Help! Paper laminate on foam plain board

[Nisar]

Hey there, I have foam boars which are not paper laminated.. basically just a board which can easily snap! Currently I am taping the plane once the model is ready.. but I want to laminate brown/craft paper like Flighttest boards on 20"x30" sheets for increased strength.

Thinking of diluting pva glue and sprayng for easy and even spread then paste the paper. Will it work??

It will be an ongoing process for me as Im thinking to use laminated sheets for my future projects 😓
Thanks a bunch!

Experimental airlines also had some great stuff using tape.

its depending on how "stiff" the pva glue gets. It needs have some flexibility for shape foamboard rounded.

And the failure mode of taped DTFB is the foam core collapses and you get a dreaded case of wrinkles. Not sure glue would change that.

This guy thins his white glue with water, then glues brown paper over foam to make airplanes

This looks sturdy. Should try this on sample to test strength. Thank you @kilroy07

Tge problem with pre taping is all the cuttings has to be stright and aligned with tape direction.. this way I end up using more foam boards than required. But this works best with wings though 👍

@Piotrsko ao do you think even after sticking paper I get wrinkles?

I can tell you personaly that gluing paper onto foam works great.... I don't have access to fb so I make my own.... I use flour glue 1 cup flour to 4 cups water.... Cooked for 3 min, I then spread it onto the foam and stick brown craft paper onto it.... Really strong, maybe even stronger than dtfb....

Here is proof

Why does anyone need proof?

This looks great. I should try this. I made some chucks last week and now in the process of taping them.

See in the pic how tedious it is

Im a novice and have never flown any rc plane. Just following flitest build videos and hopefully will make something soon and post pictures 👍

Cool.... Quick tips... Larger flies easier.... And as a trainer I must suggest the ft old speedster... If u wanna use b power pack... Leave it as it is....
If u wanna use c power pack then scale it up to 130%.... Mine is a 130% and it flies super slowly and gently... Plus it can take a big beating....

The chucks in progress along with a trainer and ft mini Vector.. just tapped this tint one today still WIP. I think working on bigger models is much much easier than these tiny ones! Will post updates as I progress.
