The plane is CloudDancer's update to Mike Stone's Aeronica Chief, although a different panel.Note the reading of 10 = max roll trim applied, yet the horizon remains level!I don't recall any other installed plane here where Cntrl-4 and Cntrl-6 will not engage roll trim. What do I have to modify to add roll trim to a plane? Elevator and rudder do trim properly. Thanks. == WHK ==

The short answer is that the only trim on an Aeronca Chief is a little tab on the left elevator (knob on ceiling of cabin) to compensate for having a passenger.

Well, anyway, I managed to go figure out how to add trim in aircraft.cfg: {airplane_geometry)elevator_up_limit = 30.000elevator_down_limit = 20.000aileron_up_limit = 20.000aileron_down_limit = 15.000rudder_limit = 25.000elevator_trim_limit = 20.000rudder_trim_limit = 25.000aileron_trim_limit = 15.000Due to a serious lack in the ability to realistically simulate human sensory perceptions, feeling the pull of gravity and inertia, seeing 3 dimensional depth, etc., well sometimes cheats that might seem unrealistic, actually might make the experience seem a bit closer to the real thing :) == WHK ==
