Ok,, so lets flip the wing over and see what has happened
down there...
Opps,, there is a dang 22x10 Zinger prop in this pic... What
in the heck does a 22X10 prop have to do this the Phoenix
you ask....
Welll,, lemme tell you.. The original Twinstar uses a two part
block for the main landing gear.. The long flat part which holds
the gear to wing and the vertical block to keep it from rotating..
In many cases the vertical block splits or breaks off.. So in giving
this some thought I was wondering what wood I could use that
was strong as heck but not as heavy as a brick... Taa Daaa...
A Zinger prop comes to the rescue...
The pic isn't real clear but the vertical block is a very snug fit
to the long horizonal gear block and it is also has epoxy holding
it to the rib which is lite ply..

(disclaimer: There were no live or usable Zinger props used in the making of this segment )
