So that must be a Good engine overall. The weight you listed for Rotax appears to be the dry weight and the weight for the air cooled UL Power is the installed weight. Add up all the cooling accesories for the Rotax(and the water) and its a whole new ball game. There must me a good reason why Zenith has now listed it 1st on their engine list and has installed it on their demo (650/750) aircraft and is in the process of making the FWF kits for the 701 too... I suspect this will be good competition for Rotax. Maybe they will come down a bit and I will be swayed to lean back in their direction. For now, I am going with the UL260is which appears to be about 3lbs lighter when all things are weighed in...

The O-164 is the 100 hp version. See: http://www.flycorvair.com/corvair.html#Engine Specs I think weight is broadly the same for both.

Yeah, the 750 definitely puts the S in STOL, I've seen videos with as little as 50 feet required for take off, maybe even less than that. I think it is tricycle only though there is a float kit for it, and I think makes a great amphib. Yeah, I saw the PT-12, very beautiful as you say. And I love the Cubs too, they look like so much fun. Thanks for reading along, I need to try and make better progress so there is something to see! Paul Thanks for the comment Wayne.

My first and continuing impression of the wing was, "Oh my that's a barrel full of lift!" I'm guessing that the short-field performance must be pretty good. it looks like it would be nice with conventional gear--do you have a choice with this plane, or is it tricycle only? The fellow with that beautiful Ryan PT-12 was there again this year. Did you see it? This year I got to talk to him and thank him for flying her in, which was nice. The polished BE-18 was nothing short of brilliant in the desert sun. What a beauty. I have to admit I'm a big fan of tube and fabric, though. Fully half the pictures on my camera are of Cubs and their cousins. Anyhow, nice job on your continued build. It's been fun to follow along.

Thanks for checking out my blog and good luck with your plane build. I think I got the horn angle right, I don’t notice anything misaligned, but I didn’t do anything special as far as I can remember.

If you can, expand on it and add spec comparions: cc, drive system, cooling system, etc., etc. Additional factors: service and support, warranty, fuel consumption, etc. Great chart – we get many requests for a good comparison of all available suitable engines.

congratulations for the ch750 building, and as i can see, you are working on it alone. double congrats to you.

i want to ask, as we are in the same boat building this nice ch750, about the HORN ANGLE.

once you make a line on the spar (8 mm to the left), then, we are asked to align the horn angle to the line that we have just made. did you get the horn angle aligned with the line on the spar? i didnt get these two parts align because there are about 1-2 mm mis aligned.

so, do you get this right?

thanks
