Covering
Covering of 3D printed planes is done the same way as you would do with common balsa RC plane.
It is important to test film covering on testing part before you start.
If you have no experience with film covering my advice is to try more brands of covering film
before you get frustrated. It is easier to work with some than with other. I tested couple of brands
and in my opinion
solarfilm lite
is the best option for this kind of plane.
My recommendation is to cover wings after they are fully assembled (center wing, tip wing and
aileron are glued together). It is a little bit more demanding but it is definitely worth it. Otherwise
you are risking that when gluing aileron to hinges and hinges to wing tip, glue might leak and
spread all over hinge pin which will block the hinge and aileron would get stuck.
The same is valid for vertical stabilizer covering. Cover it after you glued on the moving part with
hinges.
Fuselage has holes in order to reduce weight and make printing easier (smaller chance of cracking
or warping). These have to be covered as well (except for side vents near front canopy).
