Well, in short, it ended that he and mostly Martin did most of the work. I just could not do it good enough. Later i run into a guy looking for a job, and hired him to do the filling and sanding work on the rest of the plane. My deepest respect for those who did that part of the project themselves. The moral of this reply: Look for help if needed, instead of letting the build come to a halt.

I used 400 grit, and the final paint finish was nice, although I noticed over time that sanding marks came through. Someone suggested to me that I should use 600 grit, but I wondered if this would cause paint adhesion issues. Paul ________________________________ Message 3 _____________________________________ Time: 10:02:02 AM PST US Subject: RE: Europa-List: Mixture control From: "Terry Seaver (terrys)" Hi Greg, We have been flying over 7 years, but only about one year since installing the mixture control. My partner, Dave DeFord did most of the testing, so he knows the specifics better than I do. As I recall, we can reduce fuel flow 5+%, at altitudes of 8000-10000 feet. It doesn't work well at full throttle, because it requires a pressure difference across the carb butterfly to work. This means it is less effective at very high altitudes where you would need full throttle to get to cruise power. The device we used is the Green Sky HACman mixture control system, see their URL at; http://www.greenskyadventures.com/bing/HACmandetails.htm regards, Terry Seaver A135/N135TD ________________________________ From: owner-europa-list-server@matronics.com [mailto:owner-europa-list-server@matronics.com] On Behalf Of Greg Fuchs Sent: Saturday, January 10, 2009 9:06 PM Subject: RE: Europa-List: Mixture control Terry, I like the idea of compensating the Bing carbs which would tend to run rich at high altitudes, anyway. Are you flying yet? Ie: Have you flown this arrangement, to see how well it worked, or how much fuel was being saved? Thanks in advance, Greg Fuchs, A050 Hi Remi, We are members of the Experimental Aircraft Association who have built an 'experimental aircraft'. As such, among other things not included in our standard kit, we have installed a mixture control on our 912S ..........snip.... regards, Terry Seaver ________________________________ ________________________________ Message 4 _____________________________________ Time: 10:49:40 AM PST US From: "D Wysong" Subject: Europa-List: Re: engine surging > Anyone have better info on where to put the needle clips? The 914 Heavy Maintenance manual (ed.21/rev.2, 73-00-00 p.28) says to refer to SI-914-013 or SI-914-015, depending on your airbox part #. If your airbox part # is 667167 (etched on the aft face of the airbox), then your jets should be 156 (cyls 1/3) and 158 (cyls 2/4) and the clips should both be in position 2 per SI-914-015 (pg 3, paragraph 3.3.2). ________________________________ Message 5 _____________________________________ Time: 04:10:33 PM PST US From: Graham Singleton Subject: Re: Europa-List: Fein saw Greg Fuchs wrote: > > Graham, > Thanks, at least I know now that the original Fein tool works. > It does seam like it would work with fiberglass like a knife through butter. > Regards, > Greg Greg & All not exactly like a knife through butter! It isn't a fast cut. The important thing is in the name, it's a "fein cut" and it's also very controllable. IOW you won't make knife /chisel slips and ruin anything.

You might get a few extra knots cruise speed. (probably would imho) More or less what the glider fundamentalists do.

Let me clarify the statement: If the fein knockoff comes close at all (in every way) as being as fein as the fein saw, then all is f.....pretty good. Cheers!
