wing mounting Moose

Post by Scott & Leere' Aldrich » Sat Feb 18, 2012 12:01 am

Wayne as far as the Moose wing rear attach, I still don't get it.

Seems to me there is no place for it to float , how can it move fore and aft
even without being tight? If the forward attach is tight it seems to me the
only direction the rear attach would try to go is toward the center
(compressing the rear carry through) whether it is tight or "floating"
(unless I make the holes oversize I can not see it sliding along the bolt).
I don't understand why I wouldn't want spacers in the rear attach bracket to
keep them parallel so I can tighten them without deforming the bracket. The
3500 upgrade changed the rear spar fuselage fittings from aluminum to steel
ones, appears this did nothing due to the carry through being the weak link.
I think the rear carry through needs to be beefed up. But as I said, I
don't get it, so maybe I don't get it...

BUT, you Moose guys remember that the front spar attach fitting is to be
tight in the carrythrough and spaced so that the Rear attach fitting is
centered and >FLOATING< inside the fuselage fittings. NOT HELD TIGHT!
Bolt/nut is to be tightened only to be snug, allowing the fuselage fittings
to stay parrallel to each other. This leaves a small float gap on either
side of the wing fitting and allows the loads to be transfered to the front
spar fus carrythrough, instead of the rear fuselage attach carrythrough.

Hi Rallph
When putting the wings on the Elite the idea is to set the for and aft
location based on the rear spar fitting as you do not want any bending or
preload of the fittings. It is best to put the tail up and to level the
airplane as the weight of the wing will cause it to slide back. You may
find
that the wings have different front and rear gaps inside the cage main
spar
attach points don't worry about it the airplane will not know the
difference
and it will fly just fine. Make your spacers up so they fit snug between
the
front spar and the cage as you do not want to bend the attach points on
the
fuselage or have the wing move

wing mounting Moose

Post by Wayne G. O'Shea » Sat Feb 18, 2012 12:01 am

Didn't make a lot of sense to me when I was told this by Brian Godden in the
first place, when I was questioning the thicknesses of the 3500 steel attach
fittings for the wing and the new ones for the fuselage as well. Was told
this was done purposely as "load calculations showed it was better floating
than tight" (and they want the extra wing loading going into that nice .063
leading edge doubler and the beefed up front carrythrough/wing attach
fittings). Somewhere all the measurements are in the archives, as when they
were all clear in my mind I put them there so guys could figure out the
final dimension of the front steel insert bushing, for the front wing attach
fittings. We are only talking a small amount of free play in the rear
fittings, but Brian was adimant that it wasn't to be tightened up nor were
spacers to be used.
