AAC construction for lighter weight and increased longevity
Saito's FA-180 engine is fast becoming the pilots choice for powering 1.20 size airplanes. The FA-180 offers a 20% displacement increase over the popular Saito FA-150. What does this mean? How about a 8% power increase over the FA-150 and an awesome 14% power increase over the FA-120. And what’s more the FA-180 fits in the 1.20 size mount. So if your old 1.20 just doesn’t have what it takes, replacing it with the Saito FA-180 is no problem. Simply put the FA-180 is the most powerful in its class.
Saito’s 1.8 cu. in. four-stroke, the FA-180, is based on their popular and powerful FA-150. The new FA-180 is the largest displacement four-stroke single that will fit popular 1.20 size aircraft. The FA-180 has the same mounting dimensions and mounting hole-to-prop washer length as their 1.20 and 1.50 with only the head and valve covers being slightly raised an additional 2mm, so it will mount right in most 1.20 size airplane applications. At 31 ounces, the total weight of the 180 is just an ounce more than Saito’s 150 with mufflers.
To achieve the additional 20% displacement, Saito has increased both the stroke 1mm (to 28.6mms) and the bore 2mm (to 36mm) over the 1.50. To feed this overgrown giant, the carb bore has been increased to 12mm and the internal openings in the exhaust have been enlarged considerably for freer breathing. And, like other Saito engines, the 180 is available in the standard natural finish or as a GK (Golden Knight) version with a high gloss black case and gold valve covers.
