If you apply full force on the pedal at maneuvering speed how much sideslip angle's you get ?I read on forum topic you get really low deflections some 5-- 6 degrees.But those angles are enough to sweeping the nose for aiming someone who jerks his plane in front of you?

I guess (do not know for sure) this depends fully on the forward airspeed of the plane:
- Lower forward airspeed, greater yaw
- Higher airspeed, lesser yaw

This document - about the F16 FLCS - is filled with diagrams and schematics:

This is NASA Technical paper 1538 (Dec 1979, 233 pages pdf) about
"Simulator Study of Stall/Post- Stall Characteristics of a Fighter Airplane With Relaxed Longitudinal Static Stability"
also contains lots of technical information about the F16 fly-by-wire-system:
