Good grief!!

Almost two years ago, while preparing to install my fuel tank, Europa
confirmed that the then current production tanks do NOT require any
conditioning prior to installation.  I was informed at that time that there
would be a revision to the manual deleting the instructions about doing so.
Manual revisions seem to have a rather low priority.

On my fuselage many of the trim lines were likewise "difficult to see"
mainly because there were none.  This was especially true of the cockpit
module.  The mating parts of the fuselage top and bottom will overlap by
about 20mm so cut accordingly; note, however, that there is a bit of a
joggle that is not part of the joined surfaces so use that as a reference
---From which to measure the 20mm.  Perhaps it would be best to cut oversize
and then perform a trial fit of the top to bottom to verify that there is a
20mm bond zone along the entire length of the bond.

In the cockpit module it is more difficult to judge where to cut without the
scribe lines, but only at the footwells is it critical where you cut.  The
horizontal cut at the forward end of the cockpit module is the aft end of
the floor (installed later) upon which the ruder pedals are mounted so this
cut must be horizontal, and also at the right height to keep the floor
level.  I left it high and trimmed as required when it was time to install
the floor, which is perhaps the preferred way to do this since the location
of the floor determines the location of the horizontal axes of the rudder
pedal shafts.  The manual implies that these are not related and fails to
caution about the elevation of the floor being important.  I suppose that is
based on the obviously erroneous assumption that there are scribe lines in
the moldings.

If you have a tri-gear you MUST have the crosses to locate the fuselage
centerline and to find FS70 in order to locate the main gear axles.  I urge
you to address this with the factory before you proceed if yours is a
tri-gear; for the monowheel I don't know the consequences of missing
crosses.

Hi on this year,

In the manual they say (page 10-2 issue 2/ XS) "tank will expand over of
period of 3-4 weeks once fuel is introduced and this should take place
before tank is installed into cockpit module".

What is that meaning?

Should I fill the tank with something over mounth before istalling or what?

Also, "trim lines are to be found on the mouldings but are difficult to see"
(page 11-1).  Can not see any trim lines, no small crosses on the aircraft
centreline.

Trim lines for windscreen are 12-13 mm, for door 20 mm. How much for the
bottom moulding???
