just a ?
 
hey everyone,just a ? about size and munuverability.if you had any airplane that did not knife edge well and added lenght to it and not height would it knife edge better?like a 60 size plane with a 38" lenght and 3 1/2 '' high,making it longer by say 10''.

The increased length will give more rudder power but unless there is lifting area on the fuselage up front it won't help much. Notice most modern pattern airplanes have a lot of area forward of the trailing edge of the wing. This gives them lift in knife edge. Adding fuselage height with a light foam block (streamlined of course) would be a quick test of whether or not the extra fuselage height would work.

Roger that girlfriend.....more area from the (rear of) the wing forward. I've used big, nearly flat "canopies" for this purpose. More effective than just adding length.
