Like my club for example. You got most of the guys flying their balsa sport planes, a few with some more scale planes, the one guy with the jet and the big planes, and some other guy flying his massive 3D Foamie. And then me with the occasional RTF foamie and foamboard plane.
Anyway back to the weight of foamboard. Down here in australia, the only foam we have access too, is super heavy, super expensive, and you can buy it in bulk. For a plane like a
FT tutor, you would be paying for about 10(!) times the price of the foam.

And we also have to deal with the weight, which is probably 2-3 times heavier than your DTFB.
I have resorted to buying foamboard from amazon. At this point I really don't care about the weight, but the price and shipping cost. ATM I am looking for alternatives, because getting foam in A1 sheets has an ENORMOUS shipping cost, like Coreflute, which is heavy, but super strong, and hotwiring airframes too. So far however, I still haven't managed to find a good alternative.
(yes i have tried FTFB, which is super nice, but costs like $80 to get it into the country)
Anyway that is my rant done, if anyone can suggest any alternatives, I am open to suggestions.
