Does anyone know this engine?
ParaToys & BlackHawk Powered Paragliders, Paramotors, Parapente
Their PPG is powered by an industrial Generator Engine...conversions of which have been catching on, but seem heavy. I don't see a mention of weight in their spread.
I don't know if they started with a standard Generac or what, but they describe "four-stroke engine dual high energy ignition. air cooled, oil cooled with 38 HP, 60 lbs torque at 3500 RPMS." And they can fire it on Propane.
They're claiming " an engine that produces more thrust than a Rotax 447, the same thrust as a Rotax 503 or 582 with the same propeller and re-drive at half the RPMs...can deliver up to a 75% increase in fuel efficiency versus 2-stroke engines. It is 67% more efficient on propane which will net you an average 4 hours flight on Propane and 4.5 hours on our Gas Version. By using propane and a 4-stroke engine at low RPMs there is an estimated 3000+ hours between rebuilds or TBOs. This is 10 times less maintenance than any Rotax."
Too good to be true, or does that compare well with Valley's Big twin?
I've hung out at the small 4-stroke Yahoo group site, but not sure I'd want to tackle my own conversion...
