Affordaplane is one of the simplest in construction ultralight Part 103 airplanes. It's a fixed0wing aircraft weigting 254 pounds.

Presumingly this is the official site where you can buy complete building plans for only $4.95.

A couple of facts to note:

  • It's known also as A-Plane so when you see it on a forum or website, have in mind they talk about the same thing.
  • Due to the simple construction is't easy to build even from first-time builders.

Estimated cost for building this airplane without engine and tools is only $2,000! (more info here) So it well deserves its name.
