They are very good and work well not a spike in sight.
However before take off move your stick to the limits and hold for a few seconds.
Every time you start the game your elevators and aelerons deflect very slowly on first use, but once the limits have been found its back to normal instantaneous response.
If you can afford it go for the throttle option as well, like many others mine has been playing up (not getting to max or min at times) which prevents wep kicking in or being able to stop on runways unless you kill the motor.
