Hovering Pitch (Helicopter) - FUTABA T10J Instruction Manual

The hovering pitch function trims the pitch near
the hovering point.
When the hovering pitch knob is turned
clockwise, the pitch gets stronger and when it is
turned counterclockwise, the pitch gets weaker.
Rotor speed changes due to changes in temperature,
humidity, and other flying conditions can be
trimmed. Adjust for the most stable rotor rotation.
More precise trimming is possible by using
this function together with the hovering throttle
function.
