With advances in microcontrollers and some clever programming, we have managed to squeeze the Diesel, Petrol and Steam sounds all into a single unit - the Combo. As with all of our sound units, it is designed to be used with any standard radio control system (1-2mS).
There are other enhancements in the Combo version over the individual sound units, 3803-210,211 & 212.
NEW FEATURES- Petrol, Steam and Diesel sounds in a single module (only 1 available at any one time of course)
- Smoother, more linear throttle response
- Tickover and top speed optimized for each selected cylinder count
- Improved stability of idle timeout duration over the range of cylinder counts
- Improved Diesel sound
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.

The Diesel sound in the Combo is actually an improved version of the combo, we will put a sound recording of this up as soon as we can.
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, Petrol or Steam selectable using a link inside and a simple set-up routine.
Number of cylinders: (link selection procedure) - Diesel 2, 3, 4, 5 or 6
- Petrol 2, 3, 4, 5 or 6
- Steam 1, 2, 3, 4, 5 or 6
- Engine stop / start: Automatic, determined by throttle demand and idling period
