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.

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 favourite 90 size plane and you’ll see what we mean.
