• No longer marketed by Technobots, these units will remain available from Forge Electronics (the original designer/manufacturer). A new lower profile 3D printed case has been designed but the original functionality remains unchanged.

    A digital synthesized sound unit with 20 petrol/diesel 'voices' - 10 factory presets plus 10 that the user can interactively adjust to better suit the type of model in which it is fitted. Speed demand input may be by the usual RC interface or by potentiometer for use in manually controlled vehicles like the Toylander childrens electric vehicles for example.

    Toylander builders should note that they need to supply a seperate 5v supply to run the electronics and that the 12v speaker supply may be derived from tapping off the lower 12v battery in the 24v drive system. In addition the signal connectors are standard RC types and thus the supplied short RC cables will require lengthening to suit.

    Please state when ordering if you require the RC or Potentiometer controlled version so that the appropriate printed instructions can be supplied and the unit can be dispatched with this configuration preset.
