Weird... My drawings 4/06 (SP) doesn't have information of jury struts material.
Even drawings dated as 2003 doesn't include it. Older CH701 (non SP) uses
one bended 4130 pipe.
Is it a same 4130N or is it 6061-T6?

4130 is very strong "Aircraft" Chrome Molybdenum steel, 6061 is
medium strength aluminum.

Hi Jari,
My drawings (4th Edition, 6th printing 02/2002) page 7-V-10 shows:
NOTE: ONE PIECE WING STRUTS 4130N ROUND SEAMLESS TUBE 1.125"OD X 0.035"
3SP JURY STRUTS -- .500"OD X 0.035" (8 REQ'D) -- 6061-T6 ROUND TUBE
4SP JURY STRUT ANGLE -- t=3D0.025" 6061-T6 -- (4 + 4 BRACKETS REQ'D)
5SP JURY STRUT BRACKETS -- 4130 t=3D0.050" -- (2 REQ'D)
6SP JURY STRUT BRACKETS -- 4130 t=3D0.050" -- (2 REQ'D)
7SP JURY STRUT CAP -- t=3D0.250" 6061-T6 -- l=3D21 (12 REQ'D) l=3D38 (4 REQ'D)
It looks like for the actual jury struts (3SP), mine indicates 6061. I have also heard that for the Front and Read Struts, they have changed to streamline 4130 material, but I don't know if that is true.
Good luck,
Keith

I've got a pre SP and mine is 6061 (though not bended, I didn't much care for that
design). My neighbor built an SP kit and his struts were also 6061 (and a much
better method of strut attachment than the early drawings).
