The diesel engine sound unit is designed to be used with any standard radio control system (1-2mS).

The unit is easily installed by removing the ESC lead from your receiver and plugging in a lead from the sound unit in its place. The ESC lead then plugs into the sound unit, thereby obviating the need for a Y lead.

The unit's electronics take its power from the receiver, but the loudspeaker derives it power from either the model's main propulsion battery or a separate battery pack. Connections for the speaker power and the loudspeaker itself are made using screw terminal blocks.

The neutral state being indicated by a case mounted LED to assist setting transmitter throttle trim.

Specifications

Contents: Assembled and tested engine sound unit, pre-crimped wires and housing to make up a 150mm lead to connect to the RC receiver, full colour instruction booklet.

Size: 80 x 40 x 20mm

Speed demand sensing method: Receiver throttle channel (unit has pass-through to ESC)

Neutral (idling) signal condition: 1.5mSec

Receiver voltage (which powers the unit's electronics): 4.8v min to 6v max (this is usually supplied by a BEC which is often incorporated in the ESC)
DO NOT USE A "6V" LEAD ACID BATTERY - a fresh fully charged one of these can output as much as 6.6v

Speaker impedance: 8 ohm minimum (Technobots part no. 2400-015 recommended)

Speaker supply voltage: From zero to 12v (governs the volume of the unit)

Audio power output: Approx 4W RMS @ 12v into 8 ohms (equates to 160W PMPO in today's modern hi-fi advertising terms!)

Engine type: Diesel

Number of cylinders: Diesel 2, 3, 4, 5 or 6 (link selection procedure)

Engine stop / start: Automatic, determined by throttle demand and idling period
