Simple wing retention

Fri Jan 16 12:49:51 AKST 2004

Wayne, it must be all that good livin' you are doing.  I believe I have been
with you at least 3 of the 4 time and witness this.  The first one was "man,
I just got away with one", the second was, "I can't believe I did this
again", the third was "you ain't going to believe this", after the fourth
time I concluded that the plane gods still believe that Aries is dead and
fail to recognize that you brought it back to life after Hot Springs the
year before (when they were not as merciful).

This thread stirs me....   This is a hard one to admit but last year alone I
forgot to put the Jesus bolt in my Aries 4 times and it survived (4 free
airplanes in a year has got to be a record).  Thank goodness I wasn't doing
a gazillion snaps.  My newest ship is done exactly as Eric described but
with one extra.  I put a red triangle shaped warning sticker over the
J-bolt.  I talk to no-one while I setup my plane now.

I copied Chip's method of one 4-40 on the top and one on the bottom. You
leave the bottom one in all of the time. With fixed gear you almost always
put the wings on with the plane sitting on the ground. In the event of an
"inverted" wing removal you have the option to remove the lower bolt
instead.

In bigger planes, and also seen on a Pappas creation, I use 1/4 x 20 nylon
screws into the wing tube.

Lamar Blair and Jerry Stebbins sell a very nice nylon insert that grabs the
4-40 very well indeed. A very neat homemade option is to use plastic water
pipe. One that has too big a diameter. What you do is cut off a 1/2" wide
piece. Then cut out enough of the "ring" so that it can be compressed and
pushed into the wing tube. A touch of CA and you have a section that can be
threaded and will "grab" your $4000 screw.

Regards,

Eric.

Yo, Anthony ...
That idea makes so much sense, that it hurts!
As the old addage goes, "If you can't hide it, scream it".
Put some sort of trim around it: make it look like a gas-cap,
after all, it's in about the right spot.
Regards,
Dean P.

The last four planes have all relied on the $4000 bolt. The latest has a
great innovation. The bolts are on the top of the wing. I always complained
it is aesthetically unpleasing but pretty simple. Leave the tube in one
panel and the plane comes out of the car to have the wings installed
immediately. Plane gets carried in one piece to pits to be fuelled. One bolt
and I am ready to go fly. If I get nervous and need to check it is right
there in plain sight. Very quick when it rains too!
