Meet the Saito FA-125A engine, a compact 1.25 cubic inch powerplant designed to fit into a 1.00-size airframe. It’s lighter and more powerful than the FA-120 it replaces, delivering stronger thrust while saving about 10 ounces in weight. It can turn an APC 16x6 prop at around 9,000 rpm and uses 13 mm muffler threads for straightforward exhaust mounting. Designed for a broad range of models—from .90-size sport aerobats to 1.20-size sport and IMAC aircraft—the FA-125A brings impressive power in a small footprint. Available in the Golden Knight edition with a gloss black finish and gold-plated valve covers for a premium look, it pairs well with a 16x6 prop and mufflers with 13 mm threads, making installation in many popular airframes quick and clean.
