Albeit a counterintuitive task, playing with polars (airspeed/rate of descent and lift/drag coefficient)
gives you a glimpse of a glider performance.

A good description of shock cords is there

Thanks for answering, PTC did the Pro Engineer CAD suite (and recently Onshape Online CAD system) so I bet MathCad is a good product, and certainly old version too.

Ask help from a local EAA counselor for needs of restoring it (fabric, engine, instruments). Nevada, IA is central, and I don't know if it's wet or not. I don't know if an emeraude is rare on the...

Fitting Graham Lee datasheet with rotax 503 numbers gives you a CD0=0.07 (parasitic and interference

I'm interested in as strength as possible so 0.083" with wood doubler is my choice.
Thanks for sharing but this tube is for wing spars, 0.083" wall is for strength, (0.035" and 0.065" wall is too thin, 0.125" is
too heavy).2"-1/2 OD is for leading edge radius.
I found https://www.tubeservice.com/ (from a thread on homebuiltairplanes.com)
This reference is on their catalog.
If you have another one, I appreciate your sharing it if you want.
Thanks...
I'm looking for 6061T6 2"-1/2 OD 0.083" wall tube and can't find it. (0.065" or 0.125" wall
only). I looked at aircraftspruce, wicks and onlinemetals. Have you some addresses ?
Thanks in advance...
"Design of light aircraft" from Richard Hiscocks can be an entry to design tail and have

Thank you for your post Mike.
Did you follow Earl Luce advices on cutting 4130 tube (videos
on eaa.org) or did you produce your own methods (notcher
lathe or others) ?
No answer from Mike,...
Thank you. I saw your logs of the Buttercup project on wingsforum, and its quality is impressive.
I couldn't imagine anything better than this book for my issue. Thank you for your help.

For sure, thanks for the information. I'm a great fan of wittman designs.
