On what kind of flying you like to do. A Stick is a Stick is a Stick.
They have their strengths and weaknesses. I had one with a 1.35 and then a 1.60 on it. It had the quad flap set up. After reading what others were doing with theirs as far as elevators and harrier type stuff I became frustrated with mine and sold it. No matter what I did, it just wouldn't perform the way the book said or others were describing. A Cap is in a different category. It's a more precise aircraft with a different set of rules. That's the kind if flying I like. Maybe one of the aerodynamic gurus can explain why, but I wouldn't put the quad flap setup on a cap.
Maybe throw in some switched reflex or airbrake if needed but that's it_Bob
