  • FA-125A AAC with Muffler: AG

    Only Saito could put 1.25 cubic inches of power into a 1.00-size case. Not only is the FA-125 lighter and more powerful than the FA-120 it replaces, its unique size allows modelers to apply its awesome power to a wide variety of airplane sizes. It will work with anything from .90-size sport aerobats all the way up to 1.20-size sport and IMAC planes. As with most Saito engines, the FA-125A is available in a stunning Golden Knight version with a gloss black finish and gold-plated valve covers.

    With 10 fewer ounces and .05 more cubic inches than the FA-120 it replaces, the FA-125A gives new meaning to the term “escape velocity.” Just bolt one to the nose of Hangar 9’s ShowTime™ 90 and you’ll see what we mean.


    • Less weight but more thrust
    • 10 ounces lighter than the FA-120
    • Turns an APC 16x6 at 9,000 rpm
    • 13mm Muffler threads
