The YS-FZ115-S is the newest in the110 Class, 4-strokes.

Many new features include:

The FZ115-S is the same physical size and weight as the YS-110 and produces 10% to 15% more power depending on fuel used. Propellers will normally turn 400 to 600 more rpm on the FZ115-S.  GS R/C recommends prop sizes that allow the engine to turn 8,900 to 9,700 for best results.  GS R/C has been using an APC 15x8 on the CrossFire 320E and Bampf 3D Extreme with outstanding and exhilarating performance in both Sport and 3D flying. Pull ~ 16 pounds of static thrust with a 15 x 8 APC prop.

The lower crankcase has been strengthened for greater rigidity and reliability during both high air and prop loads.  The cylinder is "liner -less" for better heat transfer.

GS R/C has been flying the YS-FZ115-S and evaluating it against other 4/strokes, and the results have been excellent and generally superior to all the other 4-strokes we have evaluated. YS has simply makes the most powerful and greatest valued 4-stroke in its class.

(It replaces the discontinued YS-91FZ and YS-110FZS which are no longer available)

GS R/C recommends the YS FZ-115 S exclusively for the CrossFire and Bampf 3D ARFs.
