The first step is to trial fit the
assembled wing fold unit to the center
wing spar. Every spar has been drilled
and sanded to fit the wing fold “claw”
before the joining process of the
center wing’s mold halves. However,
it is quite possible that slight
adjustments need to be carried out,
such as sanding or grinding mounting
surfaces and holes, especially for
alignment purposes.
Unbolt the up-lock and remove from
the sliding pin for now. The up lock
only works properly when the
pressurized cylinder operates the
movement of the aluminum stud. If
the aluminum stud is moved by hand
during the installation and the sliding
pin is not in the upper end position of
the slot, the aluminum up-lock feature
can interfere with the pin and get
damaged. As soon as the operation is
carried out by the cylinder, forcing the
sliding pin into the end positon before
any rotating movement is initiated,
this problem will not occur anymore.
Use 6x M5 bolts and stop nuts to bolt
each unit in place. Check the
alignment in the down and up folded
position as shown on the photos.
If the alignment is slightly off,
honestly, there is not very much to do
except a lot of grinding, which in
return would weaken the spar
substantially. Slight misalignments
sometimes occur in the up folded
position, when the spar twisted
slightly during the mold joining
procedure. Our recommendation is to
accept it, as it does not have any
structural or aerodynamical effects in
flight, and it is usually not visible at
all when the wing is mounted. You
should also check the distance
between the up folded wing stud and
