| The Incomplete Guide to Airfoil Usage |
Here is your chance to check out the airfoils used on most of all the famous
aircraft in our history like the famous P-51 Mustang WWII fighter and lots more. Check out David
Lednicer's site.

| NACA Airfoils (Other than from NASA) along with other airfoils |
You can download the airfoil coordinates and pictorial plots of the airfoils
listed on this site. Very useful as this site lists some of the most used by classical and general aviation
from its beginning. This is a Japanese web site but English is also shown with the descriptions.
Of special interest for the Flying Flea community, NACA developed two trailing
edge reflex airfoils early in their studies. These are NACA 2R(1)12 and NACA
2R(2)12. They are available to download from this site. The 2R(2)12 is the
preferred one.

A CAD Drawing Program family that is Very User Friendly
For those of you with a little interest in the drawing end of designing, we would just
like to let you to know that we use the Ashlar-Vellum families of CAD programs. The
Graphite program above also contains full 3-D wire frame capability.
The documentation books that accompany the software are the best presentations,
step by step, we have ever seen. The customer support part of it is equally
impressive. There is a CAD program for everyone, from simple and accurate
drafting to the most complex 3- dimensional solid modeling available.

Epoxy Adhesive ....
There are several epoxy manufacturers out there but the West System has been used longer than all
the rest. It is proven and is even recommended by Burt Rutan.
It has been used for structurally bonding together the huge wind turbine electricity generator propeller
blades used world wide in the windiest of conditions and not to forget ..... Thousands of sail and power
boats. It is especially recommended when repairing dry rot in marine hull applications.
With the Gougeons metered can pump systems, you cannot miss the right mix ratio between resin
and hardener. This is a highly recommended bonding system.
Tip No. 1: When you just need a small amount of epoxy and the pump is primed, push each pump 1/4
or 1/2 way down. The mix ratio is maintained and you won't waste any resin. It's expensive, so save it.
Tom at Gougeon Bros. Mentioned that their new pump manufacturer modified the pumps and
accurate full strength dispensing can no longer be made this way (non-critical jobs can still be done
this way). Here is Tom's suggestion:
"Make accurate small 5:1 batches using a modified plastic syringe. Cut the tip end of a syringe
completely off. This makes the end of the syringe look like a cut off piece of clear plastic pipe. We
measure 1-1/2" back from the end and put a mark there. We measure back 1/4" from the end and put
another mark. Pull the syringe plunger down to the 1-1/2" mark and fill it (using the resin pump)
between the 1-3/4" and the 1/4" mark. Now top it off (using the hardener pump) with the remaining
1/4" of hardner to complete a perfect 5:1 ratio. Push the plunger down to dispense the material into a
mixing pot and scrape the plunger off on the tip of the cup to remove the rest of the epoxy. Store the
syringe for future use."
Tip No. 2: When using brushes with this epoxy, after application, leave the brush coated with resin and
wrap it in plastic wrap. Place it in the freezer and then place it in acetone when you want to use it
again. You can reuse the brush 3 to 4 times this way until you have to throw it away. A great savings in
the cost of brushes.
