Truck simulation sound kit (SK1)

The Cross RC SK1 is an electronic module that simulates the sound of a diesel engine on a radio-controlled vehicle. The system is synchronized with the throttle control to reproduce different engine speeds: idle, acceleration, cruising, and stop. It is designed for RC trucks, crawlers, and scale vehicles to enhance sound realism.

CROSS-RC Truck simulation sound kit will upgrade to your scale become perfection. It's linkage with accelerator and 100% simulation to sound of truck hooter, running, stop and speed up or down, let you have fun on the scale.
Adaptive Voltage 6-12V (2-3S lithium battery, 6V/7.2V NI-MH battery, 6.6V/9.9V lepidomelane battery are application).
Rated power output 3W, Max. power 9W (suggest to use 2-3W rated power full frequency loudspeaker).

Precautions for use

• Check the polarity of the servo connectors before turning on the power.

• Do not exceed 12 V power supply.

• Use a suitable speaker (4 ohms – 2 to 3 W).

• Avoid exposure to moisture and short circuits.

• Test the module before final installation in the vehicle.
