Servo: The electro-mechanical device which moves the steering angle or throttle according to commands from the receiver.
The radio device which does the physical work inside the model.
SET: In FailSafe, instruction to receiver to move servos to a preset position if FailSafe activates. See FailSafe. ............17
Skill Level: See Level Selection..........................................................................................................................................12
Slave: Variable in programmable mixing. The channel that follows the master channel. In brake mixing, channel 3 for the
front brakes. See Programmable Mixes................................................................................................................................40
Slop: Unwanted, excessive free movement in a control system. Often caused by a hole in a servo arm or control horn that
is too big for the rod.
SPDR: Speed steering, on return. See Speed Limiter .........................................................................................................23
SPDT: Speed, steering, in turn. See Speed Limiter .............................................................................................................23
SPDT: Throttle servo speed. See Speed Limiter .................................................................................................................23
Speed Limiter: Slows the servo’s overall movement to avoid wheel spin, etc..................................................................23
SRV-VIEW: Servo display (SERVO function) shown on home screen. See System, SERVO. ..................................13, 39
ST-DR: See Steering Dual Rate...........................................................................................................................................38
Steering dual rate (d/r): Adjustable rates of travel to fine-tune the model’s handling. Traditionally, dual rate on a car radio
is used to describe a single rate that can be adjusted while driving. Dual rates on aircraft radios, and on the 3PK, provide
the user 2 separate amounts of travel available at the push of a switch. .............................................................................38
ST-EXP: See Exponential Rate. ..........................................................................................................................................20
STM: Adjustment in ABS. Steering mix setup, controls when the ABS is triggered based upon amount of steering input.
Designed to decrease skidding when vehicle is in a turn, and minimize spin outs. Can be set to off (steering has no effect
on ABS), normal (ABS operates only when steering is turned X% or less) or end (ABS operates only if steering is turned
X% or more). See ABS. .......................................................................................................................................................24
STP: Stop. Timer is stopped. See Timer. .............................................................................................................................30
ST-SPEED: Speed function for steering servo. See Speed Limiter....................................................................................23
ST-TR: Steering trim. See Digital Trims...............................................................................................................................9
Sub-Trim: This is a trim function on many computer radios, allowing fine tuning during set-up, and still allowing the full
regular trim adjustability with the digital trims when in use. Sub-trim adjusts the whole travel of the servo off center;
digital trims just adjust the center toward one end or the other, creating slightly more/less travel for each side...............22
Support and Service: ............................................................................................................................................................4
SW: Switch. In Auto-start means switch only. Auto-start is inhibited and engine cut is now available to be operated from
a switch, which must be assigned in FUNC-SW. See also PS.............................................................................................34
System Settings: Sub-menu which adjusts various system-wide settings including backlighting, buzzer tone, color of LED,
items displayed on home screen, screen contrast.................................................................................................................13
System Timer: See Timer....................................................................................................................................................30
SYSTEM: See System Settings. ..........................................................................................................................................13
Technical Help:......................................................................................................................................................................4
TGP: Trigger Point, sets at what point function will be activated. In ABS, ABS does not respond if less brake is provided
than the trigger point setting. See ABS. ..............................................................................................................................24
TH-ATL (Throttle - Adjustable Throttle Limiter): See ATL. ........................................................................................37
