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 Hangar 9’s Showtime 90 and you’ll see what we mean.
