The servo speed function is very useful for scale models with retractable landing gear and gear doors, since 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 is 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.
Please note that servos specified as retract servos have only two stop positions – full up and full down. They
cannot respond to the Servo Slow or Travel Adjust settings. To use the servo slow system with a retracting
undercarriage, standard servos must be used.
Servo speed can also be useful on the Throttle channel. The Throttle servo speed can be slowed so that the engine does not
hesitate or flameout with rapid Throttle stick movement.
There are two speed setting screens, identified by Pos0 and Pos1, referring to any activation switch position. If the speed
setting is to be permanently on, only the figures set for position 0 (Pos0) will be used. Any settings for position 1 (Pos1) will
be ignored. Note that when multiple switches are used to select the Servo Speed values, any switch in the Pos1 position will
cause the Pos1 values to be used.
The channel identification will change according to the selections made in System Mode - DeviceSEL and System Mode -
Wing TYPE. If a channel output has been inhibited or used for the Gyro function, it will not show in the Servo Speed
screen. When dual channels are enabled for any of the primary controls, the channel identification is prefixed with "L" (for
left) or "R" (for right).
To alternate between the POS0 and POS1 screens,
highlight Pos0 (or Pos1) by rotating the Scroll Bar and click on it to
toggle the value between Pos0 and Pos1. When Pos0 shows, the position 0 settings may be adjusted and when Pos1 shows,
the position 1 settings may be adjusted.
To set a servo speed,
highlight the word NORM adjacent to the channel of the servo to be adjusted by rotating the Scroll
Bar and click on it to bring up the sub menu. The figure is surrounded by a box to indicate that it is selected. Rotate the
Scroll Bar to alter the setting. Speeds between NORM (normal speed) and 15 seconds may be set. To return the figures to
the default of NORM, press the clear (CLR) key at the left hand side of the screen. When the required setting is achieved,
click the Scroll Bar to exit the sub menu. Independent speed values may be set for travel each side of neutral. Note that the
arrows at the top of the columns indicate the servo directions.
To select an activation switch,
highlight SW SELECT by rotating the Scroll Bar and click to bring up a browse box of the
available switches. Highlight the required switch by rotating the Scroll Bar and click on it to toggle between position "0"
and position "1". The black indicator square moves between the bottom of the box (POS0) to the top of the box (POS1) to
indicate the current selection. The selection toggles between the POS1 and POS0 positions with each click. When the
required setting is achieved, highlight SELECT and click the Scroll Bar to exit the sub menu.
Please note that FM0
(Flight Mode 0), FM1 (Flight Mode 1) and FM2 (Flight Mode 2) switches will only appear if Flight Modes have
been activated in System Mode - DeviceSEL.
Note that when a switch/Flight Mode is selected to change between the mix values, the switch indicator to the right of
[SRV.Speed] on the top left of the screen changes from "0" (position 0 value) to "1" (position 1 value) as the activation
switch is moved.
