The Airplanes Database, many airplanes class on this database, but I don't know if this quite accurate to define these classes as a class. Currently there is: giant, park flyer, glider, micro, pattern flyer, sail plane, scale planes, soaring, sport flyer, and warbird. Personally I have zero experience on airplanes, these field I gather by searching on internet. I found many great forums and learn from them, I'm blind not exposed by this hobby. We really needs flyboy on board, help us to improve this airplanes database.
