On a flapless plane, does the aspect ratio of the elevator make a difference, or is it just the total area of the elevator that matters at any given angle of deflection (holding the fuselage length constant)? I'm thinking of desensitizing an oversensitive plane with an excessively large elevator without reducing the total tail volume by cutting the elevator longitudinally (without removing it) into 3 sections: a larger central section of functioning low A/R elevator and two smaller "tips" which will be made fixed.
This will allow me to bring the elevator deflection up into the range I prefer: 25 to 35 degrees. There may not be anything technically wrong with having very little deflection on a large elevator, I just prefer what seems to me like a "normal" range.
Thanks
