Look at the weight! over 200 lbs. if I was going to go that heavy I'd use a c-85/c-90, I only know one Sonerai owner, and he repeats the quote often "build it right/build it light" I thought the R-2300 was pretty cool but it is over 185 lbs same as a C-85 basically. Revmaster seems to do alot but if they can't keep it light I don't see the point. Just sayin.

Article made it look like they would try to get it certified sometime in the future, although I cant begin to imagine what that would cost. For about the same weight and HP you could use a Corvair for probably 1/4 the cost, unless you are trying to stick with the vw style engine, even so I think the article said they based it off a type 4? Does this not defeat the purpose of the sonerai since fuel consumption would probably double?

Does this not defeat the purpose of the sonerai since fuel consumption would probably double? it's horses for courses really. If Horvath indeed plans to sell O-200 replacements to the LSA market, comparing his R3000 with a conventional VW based aero engine is pointless. It might look approximately the same, but from the article I gather that it actually is a different animal. As to fuel usage: carburetted engines in about the same RPM range (assuming about the same displacement) can pump only so much air. Assuming near-stochiometric mixtures, fuel useage shouldn't differ as much as you assume... cheers Hans |
