O.S. Engine 140RX-P  [OSMG0678]

Huge, 23 cc displacement delivers 3.5 hp, sufficient to put perhaps the biggest pattern airplane through its paces efficiently.

Low-rpm procedure boosts brute energy, producing the opportunity to utilize larger props that creates less sound.

Reinforced beam mount withstands the stresses and vibration as a result of high-g maneuvers.

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

Air conditioning fins stretch through black/silver temperature sink mind through exhaust slot, integrating the cooling capacity that entirely enclosed, superior engines need-and the reliability that competitors need.
