The Throttle Trim Lever 19 affects the servo po-

sition only when the throttle control stick is in the

LOW (IDLE) position. HIGH throttle position

remains unchanged. Adjustment of the throttle

linkage is therefore very convenient.

Use a servo horn that allows slightly more

throw than needed.

Set the maximum opening at

HIGH throttle

using Memory ATV (Page 18).

Use Memory ATV to set the extreme LOW

position to prevent servo binding when the

throttle

barrel closes

against

the

idle

stop

screw.

With the engine running, use ATL Throttle

Trim Lever 19 to set the optimum idle

speed.

FS FUNCTION/HOLD FUNCTION

Fail Safe (FS) is a function which moves the servo

of each channel to a position preset (at the trans-

mitter) when an erroneous signal or continuous

strong noise is received for about 1 second or

longer. When the proper signal is lost or strong

interference received, the airborne system will

operate in the HOLD mode for about 1 second

before switching to the FS mode. When a normal

signal is received again for about 1 second, FS is

released and normal control resumes.

The HOLD functionstops all servos selected (by

button [47] at

the position just before noise or

interference was received. When a normal signal is

resumed, HOLD is released.

A combination of FS and HOLD functions can be

selected on each channel at the modeler's discre-

tion.

FS, HOLD, and SERVO TEST functions are oper-

ated using three switches on the trimmer panel.
