gbigs Posted February 26, 2015 Author Report Share Posted February 26, 2015 Do you know why they chose the 6 cylinder over the Lycoming 4 cylinder? Most likely because Lycoming would not sign up to 91UL and certification (Pipistrel Panthera got a bump when Lycoming told them they would not certify a 91UL engine). Flight Design has also said they are detuning the big-6 from the 195hp engine to 180hp going for lower RPM and slower speeds to 155ktas target. Frankly, the 91UL does us no good in the USA unless you are near a wholesaler that has non-ethanol gas. Link to comment Share on other sites More sharing options...

That seems odd. If it were me I'd leave the engine as is and set the maximum continuous power at the 180hp rpm number. Then the pilot could at least have the additional 15hp for climb.

FlyingMonkey Posted February 27, 2015 Report Share Posted February 27, 2015 That what they did with the Carbon Cub. That thing is an animal. Sonex did something similar to get the Jabiru 3300-powered Sonex to be LSA legal. When you buy a 3300 you can specify it as a "3300A". The only difference is the data plate, but the 3300A is restricted to 2850rpm max continuous. And of course nobody would ever fly at higher RPM if the data plate says no... It's a total scam, but legally skirts the LSA problem. Jabiru will even freely convert back and forth between a 3300 and a 3300A, you just have to send them your data plate and they will send you a new one of the other type, in either direction.

Tom Baker Posted February 27, 2015 Report Share Posted February 27, 2015 That seems odd. If it were me I'd leave the engine as is and set the maximum continuous power at the 180hp rpm number. Then the pilot could at least have the additional 15hp for climb. The de-rated power is likely for many reasons. Some of the likely reason are using auto fuel, increase reliability, lower noise emissions (a big one in Europe), and longer TBO. The original engine at the higher power settings does not have the best reputation in the field. As the reason they chose the Continental over the Lycoming one can only guess. I think it has to do with selling in the world market, especially the Chinese market. With Continental owned by a Chinese company and their plans on Asia manufacturing there, it makes selling there easier. After all it is one of the major growing markets in aviation.

IrishAl Posted February 27, 2015 Report Share Posted February 27, 2015 Could it be because the Lycoming has not been certified for Mogas? Link to comment Share on other sites More sharing options...

Lycoming will never certify the IO-390 for Mogas. http://generalaviationnews.com/2014/03/03/pipistrels-panthera-and-mogas/ Link to comment Share on other sites More sharing options...
