SRV. SPEED – SERVO SPEED
The XP9303 system provides the ability to adjust the speed of servos on each channel in both
directions. The speed may be adjusted downward (servo slowed-down) from its normal speed
but it cannot cause a servo to move faster than its rated specifications. Furthermore, each servo
can have a separate speed in each direction that is Flight Mode or switch selectable.
Two sets of servo speeds are possible – one set is associated with Pos0 and the other set with
Pos1. A Flight Mode or switch may be used to select between the two sets of servo speeds.
The servo speed function is very useful for scale models with retractable landing gear and gear
doors as in many instances the need for gear door sequencers can be eliminated. If the gear door
servos move at normal speed and the landing gear servos move at a slower speed when the gear
are lowered, the gear doors will be open before the landing gear begins to come down. In the
opposite direction, if the gear door servos move slowly and the landing gear servos move at
normal speed, the gear can retract before the gear doors begin to close.
Servo speed can also be useful on the throttle channel. The throttle servo can be slowed-down
such that the engine will not flameout because the carburetor is opened or closed too quickly
when the throttle stick is jammed from low to high and vise versa.
To adjust servo speed, highlight and select SRV. Speed in the FUNCTION List.
