Is it OK to use hot glue for the entire assembly? I also have Foam Tac but it probably won't work for the paper to paper bond.
If the paper is left on the outside it will be susceptible to moisture ( even from humidity in the air ) and delaminate .

I use hot glue and Dollar Tree foam board for 100% of my scratch builds .

Consider using packing tape (clear/colored) for the outside for strength. Water, dew, etc. will remove the paper if it is not sealed.

Hot glue will work, but watch the temp and nozzle. Foam safe CA works. Some use 3M77 or similar but I've had some melting with it. I like the white Gorilla Glue but you have to wipe excess and preferably clamp or tape over bleed areas. Best to test whatever you want to use on scrap if it is new to you or the material being glued.

GRN2806, I'm a few miles from you in Brentwood. Nice to see a local on here!

Curious about the type of foam in this pict. Too course for $tree. Looks like regulat styrofoam?

I normally use $tree, but just bought a bundle of pink fff. Thinking about building one of these from it.

Thanks

Well, I managed to maiden it for about 60 seconds.

I was at Flite Fest 2015, slowly rounding the course and minding my own business, when suddenly out of nowhere a Stryker slammed into it! Very frustrating after all the time I put into this, my very first scratchbuild plane.

The plane was cut in half and virtually destroyed. The wing is the only thing that survived and surprisingly is untouched. All else that remains is so twisted from the collision that it will have to be rebuilt in its entirety.

I'm going to rebuild it but now have a construction question regarding the KFM wing.

This wing is considerably thinner than the material used In the original plan. Therefore, the actual step is much smaller than in the original wing.

Which wing should fly better? Should I double up the $tree foam for a better wing or leave it as it is? I would love to hear from those of you who have built the same plane from both materials.

BTW, the Stryker also broke into several pieces. At least I only lost $2 worth of foam!

My very first EzFly was EPP , then I've been building them out of Dollar Tree foam board ever since . I personally don't like EPP .

I think just a single Dollar Tree foam board layer KFm is best - less drag on the leading edge .

Adobe Reader can do scaling up or down.
