A couple guys have suggested I should include these in my blog, so I'm adding the latest bit of foamie madness from Armada: One Sheet planes. This all started over a year ago, when one of the RCG members proposed a challenge to design and build planes from a single sheet of Dollar Store Foam (20" x 30"). The challenge proposed classes for speed, heavy lift, duration, etc. Unfortunately it never really got going, but the wife and I happened to be on vacation in Texas when I first read it, and during the extended travel times driving around TX and on way home, I figured out how to make the One Sheet Glider (OSG) entirely out of a single sheet. Worked up the design in Sketchup, printed tiled plans and put one together. She flew quite nicely with original KFM5a wing in light air, and thermalled pretty well. Further tinkering resulted in a Version2 with KFM3 wing and it was even better. Build thread is here: https://www.rcgroups.com/forums/show...&highlight=osg

Having done the OSG using the entire sheet, with only tiny slivers of scraps, I was hooked on the idea of "how many plane types could be made using up an entire sheet?" That led eventually to the One Sheet Bipe (OSB). Build thread here: https://www.rcgroups.com/forums/show....php?t=1368918 . This one doesn't use the sheet quite as efficiently, the scraps are a bit larger, but It's still pretty efficient use of the space available. It's gone through two versions, and I have to say the...Continue Reading
