Print Instructions (MUST READ):
All the fuselage parts are SOLID so you must print with 0% infill! All settings below are in Simplify 3D. All parts printed in PLA.
Fuselage Nose:
Orientation: Set it motor mount face down,
Length ( Print Height) = 180mm

Motor mounting holes: These are under sized so you can drill them to the correct size. I went with 10mm for the centre hole and 3mm for the screw holes.

The elevator is printed with a live hinge, if you find this to stiff cut it off and hinge with tape.

The one pictured is to small. I modified it to make it bigger.

Wing Section:
This was never meant to be printed it's just for show. Mine will be carved out of solid balsa as per the pics. Print it if you like, spar / joiner hole is 4mm.
