The FG-57TS is an updated version of the FG-57T. It has been designed as an alternative yet practical solution to the large singles normally used in 50cc class scale and aerobatic aeroplanes. Being a Saito twin it offers excellent throttle response and lower levels of vibration.
The FG-57TS comes with the standard equipment of Heat Sink, Stand-off mounts (35mm x 4) and lightweight aluminium prop washer. The twin exhaust sound gives a lovely scale-like mellow sound to the exhaust note. Fuel consumption is also very low at just 35cc per minute, making this a cheap engine to run over the long term.
