Alexey,

Since your construction technique and planes are so unique this will answer many questions I have.

Thanks for sharing,

George

Pierced the fuselage tube with two carbon rods.
Make a right wing.
All this is done in one day.

I really appreciate this build sequence of nice photos.

If you know, how did you decide how many cross-braces, or whatever you call them, to use? I.E. How did you know to use, say, 13 X along the fuselage, not 6 or 20? Is there perhaps a preferred crossing angle between the various carbon pieces? I see several different crossing angles at different points along the fuselage length.

Is it based on a "good" maximum unsupported length along the fuselage exterior carbon?

Is it a That Looks About Right (TLAR) judgement?

My thinking is that perhaps you could use quite a fewer X and save some cost, labor, and weight. But then it would be less stiff. But in some places, less stiff could be desirable for impact-resistance.

Perhaps you did a finite element analysis of the planned design and then modified it for some measure of merit, like uniform displacement or twisting under load? Probably Not! :-)

Thanks so much!
Jim

Beatiful!

The carbon tube looks a lot like a F1G tail boom, any relation?
