I just checked in the attic, I have a New-in-box WH Edge 540, but in the manual it's called a 28%, not 30%, and the wingspan is listed as 84", not 88". Earlier model? It's listed as a 50cc plane, the manual calls for 50cc or 62cc. I believe I ordered it in 2002. (Edit: Nope, 2004) As I recall, they offered an upgrade hardware set, wing tubes too if I recall correctly, and I got the upgrade too.
