Functions & Settings

Trim Adjustment

• Steering Trim (ST.TRIM): Adjusts 1CH steering centre for straight tracking.
• Throttle Trim (TH.TRIM): Adjusts 2CH neutral throttle position.
• Adjustment Range: -60 to +60, with audible beep at neutral and endpoints.
• Steering Dual Rate (ST.D/R)

Controls maximum steering servo travel.
Adjustment range: 0% – 120%, default 100%.

End Point Adjustment (EPA)

Limits servo travel per channel.
Range: 0% – 120%, default 100%.

Throttle Hold (Idle-Up)

Applies preset throttle at neutral. Adjustable 0–100% (linear scale).
Use for engine warm-up, not while driving.

Channel Reverse

Reverses servo direction on any channel.

Steering & Throttle Curves

Adjust servo sensitivity across travel range.
Positive = sharper initial response.
Negative = smoother initial response.
ABS Braking

Pulse braking for smoother deceleration and straight tracking.
Parameters include:

PT (Activation point)
WD (Brake pulse distance)
CY (Pulse speed)
DT (Brake release delay)
Model Memory

Store up to 6 model profiles, each with unique binding and settings.

Channel Mixing

Supports combinations: 2CH/3CH, 2CH/4CH, 3CH/4CH for advanced setups.

Timer

Count-up or countdown modes with audible alarm.

Telemetry

Displays TX/RX voltage and warns of low-voltage conditions (<4.6V for 3+ seconds).

Reset Function

Restores factory defaults (erases all model memories).

Sound Control

Toggle audible tones, alarms, and timers ON/OFF.

Channel Monitor

Displays real-time servo pulse values (approx. 1000–2000µs).

Digital 4CH

Optional 4th channel, usable in mixed or proportional mode.
Can be paired with 2CH or 3CH for advanced mixed control.
