Classic Airframes Hudson Spar Modification
To Ensure Wing Strenght
- Cut Spar from Plastic card and taper the top side to fit inside the wing.
- Install spar through the fuselage in line with the panel line between the
first and second windows.
- Do Not install the engine nacelles until after the wings are attached.
This will allow you to apply glue to the inside of the wing/spar joint.
