Gentlemen,

I'm now a bit more used to the forum's set-up and as such will keep this thread for any future questions, statements or other issues regarding my intended Sopwith Baby project, so as not to post quite so randomly.

Step (1) of Phase one is completed as of today, as follows.....

The decision to go 4130 tubing for the airframe is solidly grounded for many reasons and is therefore permanently decided.

As for the issue of Al.-vs- wooden wing structures. In speaking with many of you both on and off-line along with the many flying examples out there, the decision in favor of wooden wings is therefore also made.

However, Airfoil section is "tentatively" decided as a NACA 4 digit section as per the following reasoning......

In order to maintain some degree of authenticity but, yet take advantage of better lift / flying characteristics, I don't see another section which can be manipulated to match the original as closely and still do the job.

......Any comments / observations regarding the airfoil choice are very welcome and encouraged.

Regards
