i chose 36" wingspan because we have about 3 or 4 different foam wings laying about and wanted to use them the plane will be roughly 32" long, but i could always make a new wing for it, and maybye lengthen the fuse..but i like to keep combat planes short and small and fast...and no this one will not be a spad it will most likely be out of balsa and lite-ply, i made a simler combat plane out of this with an o.s. 25la on it and resempled an old mig fighter, it had a very long nose, and a turtle deck and was quite manuverable, but i had to make the elevator longer because it was doing the heeby-jeebies when i gave it full elevator, it also had a sheeted 36" foam wing..low wing...and was pretty quick..
