SuperFly -- my first plane after earning my wings with the ubiquitous Champ trainer. Still fly it.

Amazingly, you can still buy it too. Cheap.

UCreate 10 pk 20''x30'' Foam Boards-Assorted at Joann


Hi,

I think $Tree foamboard is the way to go, but I looked into the UCreate foam a bit ...

Found a 10 pack of 20"x30" at Joann's, but it's expensive
https://www.joann.com/ucreate-10-pk-.../16741142.html

Walmart has
15"x 20" in white for $1.77
https://www.walmart.com/ip/UCreate-F...-Each/21652305

22"x 28" in black for $0.67
https://www.walmart.com/ip/UCreate-F...Sheet/17203968

Mfg website for 15"x20" white

Amazon white 20"x30", 10 sheets, $25

I suspect there's more to it than just finding that brand. There could be multiple U-Create foamboard products and they might differ significantly.

As an example, if one just reads the descriptions, Adams Readiboard (Dollar Tree) sounds similar to Elmer's Posterboard (WalMart). But I use both and they are very different in density and weight. I have to design specifically for each because they're not interchangeable.

I don't know how you can choose a posterboard without actually buying it and doing your own tests and measurements.

FWIW
Readiboard = .19g/sq-in
Elmer's = .38 g/sq-in
U-Create = ???

When I tried that, with shipping and tax, that came up to $73.54 for 10 sheets of 20x30 of 3/16" (4.7mm) material

Last month, for $95.46 including shipping, I got 16 sheets of Grade A and 8 sheets of Grade B 24x48 1/4" (6mm) Model Plane Foam from Springer. For $22 more than the JoAnn price, I got over 4x the material (in total square inches). Although I haven't yet begun to build with it, I am very impressed with the quality of what I got from MPF/Springer.

Too bad our dollar is in the dump against the almighty Yankee buck and that shipping costs are 'out of sight' to go north past the 49th.

While one can argue that many foams might be superior, I haven't found anything that justifies a huge cost increase over Dollar Tree Foam. Here's my latest delta using a single ply of DTF even though it's a 1000mm wingspan. But it does use a carbon exoskeleton.

And yes GG, this IS an equilateral triangle. Three 1m carbon tubes secured by a heavy cord for a bulletproof triangular frame.

But, it doesn't quite cut the mustard for some reason. Probably that extra ounce.

So, choppin' out a 'Superflea type' platform in the cheap light stuff.

Going to increase the power, ESC and change the servos to 5 gram. It's a great flyer but lacks vertical gusto.
