Fit, torque and sound from the FS-200S-P Surpass

The FS-200S-P Surpass packs four-stroke performance into the same chassis area as the FS-120S-P while boosting torque and throttle response. Its compact layout makes it an attractive upgrade for pilots who want more punch without big installation changes.

Balanced performance for different flying styles

Sport flyers will notice improved climb and acceleration, while scale enthusiasts will value the engine's realistic exhaust timbre and smooth running. The supplied F-6010 muffler can be rotated through 360 degrees to suit different cowling and tailpipe arrangements.

Smart design for easier installation and fuel delivery

Features such as a reversible carburetor and a narrowed cam housing make mounting more flexible. The PD-08 diaphragm pump delivers steady fuel feed even under unusual attitudes, and the bigger carb intake helps the FS-200S-P achieve higher power than the FS-120S-P.

The FS-200S-P suits pilots who need straightforward installation with a clear increase in torque and authentic four-stroke sound for scale fidelity.

Which airframes take the FS-200S-P easily?

Any model that accepts engines in the same mounting footprint as the FS-120S-P can usually accept the FS-200S-P with minimal modification, though cowl clearance and propeller choice should be checked first.

Do I need a special glow plug or fuel?

The engine ships with a type "F" glow plug. Standard nitro fuels appropriate for four-stroke RC engines are recommended; follow the engine manual for suggested fuel nitro content and oil ratios.

How significant is the power increase over the FS-120S-P?

Thanks to the larger carb intake and intake port, the FS-200S-P delivers roughly a 43 percent power uplift compared with the FS-120S-P, which translates to stronger climb and cruise performance in many models.
