Test fit the hinges in the hinge slots for each control surface and its parent part, this will make
gluing the control surface easier when the time comes.

- Do not force the hinge if it is

too tight. Loosen the slot by gently inserting a stanley knife.

Using the LW-PLA as a hinges:

From the off-cuts from the fuselage false floor, cut small sections of 15mm x 7mm with the
7mm side being against the grain of the layers. Test fit the pieces into the hinge slots of the
control surface and stabiliser or wing.
