    How did they build a liquid cooled engine that weighs just three pounds more than an air cooled V/W with less horsepower?

    Hummel Engine
    85 hp 94 mm bore x 86 mm stroke 2400 cc 137 to 167 lbs.
    Options- Starter, Alternator, Accessory Case, Aluminum Nicom Cylinders, Dual Ignition

    Well, most of that is Displacement vs. Rip'ems. Monolithic engine block also helps I'm sure.

    The real test is will it be around with spare parts and support in 30 years.

    Well The Suzuki G-motors have been around for 30 years already so, I think the longevity of the platform is as secure as need-be for most. In 30 more years you'll probably still have people in China making replacement parts to keep their fleets of mini-lorries going.

    And even 10 years out of an aero engine that costs $9000 is probably plenty of time to recoup investment so if you're looking at 30 years of service and parts dry up, then that's probably enough blood squoze from the stone.

    It costs quite a bit more than the Hummel engine. But with that horsepower..... might be worth it.

    I noticed recently that Aeromomentum now list a 1.0 3-cylinder option in development. Jeron Smith at Raven Redrives and others have offered these for years, of course, but I like that Aeromentum offers ready-to-run engine of all new parts. Mark Kettering of Aeromomentum says that the 3-cylinder should outperform a big-big bore VW and come in a little lighter and a little more fuel efficient. Suzukiplane doesn't roll off the tongue as easily as Volksplane, but I'll be keeping my eye on that one nonetheless.

    I'm doubtful a non-turbo 1L will outperform a 2.2L engine, even with a gearbox unless you scream the crap out of it. Torsional vibration characteristics on 3 cylinder engines are not very friendly to deal with either. Can be done as Jeron did with a frictional damper but could be challenging. Most of my customers who flew 3 cyl. Suzukis eventually replaced them with 4 cylinder ones and were much happier despite the extra weight.

    Thanks, Ross, I can't say from experience just passing on what I was told. It's not just about the direct drive vs. redrive but also about the larger, slower-turning prop that the redrive can swing. For something like the VP-2 that is already weight-challenged, every little bit helps.

    That sucks... I'm really sorry to hear that. Like so many others on HBA, I was very excited about the Raven 3 cylinder engines as a potential aircraft powerplant.
