Hey I’m overjoyed to resurrect this old thread! On EOS’s website (eos-engine.com), they announce that their Quattro engine is in production and available as of last month!
I don’t know any other specifics beyond that it’s 276cc and is quoted at “2.2 to 2.8” liters per hour for 30.2 HP, weighing 19.8 kg.
This seems like it could be great competition for Vittorazi’s recently-released EFI-based Moster 185, which boasts similar power consumption but unfortunately relies on a battery good for only 3-5 hours of flight time, and which is not recharged in flight. Previously, my intent to solve the looong XC puzzle was to get an EFI-equipped Moster and attempt to add an alternator/generator to charge its battery, but this EOS engine finally being available is making me think twice. And thrice. Simply being able to not carry a limiting supply of two-stroke oil on long trips would be a major bonus by itself!
I can’t wait to see how it performs.
