5.1 Wing assembly Piper J-3 Cub
Glue wing parts wing CENTRE and L1-L4 together. The new 3DLabPrint lock system will help
you. Repeat for the right side. Glue both halves of the wing together. Use the CA glue,
(position locks and wing pins will help you to align the parts), and use activator to speed up
the glue curing. Press in and glue a piece of PolyAir, PLA, PETG or 1.5 mm carbon rod into the
top and bottom openning to create a wing spar and improve the rigidity of the wing.
On a flat surface glue the ailerons L1-L3 and repeat for the right side. Use a filament or
suitable 0,8mm - 1,5mm carbon rod as a hinge for the ailerons. Just slide it in, there's no need
to glue the hinge for easy aileron or servo replacement. Wall thickness should be 0.55-0.67
