Team Associated ASC29264 ESS-Air Engine Sound System

The ESS-Air Engine Sound System adds realistic engine audio to electric models, bringing the sound of a running motor to a machine that would otherwise be nearly silent. It is designed for RC aircraft, and the unit has been made lightweight and compact so it can be fitted without adding meaningful weight or taking up scarce space in the airframe.

The output stage is circuit, overload, and thermally protected, so the system guards itself against wiring faults, excessive current draw, and heat build-up during extended use rather than failing outright.

Sound systems are one of the few upgrades that change the whole character of a model rather than just its lap times. The audio rises and falls with your throttle input, so the model reacts to the stick the way a real engine would, and spectators notice immediately. This is an add-on upgrade rather than a replacement part, installed alongside your existing electronics. Consult the included documentation for wiring and mounting details for your particular installation.
