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.
