Tissue?

What weight tissue do I use to cover an all sheet plane?

Tony

I have always used medium for open bays and light for covering over sheet.

For my latest, using Godzilla's Polycrylic process, the light is easier to use--the medium seem to "fuzz" a bit more and ends up harder to get completely smooth and flat.

FWIW

I dothe wood with four costs of sanded between coats of Nitrate followed by Japanese tissue applied with 90/10 thinner/butyrate dope. Then four coats of thinned butyrate, prime, color.
Japanese tissue is very light and dense, but it is very easy to sand through.

I agree with Ty. My (Late) Tempest had silkspan on the open wing bays only, with Jap tissue on ALL the other surfaces and edges. Complete any surfacing such as resin, etc first. If you can find genuine Jap it's better but the current version will work. Get good base of well sanded clear (nitrate is best) underneath. After sanding be sure to add another coat or more for attaching ( about 50/50 thinned works here in Minnesota), allowing it to dry , then apply the tissue with straight thinner or not over 10% dope. Apply the thinner over the tissue so it soaks through and rub through gently with a finger. "Dice" the edges as you go with lots of cuts. A double edged razor blade used with care works best for this . force a second coat of thinner through the tissue with your finger for good adhesion. Us lots of strips and pieces--the material is so thin the seams are no problem to hide. White is not a good choice over balsa since you can't see where you've put it.

This is light, easy, and a great base for sealer, etc. You'll need a lot less primer and sealer and should see no grain at all.

So which of the items here:

Would be best to use?

Of all those listed, the Esaki tissue sounds like the "right stuff". All the other listings make me want to get back into Free Flight !!

Hey, Ty, how about some of that 5 micron mylar? I've used some of the 15 mike mylar, and if you think Jap tissue or silkspan are a challenge... Sure would be light, just don't drop your glow driver.

Right - I've got some light Esaki tissue - green for the wings and yellow for the fuse and some butyrate on the way.

Any tips?

How do I handle the (fabric) hinge areas?

I gather that you have already applied the fabric hinges. If not, do so before you cover with the tissue.
Then cover over the hinges and all.
