    Some of you may have heard of the little Savoia S42A engine, a little 600cc four-stroke boxer.
    Apparently the company had stopped development of that engine, but have started a new 800cc V-twin conversion (four valves, per cylinder, EFI, etc).
    No word on if/when it will go into production, but at $7500, it's not a bad deal, though probably expensive for the budget builders (though possibly much lighter than a VW?

    I've attached the info brochure. Info below:

    [FONT=Verdana, serif]** V-Twin, 4 stroke, radiator watercooled, OHC, 4 valve per cylinder , DDI ignition, dry sump[/FONT]
    • 800 cc displacement, 10:1 compression
    • [FONT=Verdana, serif]fuel injection with programmable ECU, altimetric mixture compensation [/FONT]
    • [FONT=Verdana, serif]12V electric start and 10A PMG alternator[/FONT]
    • [FONT=Verdana, serif]Max Power: 60 HP (44 kw) at 6000 rpm[/FONT]
    • [FONT=Verdana, serif]Torque 73 Nm from 4000 to 5000 rpm[/FONT]
    • [FONT=Verdana, serif]95 octane gasoline consumption (min.):265 g/kw.h [/FONT]
    • [FONT=Verdana, serif]Pulley & belt reductor gear, freewheel, CCW turning, 2.043 /2.65/ 3:1 ratios[/FONT]
    • [FONT=Verdana, serif]Total weight with PRSU: 57-59 kg[/FONT]
    • [FONT=Verdana, serif]500 h TBO[/FONT]**

    Why would anybody consider an unknown quantity that includes a low and expensive TBO.

    I'm just posting the info - making no judgements about the engine or the company (after all, we're developing our own engine packages).

    Does anyone recognize the base engine?
    I would love to find out what it is - it is probably a small production car out of South America, or imported there from Asia?
    I like the concept... interesting they don't even show the redrive side.

    Am I right in calculating that to be 4.28 US gph at full power? So 3.5 US gph at cruise? That doesn't seem great.

    Still, there isn't a great deal of choice below 80HP and the price isn't too horrible.

    Other than weight, I don't really see any advantage here over a VW conversion. And the weight advantage isn't THAT big. Until this gets more track record, I'd be far more likely to stick to "tried and true".

    I don't doubt your figures, I just have no way to corroborate them.

    Yes, it's an 800cc, VTwin, mostly aluminium.

    Ok, just messing with ya, it's made 4 hours away from me which means, despite the rather Italian naming, it is most certainly Chinese.

    Yep, that's why I'm sticking with the VW as the base engine for our Duet design (talking to one of the manufacturers about ASTM certifying a model together).

    An advantage over VW would be the lower prop rpm allowing larger diameter props.

    Torque is said to be 73nm between 4000 to 5000 rpm. That works out to 30kW at 4000rpm and 38kW at 5000rpm. Just the size range for UAV engines smaller than the Rotax 912 but larger than the two stroke “model aircraft” type and smaller rotary engines. With the ability to turn a larger prop than the VW engine and quieter than two stoke and rotary engines. The homebuilder might stick to the VW engine, the UAV manufacturer might have different priorities.

    This company is importing components into Argentina.
    I would love to find out how to contact the actual manufacturer of the engine. Might be a good solution for our little single seat plane.

    You go to Alibaba.com and start entering stupid search parameters that otherwise make no sense.

    800cc Engine -utv-800cc Engine -utv Manufacturers, Suppliers and Exporters on Alibaba.comMachinery Engines

    Then you start contacting the trade houses. You will have to deal with them as you couldn't do a minimum order with the manufacturer, would be too big.

    The HKS700E is 60hp at about 120lbs. A "tried and true" design and somewhat readily available. But last I saw was [TD="class: xl65, width: 59, align: right"]$9,372. [/TD]
    More choices is good.
