Operating Instructions

1. Powering On

  1. Turn on the transmitter first.
  2. Then, turn on the vehicle's power switch. The ESC will emit a tone indicating it's ready.

2. Basic Controls

  • Throttle Trigger: Pull to accelerate forward, push to brake/reverse.
  • Steering Wheel: Turn left to steer left, turn right to steer right.

3. Advanced Features

  • Remote-Locking Differentials: The TRX-4 Defender features remote-locking front and rear differentials. Use the designated switch on your transmitter to engage or disengage the differential locks. Locking differentials provide maximum traction in challenging terrain.
  • High/Low Range Transmission: Switch between high-speed and low-speed gears using the dedicated switch on your transmitter. Low range is ideal for technical crawling and steep climbs, while high range is suitable for faster trail driving.
