Classic air planes
« on: 14, September 2015, 05:29:41 PM »
Hello,


Looking at building a EU-1A this winter.


I was wondering if one in the area has built this plane and what engine they used.  I looking for a Webra 80 red head 1039 to although I have seen in the states that people used Rossi 61 black head.


Would appreciate input from others.


Also was wondering about the Moki 61 LS, OS 61 RF and the Webra 61 Red head.


Thank you.

Hi ,
just vaguely remember the EU-1 -was that Wayne Ullery's design? Still have the plan somewhere & I think that shows a reduction drive. Did he discontinue the red drive?

At the time of the design the EU1 was designed around the 10cc piped engine.

Hi
Just looking at the low thrustline - I would probably use an OS 60  rear exhaust upright. Looks like there is enough room to route the pipe  thru the top of the fus & a stinger thru exiting bottom. Would look neat - but a lot of work. Alternatively - mount inverted with pipe underslung.

Exactly, here are a couple of pictures I found while searching around.


Engine is still up in the air pending. 


So are the retracts.  I was thinking B&D but not sure yet if I should use air or mechanical.

That's very nice indeed. I would like to see that fly, quite modern looking apart from the length of the moment arm
