Question

To maneuver the fighter is better to have two tail stabilizer (SU-35(Russia)) or one(F-16)?

Answer 1

Dear @Vladislav,
The Sukhoi-35 is much more maneuverable than the F-16 due to its dual rudder configuration.

Answer 2

Depends, As planes go faster they need bigger tails, Bigger planes also need bigger tails. having twin tails gives you the same area of tail surface in less height. The tail are also sized to allow for control of an airplane if an engine fails, many twin engine fighter also have twin tails. Also at high angle of attack a centered vertical tail can be largely block out of airflow by the body of the airplane, twin tails particularly when canted outwards can keep the tail in moving air. Finally stealth planes try to avoid having right angles that will reflect radar back in the direction of the attacker. Single tails have to be vertical, so stealth planes tend towards twin tails, that are canted off vertical.
Aerodynamics is a very complicated subject (of which I am an amateur), but in general when there are multiple reasons and trade-offs for a design element, choosing just one reason for why a choice was made, is likely a disservice for understand the complexity of the design.

Answer 3

Don't forget that the more mass you add the harder it is to change your inertia and therfore the harder it would be to maneuver. So it probably has to do with how much surface area to weight ratio you are getting as to how much the tail configuration is adding to your maneuverability.

Answer 4

But there are so many factors...

Answer 5

I have a personal experience with the Su-35 and the F-16 and find the Su-35 much more maneuverable . Dual rudder configurations are better than a single rudder because you are able to have a larger yaw. Single ruddered airplane, the F-16 is no doubt maneuverable but it relies heavily on fly-by wire control.
