Autogyro engine thrust settings
Have not seen this explained and experience has dictated a need.
Thrust offsets: should be known that offsets are most effective
when engine thrust is high and flying speed low. As at take off
and when in hover mode.
Down thrust: my first Giro flew fine with neutral thrust. But, had a trait which was not liked. When applying power to exit a hover
the craft zoomed. It would not exit the hover directly into level flight. 5 deg, down thrust removed that trait without effecting anything else.
Side thrust: There was a tendicy in the hover mode for the Giro to drift left (turn?) Initially right rudder trim corrected that but in turn required left rotor trim for straight flight. Combo trims tend to
be speed sensative, action may change with speed changes.
Remember, thrust is most effective at low speeds?
As Phil has apparently found, about 2 deg. right thrust solved the hover left turn tendicy and allowed the other trims used to go
back to neutral.
Live and learn? Much of that has been with these rotary wings!
