Don't laugh too hard, there are Pizza Box planes out there with fuelproofed cardboard, as well as the coroplast ones, for a wing you know... And as soon as HOOTER springs for some junk high torque servos, I'll build my flying ladder!

Imagine an 8 foot section of cheap aluminum extension ladder (9 pounds). Attach two 4" by 8" sheets of 2 mil coroplast with internal foam ribs and 2 wing tubes through the ladder rungs for wings, build up a coroplast tail and faux fuselage. Then... (drum roll please) put on the four 31cc Ryobi gas engines that I have! I've got everything I need but servos and coroplast. Best of all, I have zero dollars invested so far! And I don't plan on buying anything but the coro... It ought to be fun anyway...
