| Subject: | Corvair College #31 in Barnwell SC is not far off |
I just got through reading Mark Chouinard's synopsis of his Corvair College experiences
and thought I would add that CC#31 is about 5 weeks away. If you are
building a Corvair engine - go. If you are thinking about building a Corvair engine
- go. If you are building or flying another engine type - go. Just go!
You will learn a ton about engines in general, Corvairs in particular. You will
meet no finer gentleman than P.F. Beck. And you will be around close to 100
people that love the idea of building their own airplane. Just a great group of
people. It will be the most fun weekend you have had in a long time in aviation.
Here is a link if anyone wants to read more about it-

Michael, I am at the point in my building where I need to fabricate the
landing gear/wing strut fitting shown in your post. I need some dimensions
of the individual members of the fitting. Could I use 2- and 1-inch strip
to fabricate them or are some of the pieces larger/smaller? This might
sound basic, but I want it to be strong enough but as light as possible. I
was thinking or using 0.090 thick steel. OK? Chuck

| Subject: | straight axel landing gear fittings---sketches attached |
When I built my landing gear for NX40072 I had the supplement plan from Don
P with the full scale drawings of each piece. I just made card patterns of
each piece laid them on the specified thickness of sheet metal and cut the
m out using whatever tools I had=2C shaped and drilled and they were good t
o go.

Do you have a copy of the plans because all this information, and more, is on there.
If not they are in the flying and glider magazine sold by EAA. Not sure
if you can order full size plans or not.
Mike's modification is the same thickness steel. All that changes is the inner
fitting (tabs get bent down) and the additional piece on the inside/top. Just
make this piece so it fits your plane.

Chuck-as Chris said, the straight axel gear fittings are shown on the plans
. I modified mine slightly as shown in my sketches but they are
basically what is shown on the plans.

| Subject: | Riblett 612 Incidence? |
I have found various threads discussing this airfoil and I just have not found
a concrete answer to the desired wing incidence while using the Riblett 612. First
let me add that my project started from a set of GN1 plans but, I am going
to use a different strut design similar to the baby ace. This kind of strut
will not allow for ultra easy incidence adjustments to be made so I need to get
this as close as possible in the wing and strut design from the start. I have
the riblett 612 designed with 2deg incidence as of right now. Here is a layout
of what I have so far as well as a Cad model of the steel fuselage that I am
working on. I will also be building a 87% cub steel tail group as well. The
plane will be powered by a BMW R1100S engine which is just shy of 100hp.

I just spent lunch hour looking thru all of Jack Textor's build photos and
after wiping the druel from my face I can, without doubt, say
that Jack's workmanship is the finest homebuilding I believe I have ever se
en. I can't wait to see this load of sticks and fabric fly into
Brodhead someday.

110% agreed. His building pictures are the first I look at when I have a
question. Great job Jack, hopefully someday we will meet.

| Subject: | Piet vs. Riblett angle of incidence----from the archives |
via Bill Church
For those of you who missed this most excellent post (and calculation---tha
nk you Bill!) from Bill Church on July 4th
it might be of possible interest for those using the Riblett airfoil.
Mike C.
Bill writes:
There was a discussion about wing incidence about three years ago, and at t
hat time I created a couple of drawings to illustrate the relationship betw
een the cabane strut lengths, and also between the chord line vs the bottom
of the spars. They are attached again to this posting.
For the "to the plans" Pietenpol, the 1" difference in cabane struts create
s a 2 degree angle. Added to this is a 1 1/2 degree angle formed between th
e chord line and the bottoms of the spars (since that's where the cabanes a
ttach). So the effective angle of incidence between the airfoil chord and t
he top longeron is 3.5 degrees.
For the Riblett 612 airfoil, there is a 2.1 degree angle between the chord
line and the bottoms of the spars. So, if a Riblett 612 airfoil is mounted
on "stock" cabanes (front 1" longer than rear), the effective AofI would be
4.1 degrees.
If the front and rear cabanes are made equal lengths, with the Riblett, the
effective angle would be reduced to only 2.1 degrees - almost 1 1/2 degree
s less than the "to the plans" Piet.
In order to produce the same 3.5 degree angle, but using the Riblett 612, t
here should be a difference of approximately 11/16" difference in cabane le
ngths (front vs back).
Food for thought.
Bill C.

I am located down in Leesburg, GA. I grew up around homebuilt airplanes yet really
never became interested in building my own until now. I have been in the model
airplane industry off and on for over 14 years so i figured its time to design
and build a real one.

I just finished creating a 3d model of the scaled down piper cub vertical/rudder.
I still need to determine if I am going to cover the vertical separate from
the fuselage or cover it as part of the fuselage. The junction of the vertical
and the turtle deck stringers has yet to be addressed.
