fanfold substitute
 
I searched but couldn't find what i was looking for. Can I build a plane that was meant for fan fold out of posterboard with the paper removed? I was interested in building the 3dx. Can I use the same glue on it such as welders. hot glue or contact glue?

You can substitute Dollar Tree foam board to substitute for any sheet foam. Keep in mind that when you take the paper off it loses a lot of strength, take the paper off both sides its really weak.

Would a small plane be too heavy to fly with the paper still on?

Depends on your power system. Most of us remove all the paper from DTF. Two trite sayings, but undeniably true: "build to fly, not to crash" and "lighter flys better".

Thanks!...I have never built any scratch ones before and saw all the fan fold stuff and had to build one. I went to lowes and Home Depot with no luck. I saw I can have it shipped to lowes for free but it's a month out. I'm going to order some if I like the way the one I make out of foam board flys. Or if anyone knows somewhere that stocks it in Bakersfield,Ca it will save some hassle.

Don't use the paper coated stuff myself but read a lot on here and it seems people often remove all the paper. For a number of reasons. It comes off when wet and it's heavy being the most common. Some of the folded wing designs keep some of the internal paper on for strength.
In order to regain the lost strength without regaining the weight people then cover with packing tape. Coloured for easy finish.
As with everything on here there are many opinions and techniques but that does seem to be the most common thing I read.

The currently stocked foam at Dollar Tree stores that is marked "Readiboard" has paper that can be cleanly and completely removed without any wetting or prep work and doesn't leave any residue on the foam. It just peels right off. The previous kind was a real pain to strip, it almost took all the fun out of using it for me.

The genuine Elmer's foam board is still hard to strip and I wouldn't use it unless I had to to get the thicker foam. The Elmer's is sold in more than one size, color, and thickness but is several times the cost of the Dollar Tree Readiboard. The Elmer's 3./16" board is the one that best compares to Readiboard when they are both stripped.

Good advice from TCF and Jack (and Djacob as well, "MPF is the best foam for your foamie" but if you're just starting, Dollar store foam is easier on the wallet for a few sheets)

click on my username and scroll down my blog for a list of links to 11 planes all made from Dollar store foam. You can get some ideas for your build from the build logs.
