I am getting ready to order a Matco tailwheel, and I was wondering if anyone
could give me am idea of what spring to get. One leaf or multiple leafs. The
experimental tailwheel spring at acs is one leaf. I see a lot of pictures

Fellow Pietenpolers,
Attached in a pdf file is the second update of our testing to determine
the differences between the Pietenpol and Riblett airfoils. Search the
archive for the first posting last month.
The second posting is pretty well self explanitory of what we did and
the results we found.

Hi Guys,
I have a wood and fabric experimental I have been fixing up (last owner quit flying
about ten years ago) and I need someone to do a condition inspection on it.
I live in the Norfolk, VA area. I have contacted a few A&Ps but the ones I
have talked to say they know little about wood and fabric and won't do an inspection.
If you know someone in my area please email me direct.
Thanks
Rodney Hall

P.F. and Don,
Like Brian has said and others agree, thanks for doing the study. I know that it
required a great deal of time on both your part. I, for one, found it interesting
how the comparison turned out, but I think you said it best when you said-
"Which airfoil do we recommend? Thats the builders choice. Either one will work."
And I think that that is the message of your study- choose the one that you want,
and be comfortable in the fact that they both work well.
Thanks again for your hard work and desire to share with the rest of us.

| Subject: | Re: Second update on comparrisen testing of Pietenpol |
and Riblett airfoils
Hi P.F.
So, did *both* the Riblett and the FC-10 plane have the same rate of
climb? Did you put VGs on the FC-10 plane?
As always, this is great emperical data and I'm glad you're presenting
this for the edification of the rest of us.
Next question, what's the stall speed of each ship in similar w&b
configuration?
Thanks,
Dan
PS I hope you're not including me in the "Riblett should fly rings
around the FC-10" camp - I just simply ran both through the XFoil
computer analysis and determined that the Riblett should do "a little
bit" better wrt L/D at cruise and during climb-out.

| Subject: | Re: Second update on comparrisen testing of Pietenpol |
and Riblet
P.F. and Don-
I wouldn't say that there is little to no benefit of using the Riblett. Here's
a snip from a post that I made in May of 2008 on the subject:
"The Riblett "612" airfoil is very similar to the NACA 4412 airfoil that has also been discussed here. Both of those airfoils are deeper than the Pietenpol, allowing for lighter spars and ribs, increased volume where a fuel tank can go in the wing, and both of them have less undercamber than the Pietenpol airfoil. With a 60" chord, a 12% airfoil is a bit over 7" deep as compared with the Pietenpol at 4" deep. There is an image of the NACA and Riblett airfoils at http://www.flysquirrel.net/piets/airfoils.jpg"
By the way, I echo the questions that Dan Yocum asked, especially- did you by any
chance check stall speed with both airfoils?

Everything seems pretty normal right now. No rogue processes and the network connection
to the Internet is very lightly loaded. I tried surfing around the
Matronics Forums and that seemed snappy. I tried using the List Search Engine
and was getting really good search times (<3 seconds on the RV-List).
Maybe your local Internet connection is having an issue?
