Hi Steve
When I installed my auto pilot in my Esqual I had the same problem and
my fix was to have a slight down trim applied while in auto pilot . I
still love the Esqual and fly it often.

Adjusting servo gains. Roll is ok but cannot seem to get the aircraft to
stop oscillating in pitch without reducing the servo gain to a very low
value. Can anyone with a GRT system let me know the gain and damping
settings they are using to get me started.

I cannot answer your question but, I am cautiously exploring the
autopilot settings in my new to me Lightning and can forward the
existing settings in my GRT this weekend. I have not activated in
flight so have no idea of how well the gain and damping parameters
perform...

Hello,=C2-=C2-=C2-=C2-=C2-=C2-=C2-=C2-=C2-=C2-=C2- I
am just setting up my GRT autopilot in my Lightning. Adjusting servo gains.
Roll is ok but cannot seem to get the aircraft to stop oscillating in pitc

T system let me know the gain and damping settings they are using to get me
started.ThanksSteve

What aircraft is the GRT in?
When setting up the pitch you really need another set of hands to remove
the effect of gravity on the elevators. Read the test manual carefully.
