The 180hp aircraft is burning £5600 of fuel in a 100 hours, my Rotax will burn about £1600 in the same time. This was the main reason I spent 3 years building my own machine. The figures are ‘absolute’, in that they are based on fuel used and paid for so the aircraft would not have been leaned off in the climb for example. The 180hp Figures are based on 7 pilots over a 4 year period, the Rotax is all me. Expect the fuel costs to more than double in the next three years and again for the next three.
No a 220 hp modern engine would bear about as much resemblance to a Lyk as a modern car does to a vintage Austin. How do I know, because Rotax have designed one!
Bombardier Recreational Products Division has introduced its V220 and V300T aircraft engines. The fuel-injected, watercooled, 120-degree V-6 engine line has a single overhead camshaft and starts with a normally aspirated 220-hp and a turbocharged 300-hp version. A dual redundant electronic engine control unit provides true single-lever control of throttle, prop and mixture setting. Adaptive knock controlling allows the engine to sense the fuel (Avgas or Mogas) and adjust the engine timing accordingly. The engine is geared. Etc etc
