We regularly fly 1 1/2 hour flights. They are so comfortable and we have done two 4 hour legs in a day many times with no discomfort. The only down sides are they are heavy and somewhat expensive and really hard for the first few minutes when cold (Michigan cold)!

To help me understand if the investment is worth it: Are the cushions drop in on the Europa? What I mean is do they take care of the challenging angles of our back rest? Or did you have to come up with some structure on the backrest and the Oregon cushions are just a few inches thick. That's the way it is in my LongEZ, the Oregon cushions are just a few inches thick and you have to add any filling you need underneath and on the back. Not a problem but it doesn't help figuring out the proper geometries to make our seats comfy enough.

I have 1100 hours on my XS mono, N262WF, with the 912ULS engine. The engine is unmodified and I have had zero issues with running rich during that time. Also the engine has never missed one beat. A few comments :- * My flying is typically a mix of recreational trips and visits to local flyins plus flights to Sun N Fun (8 times) and Oshkosh (10 times). Local flying is usually done at part throttle and averages about 4 gallons an hour door to door. My longer airshow trips are normally done by climbing to get to smooth air, usually above 5,000 to 6,000 ft., I then set full throttle at 5500 rpm with my Whirlwind C/S prop. In the summer, I often have to fly higher to stay above the tops of towering cumulus and occasionally I get to 11,500 ft. * During my early test flying, I did a check on my Service Ceiling. I loaded the plane up to gross with a full tank and borrowed some oxygen gear. At 16,000 ft., the plane was still going up at 200 ft/min so I was happy with that. * The bottom line is that I have had absolutely no problems with rich running. The engine has never missed a beat and the CHT's and EGT;'s have always been in spec. The condition of the plugs at routine replacement has always been good. At the last condition inspection, my cylinder leakdown numbers were 80/80 on 3 cylinders and 78/80 on the fourth. * I did consider installing a Hacman package a long time ago when I saw some discussion on the subject. After consideration I chose not to do this due to the high amount of administrative work and knob twiddling required for this to run satisfactorily. It also will kill the engine if leaned out too far and that was unacceptable for me.. * With my C/S prop, all my flying is done at rpm's between 5,000 and 5,500. * I note that my Rotax Operators Manual specifies - /The engine allows operation with fully open throttle over the whole r.p.m. range without limitation. But full throttle performance above 5,500 r.p.m. is limited to 5 minutes./ I comply with that. I also see nothing in the manual which suggests that rich running is a concern.

Read "normal" were the engine is not running overly rich and causing other issues such as fouled plugs? Yesterday I did a fairly long cross-country around Florida (about 3.5 hours total) and on the return flight I was getting beat up by turbulence at 5,500 feet (can the Europa be rough on turbulence or what??). I understand the 912 is still happy at 5,500 but what about higher altitudes. I put up with the turbulence. Rather silly since I could have just tried to go up to 7,500 feet) but not knowing if the engine starts running too rich to be happy I just put up with it.

We recall someone took a cockpit module to them and they made patterns from that. They even have the cut out for the pip pins that go into the spars. I notice that Europa isn't listed on their website. We purchased ours back in Jan Feb 2005. From the invoice it looks like the part numbers are 3014711-700 left cushion 3014712-700 right cushion If they look at our old order there may be some confusion since we also purchased a third set which sits on top and in front of the other cushions. Heather uses that to get taller and more forward and it works in either seat. It is useful for YE rides, and is easily removed for "normal" size folks. You probably won't need that. We'll get some photos the next time at the airport.

ChrisHere are (first) a couple of photos of my back rest note that I used a couple scraps of blue & green foam to form a lumbar support which I=99ve found to be very effective. I am 6=99-1. For the seat cushion, I too felt that I was not getting sufficient thigh support; note that although I extended the blue and green foam forward of the vertical face of the cockpit module, initially I had not extended the plywood seat frame enough and had to go back and add to the frame so it aligned with the foam. BTW, Beneath my foam seat assembly, I have two thicknesses of 1=9D rigid insulation. It works well for meam just now in the process of having ultra leather covers sewn up for a little =9Cpleat and roll=9D job which wraps around and is stapled into the plywood frameframe is 1/8=9D mahogany plywood with edges doubled up for staples .. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/europa-list Browse Digests http://www.matronics.com/digest/europa-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
