Rotax 915 climb to 30,000

[Thruster88]

Very impressive what this little engine can do, more grunt than a 180hp 360ci(5.9litre) lycoming above 8000 feet.

A supercharger on "anything" makes it better at altitude. Geoffrey De Havilland made around FL240 with an upright de Havilland motor of less than 130 HP about 1923. in a Gypsy Moth. Nev
