O.S. Engine 140RX-P   [OSMG0678]

Huge, 23 cc displacement delivers 3.5 hp, enough to put perhaps the biggest pattern plane through its paces easily.

Low-rpm procedure boosts brute power, producing the chance to utilize bigger props that create less noise.

Reinforced beam mount withstands the stresses and vibration brought on by high-g maneuvers.

One-piece crankcase offers greater durability, plus external webbing at high-stress places for security against heat-generated distortion.

Cooling fins extend through the black/silver temperature sink head after dark exhaust port, adding the air conditioning capability that completely enclosed, superior machines need-and the dependability that competitors need.
