From: "h&jeuropa" I've spent a lot of time in the back since EFIS CPU was mounted there and to do Mod 70. What I found was that a cardboard box in the baggage bay the same height as the bottom of the D opening supported my stomach comfortably and kept the sharp edge of the opening from cutting. My legs ended up between the headrests.

Sad, I did told them both! Airmaster did ask the question but got no reasonable answer. I can recommend the Arplast prop but the engineering is not quite as elegant as the Airmaster and maybe the Woodcomp. The Arplast fixed pitch prop is also excellent but in the case of the factory I think "it wasn't invented here" may have something to do with the decision to stick with Warp.

Dear Europaphiles, There has been quite a bit of discussion lately regarding choice of propeller. If you have not bought your prop yet, you may wish to consider a Whirlwind hydraulic constant speed prop. See http://www.whirlwindaviation.com/series100.php I have flown 500 + hours with mine from new and have found it to be highly reliable and it gives excellent performance. It is also one of the lightest props available with a weight of 9.3 lbs. I bought it after hearing Kim Prout at Oshkosh many years ago. Paraphrasing, he said that it was the most significant single contribution to the performance of his Europa. I believe that the Series 100 Whirlwind prop was designed specifically for the Europa and for details of the performance of Kim's plane, you can see the CAFE report at http://cafefoundation.org/v2/pdf_apr/Europa%20APR.pdf As you will see, Kim's Europa Classic with the 80 HP 912 is no slouch. For take-off, I set the vernier control to max which gives 5,800 rpm and after take-off, one can easily wind back to 5,500 rpm while remaining at full throttle. I normally cruise at settings between 5,100 and 5,500 rpm. To install this prop on a 912/ 912S/914, you must have the gearbox modification which allows the governor to supply control pressure oil to the hollow drive shaft. It is preferable to specify this before you take delivery of the engine. The Czech made Jihostroj governor which is supplied as part of the package has proved to be completely reliable and is very accurate. The governor mounts on the engine auxiliary pad which is normally used for a vacuum pump, so one has to rely on non-vacuum instruments. I have no business relationship with Whirlwind. Please contact if you have any questions.

I note the Whirlwind series 100 is 66" diameter...How do you feel about that size?...Are you mono or trigear?...How do you rate the WW noise level?

Hi Stevie Now I have some questions. The wheel ramp attachment bar, where did it come from? Was it with the trailer or did you make it. They are self made. There is one extra advantage with them: the ramp has quite a tight fit to the monogear and they are difficult to separate. By using these attachment bars /giant turnbuckles you can force the ramp move upp AND also down (by chain only upp). Look at the attachment. Did the mud guards come with the trailer or did you add them. As you can see I don't any. The mud guards come with the trailer with one axle. The other safety axle and it=B4s mud guards have added here later. Because of my accidents "tail wheel drops down when pushing the plane to the trailer" I will instal this week a floor to the trailer. I think it prevents some future damages and also it will prevent shit coming when towing. Probably one day I have also walls and roof and the trailer is modified to be a lorry... Extra main wheel ramp is also an essential equipment - I will have it also soon. I wanna point out I really respect those people who are able to rigg Europa alone. When only moving wings alone my heart has a rate of 200...

Hi Keith I did not like those original rubber straps and removed them. I made new supporters just like you described them. They are 2" /50 mm thick wooden blocks (birch plywood board) and I shaped them by CNC cutter. They match well to the wing section and between there are very soft self adhesive stuf, douple layers. If you like to get the drawing, please contact me direct. Because the pip pins let the supporters to move a bit, I secure supporters to the trailer also by extra 13 mm / =BD" bolt & nut. There are still some movements between wings and trailer supporters - to prevent any damages in my first class wing surfaces I cover the wings by kitchen film before dropping them to the trailer. The spars are secured by clamps tightened by bolts - not only by pip - pins like original factory trailer. I do not wanna get any damages to the spars=B4main pip pin holes. I have also some other modifications like douple axle for security reasons. Look at the pics. The riskiest part to operate Europa in my case has been so far when pushing it to the trailer: - I have almost destroyed my rudder by hitting it to the back door of my van=B4s (it was open) - main wheel gate opened when towing the trailer (I was lucky Europa did not dropped to the road because it was fixed by bolts in the tail wheel and it was not on it=B4s side because I have extra side supporters). To prevent this situation meet me again I connected those turnbuckles keeping gate up together by a strong rubber string with hooks which prevent them to open spontaneously. - tail wheel dropped from the rail and transponder /DME antenna went broken - tail wheel dropped yesterday again from the rail and Dynon=B4s OAT sensor went broken and penetrated through Europas stomach (so I have a similar extra hole in my Europa=B4s fuselage as Ferg Kyle has his wing=B4s leading edge!) Personally I think the only almost safe way to carry Europa on the roads is to carry it in a big enough lorry /truck with closed coach. No towing at all. Only flying...

Does anyone have a wing profile forward of the spar at the position of the wing support on the factory trailer? On my drawing this is 2 metres from the root spar pin bush. If anyone has one they could email or post to me I would be very grateful and it would save a lot of work trying to transcribe it from the wing. I need it to get the trailer wing supports made.

Thanks for that information. Whirl Wind is local for me (Ohio), and I had not realized that their 100-series prop was designed for the Europa. It looks like the photo on their website is also that of the Europa. But I am a bit uneasy about modifying the 914's oil system, and also about losing the auxilary pad (which I had planned for a second alternator). I spoke to Whirl Wind and they said an electric governor is a possibility, but I did not press him for details. --- John & Paddy Wigney wrote: > > > Dear Europaphiles, > > There has been quite a bit of discussion lately regarding choice of > propeller.
