Does anyone know the length of the plug that is in the lower end of the
struts on the early series? I had to push these plugs all the way in
the struts early on in order to set the dihedral to the correct specs.
Now I need to know where the end of these plugs are. Removing one is
not an option.
Also, what grade aluminum is the strut and the plug made from?

I fairly certain that it's 2024 T3.

No, neither the strut or the plug are 2024...they are both 6061-T6


Can you confirm this?

Sorry Guys,

I don't remember using any 6061 solid rod in the Lazair.

Not that it matters much.

We used 2011-T3, it machines a little better than 6061 and it was cheaper. Strength was not a problem.

6061-T6 and 2024-T3 are OK replacements.

hey dale , thanks for that . I have made many plugs for the lazairs and used 6061 t6 stock and had zero issues. The struts tubes at 6061 t6 and readily available as well from most suppliers. Prolly an area of concern should be the corrosion that happens around all bolts with out zinc chromate as well.

Thanks Dale, Ozzie and all for the reply about the strut plugs. No Ozzie, now that I know what the aluminum alloy is used in the strut and plug I am going to replace both.
