I have a KFC-200 with FD as well. When it's gusty it does seem a little slow
on the response, and hunts a little. With smooth or constant winds it tracks
a glideslope like it's on rails.

It used to hunt a little in pitch, and I needed the cables tightened a
little, which seemed to help.

GPS approaches (LNAV/VNAV and LPV) are even smoother, but I've had some
issues capturing the GS with the KFC-200
