unstable landing

[cromsan]

Once the autopilot is removed upon landing, and regardless of the approximate speed of  80 knots  and a vertical speed down of 400-500 feet, the aircraft  swings a lot. Is it perhaps a problem, in addition to my lack  of skill ,  to adjust the trims and, in this case, how?

So, you're on short final at 80 knots, descending at 400-500 feet per minute?   When you say "swings a lot" are you saying the nose is moving left and right, up and down, or are the wings rocking a lot?  Or all three?  What is the wind?  What kind of controllers are you using (yoke, joystick...rudder pedals?).  Also, have you tried adjusting your control sensitivities?

Make sure yaw damper is off.
