Were they taking orders on the S-LSA -12?

That's very interesting data Scott. This will hopefully put to rest the debate about how much better fuel burn numbers the iS engine delivers. Nothing like a side by side test.

A 25% reduction in fuel consumption equates to 33% more range, which would be like the original RV-12 having a 26.3 gallon tank without the extra weight. You really can eat your cake and have it too!

That seemingly equates to about 4.5 gph for the 12iS. Very very impressive.

But not that the engine has higher cooling demands......

BTW, I even brought up this thread in a meeting at OSH with one of the Rotax engineering reps visiting from Austria, the Distributer Rep. for Canada, and distributer Rep. for the U.S. and suggested they contribute. All I got was a smile and a firm NO. But once again a verbal confirmation that all airplanes converting from the ULS have had to make adjustments to cooling......

It doesn't help us understand why without technical details. It seems none of these folks you talked to knows or is willing to say so I'll let this one rest until a knowledgeable Rotax engineer tells us why this is so- which may never happen.

I sent in my check for the new fuselage this week. I'm curious if anyone has any idea what the lead time will be for delivery? I check Vans lead time page and it says 12 weeks for the -12 fuselage. I was really surprised to see that the wing kit lead time is now 20 weeks! Is that due to the OSH announcement or some other reason?

I agree on the not understanding why part (and know one has tried to provide an explanation to me).
At one point the discussion in the thread seemed to be leaning towards it defying the laws of physics so it must not be true.
I can assure you it is.

The current goal is to try and begin shipping fuselage kits in October.
The listed lead time for wing kits is because of a back on parts deliveries by a vendor.

When will pricing become available? Is the iS engine going to drastically increase the price?
