The carbon fiber engine cowling was a structural component of the aircraft and as such had to be protected from heat-soak after shutdown. This was accomplished via two 2-stroke weed blowers immediately after the blades stopped turning, quickly followed by two air conditioner blowers attached to the air inlet "scuppers".
Two-stroke model engines, most often designed since 1970 with Schnuerle porting for best performance, range in typical size from .12 cubic inches (2 cubic centimeters) to 1.2 ci (19.6 cc) and generate between .5 horsepower (370 watts) to 5 hp (3.7 kW), can get as small as .010 ci (.16 cc) and as large as 3-4 ci (49–66 cc).

Animation of a two-stroke engine. A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft in contrast to a four-stroke engine which requires four strokes of the piston in two crankshaft revolutions to complete a power cycle.
Packard DR-980 diesel radial aircraft engine A Nordberg Manufacturing Company two-stroke diesel radial engine for power generation and pump drive purposes. While most radial engines have been produced for gasoline, there have been diesel radial engines. Two major advantages favour diesel engines — lower fuel consumption and reduced fire risk.
The result was the Space Bug .049 Contest engine, Cox's first model plane engine which was completed in October 1951. [8] In 1952 the first name change was made to L.M. Cox Manufacturing Company Inc. The Space Bug engine set the scene for all the Cox engines that followed, and went into full production in 1952.
A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...
The Rolls-Royce Crecy was a British experimental two-stroke, 90-degree, V12, liquid-cooled aero-engine of 1,593.4 cu.in (26.11 L) capacity, featuring sleeve valves and direct petrol injection.
