O.S. Engine 140RX-P  [OSMG0678]

Huge, 23 cc displacement delivers 3.5 hp, enough to put even the largest pattern plane through its paces with ease.

Low-rpm operation boosts brute power, creating the opportunity to use larger props that produce less noise.

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

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

Cooling fins extend from the black/silver heat sink head past the exhaust port, adding the cooling capacity that fully enclosed, high-performance engines need-and the dependability that competitors demand.
