Mike,
Bernard Pietenpol was a master of design. If he put four pins in there, then
there was some very good reason for it. Sometimes, the purpose of a design
is not readily evident. The plane can certainly be flown if only one half of
the elevators (flippers) is operational. Power setting can also be used for
pitch control.

If we think a moment: there are 4 cables going back as the elevators
are separate each side so 2 for the top and 2 for the bottom, then
of course there are 2 cables going forward to the stick, and then you
might have 2 cables going forward for trim if you have it. I don't have
the plans right in front of me, they are in the shop; but that might
total to 6 holes (or 8 holes with trim) for all the clevis that you might
need, or maybe just 4 holes if you double up the cables going back
onto the same clevis.

or Pietenpol projects in the Nashville TN area?
Thanks,

| Subject: | How to License your Homebuilt Aircraft |
This is an announcement that www.HomebuiltHELP.com has just completed production, and is proud to announce the release of their latest DVD video presentation: "How to License Your Homebuilt Aircraft". (for the U.S.)
To the best of my knowledge, this is the first comprehensive DVD video that explains
in detail the complete licensing process for experimental amateur built
aircraft - showing what/how to fill out the forms, and also demonstrating new
capabilities such as reserving an N number by going online and using the FAA website.
I'll leave it at that, as full details are available at the www.HomebuiltHELP.com website. In keeping with the list's guidelines, this will be the ONLY post on this matter, and I hope it was valuable to some Pietenpol builders.
Thanks!
Jon

To you guys building.... keep it up. It took me 9 years, 6 months and a
couple of days to get here! Once it's done it's really cool to see it fly.
I'll post some pictures to my website as soon as I can.
Bert
Congratulations Bert, it's got to be a great day and a wonderful sense of
accomplishment. Mine is not far behind. Taxi tests revealed some problems that
are just about corrected. They involved wheel bearings and bad geometry between
the tailwheel control arms and the rudder conrols arms. Look forward to the
photos. Don H.

Congrats Bert: 9 yrs. uh? Now I feel a lot better. It will probably be
that long for me to. What are you going to build next? Leon S. 6 years
and counting. Do not archive.
