The Amazing ROTAX AND SLING 2

An aeroplane is a marriage between an airframe and an engine. In fact, a savvy designer begins by selecting an engine that will best give expression to the idea in mind.

WW2 would have been quite different without Rolls Royce’s Merlin. It powered the Spitfire and Hurricane that won the Battle of Britain. It powered the Lancaster that bombed the heart out of Germany by night. It powered the aptly named and wonderfully versatile Mosquito that generally bugged the hell out of them and derivatives powered the P51 Mustang and P38 Lightning that wrestled air superiority from the German fighters by day.
