Total disagreement. Those plastic films add NO torsional rigidity.
Fibafilm is better, if fragile. The best, provided your model will work
with a textured surface, is Ikarex (a polycarbamate coated polypropylene
kite fabric). The stuff is bullet-proof, has great colors, and is much
less flexible than any of the monocote type films.
