The Twin Oscillator is a new model developed from the recently revived S.T. Oscillator. The main advantage of the Twin Oscillator over the single apart from the greater power, is that the engine comes complete with reverse gear. This double acting engine has proven itself to be very powerful for it’s size in our bench tests & has already attracted a great deal of attention at the exhibitions we have shown it.
