Use for cockpit controls (trim, yoke, etc). Use [control-surfaces] for the surfaces that actually move.

What could be the cause of an uncommanded roll at high speed?
If this were a model aircraft with a wide speed range (like, say, a hand launch glider), I'd expect this to be a cross-trim problem. Generally, the rudder will have more authority at lower speeds, wh …

Why not use the yoke to control yaw, as well as pitch and roll?
The modern control yoke is directly derived from the "joystick" control that became standard on aircraft in the days when Glenn Curtiss personally ran the company that was the main competitor to the W …

Can aileron differential eliminate adverse yaw?
Based on my experience (seeing, not flying) with radio control models, no, not completely. I have seen "drag buckets" added to ailerons, as well as coupled spoilers, which can come close, but there a …

Light aircraft elevator/aileron/direction not working
If a major flight control surface fails in flight, you'll be lucky if the ballistic parachute can save you. An aileron, for instance, that goes "hard over", will put even the most docile training air …

What is the purpose of attaching a flat plate to the rudder trailing edge?
What seems be the case here is that a truncated trailing edge has a flat plate riveted on (called a double Gurney flap). This places the plate perpendicular to airflow (more or less). This, in turn, …

What would be involved in disconnecting one set of controls in an aircraft?
Many tandem two-seaters have an easily detached rear (or in some cases front) control stick. Combine this with a simple rudder pedal cover, and a passenger is locked out of all controls other than th …

How does a circulation control helicopter work
A quick scan of the linked document suggests that they're referring to controlling the relative amount of engine exhaust directed into each rotor, which (due to the downward direction of the exhaust j …

Is it possible to stall a plane so badly that the nose refuses to go down due to lack of air...
What you describe is a tailslide, as another answer has noted -- but there is a condition in which the wing is stalled and the normal recovery method (apply down elevator and wait for the nose to drop …

Why doesn't the A-4 Skyhawk require rudder in coordinated turns like on other Century Series...
Based on the included quote, this probably because of the effectiveness of rudder control on the A-4. If it's effective enough at low speed to control against a high crosswind component for takeoff o …

Why do the ailerons of this flying wing work oppositely compared to those of an airplane?
Most likely the adverse yaw effect (due to the induced drag of the increased lift on the down-aileron side) is causing the wing to yaw the opposite direction from the intended roll, and the yaw causes …
