Hello, all
Has anyone had difficulties with the upper engine fittings and the
longerons?
Something like the attached pic?

Steve,
Not trying to be a smartass but have you tried measuring it? If it is in a location
that is hard to reach, press some modeling clay into the the hex and pull
it out to measure the clay impression.

Carlos,=0A=0A=0ADid you build the engine mount fitting yourself or did you
buy them from ZAC. In any case, check all the angles of the mount fitting a
gainst the plans, if they are ok, check the longeron conforms to the formin
g template. If the mount fittings angles does not match with the plans, tha
t is your problem. Judging by the picture, it seems there might be an error
in the angle formed by the outside edge and the front that attach flat to
the firewall (where the bolt goes). The problem could also be that your lon
geron is over bent.=0A=0AI'm at the same stage in the build as you are (but
I'm building an XLB) and I have clamped the mount fitting to the longeron
and there's no misalignment. I built my engine mount fitting (have not weld
ed it yet) and the angles are exactly as per plans.-=0A=0A=0A=0AWilliam D

Hello, Bill
Thanks for the comments.
I am building from plans, but all the steel parts I buy from ZAC -
including the fittings.
I have been through the same reasoning you have.
I checked the longerons a couple of times, and they match the plans.
I don't have the drawings for the fittings (6B6-4), only the right bottom
quadrant of page 6B6, which shows the positions of the holes on that part.
However, by comparing the fittings (6B6-4) to the longeron template, I
believe they are correct.
Which leaves me with the possibility of a badly shaped rear fuselage...
Which I find hard to believe, as I have verified measurements more than
once.
Obviously I am missing something - if all the parts are good, how can the
assembly be misaligned?!
If interested, I uploaded a few pictures to zenith.aero:

Cheers
