(Graham Singleton) ________________________________ Message 1 _____________________________________ Time: 01:10:18 AM PST US Subject: Europa-List: Anyone install a pin and striker on upper rear of doors? From: rparigor@suffolk.lib.ny.us I understand an attractive alternative to reversing strut location is to install a pin on door and striker on fuse. Anyone have this arrangement with original strut position? Whats your thoughts and how is it working? Pic by chance? Thx.

If you have different data, > please let me know If I properly understand, this demonstrates that fuel consumption increases very significantly with altitude, right? I have heard/read a lot of different things about altitude compensation for the Bing carbs. Some say there is compensation by design, some that there is no compensation at all, and some that there is only partial one. I would think now the second statement is the right one! My own experience (without having a flowmeter nor CS prop) is that I have never seen an apparent MPG increase by flying high. I would be interested in seeing some other data confirming yours.

I note the increase in fuel consumption is almost linear from 3K to 7K ft while the increase between 7K and 9K is double that between 5K & 7K. I imagine 22.6" MP at 9K would be wide open throttle so I'm wondering if this kick in the consumption is because of power jets coming into play. Regardless, there is nothing that can be done about it with things as they are so I can certainly understand your desire to install a mixture control. I look forward to hearing how you accomplish this. Sorry I am unable to supply any comparative data yet. BTW, your MPG figures appear to actually be NMPG so your actual MPG is still way ahead of any motor vehicle travelling at 146 MPH. Realizing that may make you feel better No? Somewhere I saw once that Rotax actually do have true altitude compensating carburettors but for the life of me I cannot recall where I saw that. Cheers Kingsley ________________________________ Message 4 _____________________________________ Time: 05:12:02 AM PST US From: "David Joyce" Subject: Re: Europa-List: Re: does rotax need egt? Kingsley, For what it's worth my 914 mono XS + speed kit has given the following figures in careful trials: At 2000ft 100 kts TAS 12 litres/hr 110 " " 13 " 120 " " 14 " 130 " " 18 " 140 " " 23 " At 10,000ft 150 " " 21 " This suggests that unlike the 912S, the 914 is able to adjust adequately for altitude, and I suppose that should be no surprise.

And the turbo keeps everything pressurized, including the carbs. The engine, nor the carbs, would notice the difference between 2.000 and 10.000 feet.

I think it is indeed sad that many of you have a partner who is not involved with flying or building. It is great to make plans for travels together and to build an airplane for that together.

Oh, and don't forget the owls, often demonstrating excellent landing flares, and superb L/D ratio's while we were working in the late evening. We've had quite some spectators. ;-) Thanks, Frans ________________________________ Message 8 _____________________________________ Time: 04:44:48 PM PST US From: Graham Singleton Subject: Re: Europa-List: Re: does rotax need egt? jpg12305 wrote: > If I properly understand, this demonstrates that fuel consumption increases very significantly with altitude, right? > > I have heard/read a lot of different things about altitude compensation for the Bing carbs.

It involves adjusting the overpressure on the carb float bowl, which has a significant effect on mixture. Don't try this at home without consulting a Rotax expert. You definitely need EGT to see what's happening.
