Hi Joel,

Thank you!

I don't consider myself an expert pattern plane designer. Instead, I did a lot of research, including collecting and comparing data on all the pattern planes I could. Pattern design is actually pretty simple, because the parameters are so well known. Building a precision model, trimming it and flying it at a competitive level is another matter, of course.

In my design, I added two details:
First, I designed it to accommodate several different wing sets, as you can see on my web site. I hope this will let me have the equivalent of several different planes in one.

Second, I enlarged all the control surfaces from the traditional ratios, with the idea of "artistic aerobatics" (some 3D mixed with Pattern) flying. Finally, I kept it at a size that I felt would allow for smooth flying, yet not so large as to require an engine bigger than a .91

I'll have it ready for next season. The King Air project (also on my web site) has all my attention right now, so the "J-45" is on hold for a few months.
