O.S. Engine 140RX-P  [OSMG0678]

Huge, 23 cc displacement delivers 3.5 hp, enough to place even the largest pattern airplane through its paces effortlessly.

Low-rpm procedure boosts brute energy, creating the opportunity to use bigger props that create less sound.

Reinforced beam mount withstands the stresses and vibration due to high-g maneuvers.

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

Cooling fins stretch through the black/silver temperature sink head through the exhaust slot, incorporating the cooling capacity that completely enclosed, superior engines need-and the reliability that competitors need.
