$4.00 worth of WalMart foam board ( 3mm depron), some spare balsa and ply ,one 1/4" spruce stick 20" long, power plant taken from GWS Slow Stick, 4ch rx, HS55 servos, 7cell AAA 700mah nimh pack, and you get what you see....30" wing span, 315" of wing area, and 11oz total weight. Its based off a plane called And Now. I took it out yesterday for a test flight. Found that the C/G needs some major adjusting...nose heavy.. but I did keep it up in the air for a bit. Seems very positive on all controls even though I had to keep some up elev. fed in.
I juggled the battery pack around a bit when I got home and will give it another go.

most of the foamboard i use from wal-mart is 5 mm. i like using it and it saves me from ordering off the net.(dont like to wait!) i have built jets and 3d planes, and a few others out of it. paper is a pain but stick it in the bathroom through a few showers and the humidty will do the rest.

I just fill the tub up and soak it.......make a mess, but its worth it.

most of mine i just round the leading edge, and trailing edge. they fly fine, but more on the motor than the wing.

Question about quality/density of Wally World foam board vrs Depron...

Is it just as good? Or is it worth the cost, and wait to buy the real stuff?

I tried it once and was very frustrated by the paper. Truth is I never did get rid of it completely.

Like the man said, soak in warm water..peel off paper...dry with paper towel and then sand off the remaining paper as much as desired. Works good for me.

Ahhh, I thought I was going for a completely paper-free surface...:o

OK, next time I will fight the Norwegian in me and settle for less then perfect results.

Default That paper is a pain

Just wondering. What if you left the paper on? Wouldn't it add more strength or is it a weight issue?

Probably a dumb question but I assure you it isn't my first.........

I don't think the paper "on" is going to make much of a difference in weight and like you said, it will make for a stronger wing.

I'll be trekking to W/M tomorrow to get me some of that stuff to make a Delta model out of it.

Three ounces savings by removing the paper is quite a bit savings on a small model.

I'll remove the paper before I do anything with it.

Thanks for the tip.

Same here, wow, 3 ounces. That is 25% of what my Eflite Ultimate weighs.

Default get the paper off

did a little building with this stuff, not as stiff as depron but works well, paper is a problem, built an Ultimate bipe but just couldn't balance it at all, way too tail heavy, tore it apart and removed paper, balanced nice and flew pretty good.... do your self a favour, remove the paper and put in a couple of spars, carbon or even bamboo, works well.

Default How to keep the foam FLAT!

I read somewhere that after you remove the paper (I soaked my parts in the tub) that you should lay it on a flat smooth surface. The tension holds the foam parts to it like a magnet if they are wet.

My workbench is formica and it worked out perfectly.

Down with paper!

Thanks for this extra tip. I'll cut a board in half, then remove the paper from one and leave the other one intact. Once the paperless segment is dry, I'll check the difference in weight between the two.

I am sure the paperless one will be lighter, but several ounces reduction by just removing the paper sounds like a lot of weight reduction to me. Even when one considers an entire model made of the stuff.

I also wonder if the reduction won't be offset by the added weight of having to reinforce the paperless foam with carbon fiber rods afterwards.

I'll keep everyone posted.

Depends on the model you are building. I did not use any graphite rod or any reinforcement in my build of the Mini 3DXF. I built a full fuse using formers cut from the Wallyboard and in the front end i used thin plywood for the landing gear and the motor mt.
