BINGO !!
This is one of those times when I truly value this forum...I've been
following this thread w/ only mild interest...to this non-engineer's
mind, the assumed function of the lift pins was primarily to set and
maintain the wings' AOA. But Ian's comment got my attention, and I
have a newfound appreciation of all the posts leading up to it.
=46rom the get go, I've been embedding components within my mono which
would facilitate potential conversion to Bob Berube's tail dragger.
I'd planned to add the recommended layups intended to transfer LG
loads to the fuselage sides which have the effect of stiffening the
sides of the fuselage. While I do not have the expertise to comment on
the implications such layups may have on the loads ending up on the
forward lift pins, I now will hold off on these layups...they can,
after all, be easily added in the event the mono-ground handling
proves troublesome...I may even get airborne a week earlier!
