Assembly Instructions

Follow these steps carefully for the initial setup and assembly of your RMX 2.0 RTR.

STEP 1: Pasting Sponge & Electronic Setting

This step involves applying shock-absorbing foam and setting up the electronics. Ensure the following operations are performed before assembling the main parts package:

1. Install transmitter batteries.
2. Loosen the receiver antenna.
3. Connect the ESC (Electronic Speed Controller) and battery.
4. Switch on the transmitter.
5. Switch on the ESC.
6. Allow the car to stand for approximately 3 seconds until the front wheels turn once in either direction.
7. To complete the boot process, individually turn the steering left and right to their full extent.

Note: The default settings are pre-configured by the factory. The RMX 2.0 RTR electronics (Transceiver set, ESC, Gyro) are ready for use after battery connection. Refer to specific instructions for adjustments.

⚠️ Please use this product in a safe, open area.

STEP 2: Attaching Battery

Connect the car battery to the ESC. The battery installation method and conservation may vary by battery specification. Recommended battery dimensions are L140mm × W48mm × H25.4mm (maximum).

▶️ Connect to battery!

⚠️ After all settings are finished, please use the product in a safe place. Before use, turn on the transmitter first, then the car. Turn off in reverse order.

STEP 3: Attaching Body Mount

Adjust the body mount height according to the car's body shell for proper fitment.
