You pretty much figured it all out with the four numbers, correct.
Between WW1 and just before WW2 you have the Golden Years of flight when the world was learning how to build A great airplane and not just Bipes. There were some strange flying machines during those years, some worked and some didn't.
The point is these are the years to be searching if you want to see the great classics. By the way, the Waco's are not only one of the best looking Bipes to ever fly, they are great in the air and wonderful stunt planes too. Just way too many great Bipes to even come up with A list though.
WW2 sort of put an end to the two wings except for post war stunt Bipes like the Pitts and several others used to compete with.
As RC pilots most of us go through A Bipe stage. Mine lasted for several years. Almost everyone loves A Bipe but because of the extra wing and work setting one up you don't see A lot of them at clubs. When you do they draw A crowd.
Just make sure you have A GOOD incidence meter before you build one, that's about the only real extra work involved and the key to A good flying plane.
Good luck!!
