Covering material

[leccyflyer]

As noted above nylon is very very tough, but it takes so much dope to make it fully airtight and smooth that it seemed to always end up very heavy. I used to cover my spectacularly unsuccessful control liners with it and the comment about it making a nice ready-made carrying bag for the bits is spot on.

Good video on applying tissue over mylar here: https://www.youtube.com/watch?v=T2dx5MGD4_c

 

This thread features applying polyester dress lining over doculam, Post 16. https://www.rcgroups.com/forums/showthread.php?3845901-VOK-2021-Veron-Deacon/page2

 

AFAIK the only difference between mylar and doculam is that doculam has a heat sensitive adhesive backing but mylar hasn't.

Leccyflyer, lol, yes i can remember a control line model i had with nylon covered wings, after a few crashes it rattled where the internals had disintegrated but the covering still held its shape. 
i do have a mostly finished Tomboy in the workshop covered in tissue, already has holes from hangar rash that need repairing, forgotten how fragile it is.

Have a look at Diacov 1000 from Sarik. Really good on compound curves and the seams disappear, it's light too. You need a very sharp scalpel to cut but I have found it to be much less fuss than any of the films. I haven't tried painting it yet because in the end I liked the natural colour on my glider
