The name "Flatouts" is a product line from Great Planes. There are other companies that make flat foamies, and I'm sure some make an Edge 540, but the name Flatouts is a Great Planes product name.

Do you have any pictures of what it looked like? Was it actually a flat foam plane? Also, FYI, Electrifly is Great Planes' electric product line/brand. Do you remember where you purchased it (LHS, online store, etc.)?
