Hi Dale,
I will be at Oshkosh with the UL power CH650. See you there.

Hi Gus,
I'm building a CH650 and I've been following the development of the UL260i for over a year. I'm VERY interested in what you've built. Do you plan on having it at Oshkosh? If not, do you plan to be there?

One of the benefits of the FADEC system is that you can run the engine at any power setting (fuel burn) you like. A particular aircraft will take a certain amount of HP to go a certain speed. That means fuel burn. Keep it light and clean and and it is better, also the fuel injection saves a bit of fuel per hp. Real world I am seeing 125 mph at less than 4.5 gph, it will do 135 about 5.3gph. Best is about 80 and 2+ gph. So, yes it does burn 3.2 per hour, and a lot more and a lot less. Have to relate GPH to speed, but even there can be great variations due to different airframes even of the same design. Anything turbo is still a ways down the road. In testing now is the UL260iS which has one point more compression ratio (9:1 vs 8:1) at 104 hp.

What a great looking airplane! What is the fuel burn on the 260i? The claim is 3.2 gph and I'm wondering what real world consumption is. Also, what can you say about the 105 hp turbo version?

The long nose on the 650 makes it look more streamlined. I like it!
