tailwheeler its

The definition of an aerodynamic stall is when the critical angle of attack
is exceeded. This was a big part of the private written exam. It's all about
the angles and the effect that has on the airfoil. This is why the
application of vortex generators make some aircraft (such as the 150)
The angle of attack is dependent on the 'relative wind' and has nothing to
do with the wing chord reference to speed, attitude of the aircraft/airframe
or anything else other than the relationship of the aerodynamic chord of the
wing relative to the "relative wind". There are a number of
I am not an engineer but I always understood if there is not enough air across
the wing it is stalled. so what does the angle have to do with no air across
the wing? I know if you pull up and block the top of the wing it will stall. I
have stalled the wing at 105 mph and the tail at 115 mph.
Hello everyone;
In attempting to write a checklist for my KR2, I suddenly realized that
I lack any valid "V" numbers for it. If anyone could help, iot would be
very much appreciated!!!
Along the same lines, I've noticed a wide range of pre-start procedures,
and I'm wondering what seems to be
O.K. students, the lesson for today is "stall
angle of an aircraft wing". There will be a test to follow. :-)
I'm guessing our KR is "typical of many airfoils"

Full stall requires ~13 Degrees Angle of Attack. What is your AOA
sitting on the ground ? If it is less than~13 Degrees, Then full stall
is NOT
possible. As Larry says" you are at the SLOWEST A/S possible

breakfast. Since I am putting in a corvair now after having

We will build the fwd deck removable so that should not a problem. But what is
the differents between the 2 and the -2S. We are building a -2 with the -S tail
and stab. So wat need I to do in the front of the Fusselage. Prob some pics
will help.
Thanks

Very true statement Larry. I have slammed my tail on the runway more than

Strange.

I would bond as you have been doing, then, when clamped to way you want it,
I would use a putty knife or scraper
