    Hello everyone,

    at the moment I'm building a pair of Fokker E.III models but I'm not very satisfied with the engine that comes with the model.
    Does anyone have a good drawing, preferably with measurements, of the Oberursel U1 rotary engine so I can design my own?

    Thanks in advance
    Richard

    Oberursel U1 Drawings

    Hi Richard,

    Least I can do is provide you with a drawing in return for the nicely designed Clerget that I downloaded from your site. Thank you! Here is a somewhat imprecise but dimensioned drawing of the U1. Hope this enough to get you started.

    first build pictures

    here are a couple of pictures of the first build of the Oberursel engine.

    http://home.planet.nl/~schul923/new/urs03.jpg
    http://home.planet.nl/~schul923/new/urs04.jpg

    As Gil said that the drawing he posted was inaccurate, I went looking on my old pc for some decent photographs that could help me.
    Much to my surprise I found a drawing that seemed pretty accurate and used this to design the engine, guess it came out quite well.

    comments please.........:)

    Beautiful!

    Hi Richard,

    Very nice! Printing on aluminized stock will do wonders for the "metallic" look of the engine.

    On the earlier posted drawing, not that it makes any difference now, I meant that the drawing was not to scale. The measurements are accurate as far as I can tell.

    Best, -Gil

    Gil,

    I'll see if I can find some aluminized stock and give it a try.

    The measurementss your the drawing were ok, without them I probably would have had to build two or three models to get the scale right. In the other drawing were no dimensions at all, can't even remember where I got it from.

    one more picture of the engine, now under the Fokker engine cover; snug fit and there's even a bit of space left.

    Have to shorten the rear part of the engine because of the 1mm cardboard of the firewall.........back to the drawing board..:)

    Some other work...,

    Richard,

    Nicely done! I've been working on WWI style cowls off and on for several years now. Current work centers around aluminum/paper composite construction. The image shows a U1 in a Nieuport style cowl. It still needs work (as always). Think I'll try a single piece form next. And in case you're wondering whether the composite works like real aluminum metal, rest assured it does very nicely...,
