I have been following this problem and will come to it very soon now.
My understanding is that there is no particular difficulty until you fix
your fuselage module into the hull or lower fuselage moulding. At this stage
you unintentionally bend the foundation of one or both of your bearings and
you mysteriously have tight controls.
I am wondering if the cockpit module ought to have some additional
stiffening in the area near the bearings, or much care must be taken in
fitting the cockpit module to avoid distorting it, or the final fixing of
the bearing seat should be left until after the cockpit module is fixed into
the bottom fuselage moulding.
I look forward to hearing more from those who successfully mastered this
one.
