F3A Biplanes have a future!

[Jeff Hughes]

Well, there's no reason a biplane can't be made where the both wings 
come off and store as one assembly and slip over the tail. A couple of 
bolts on the bottom and one for the center strut....




> The only snag that I have found with bi-planes is the assembly at 
the field! Four ailerons?  wing struts? etc. I sold a very good flying 
Ultimate and the 16 screws it took to assemble! I prefer one wing 
screw and two aileron leads ....Hmmmmm.... can I adapt???
