I agree with the simple paint scheme. It seems that now days many people (including myself) tend to get carried away with making the paint scheme too "busy". Jerry did and still does work for NASA at Edwards air force base and hence the NASA on the tail. I flew pattern in the southern California in 1986 and 87 and I have been going thru my archives of photos from the times when I came across the picture. As Tony F mentioned above, the EU 1 and 1A required a LOT of horsepower to make the plane perform. As I recall, Jerry had an OS that was really strong. He sold me a rear exhaust OS 61 that I flew in my Tipo and then later in one of Tony F's Challenge 3's and that thing was really strong. If memory serves, he took a carb from an OS 108 FSR and mounted it in the 61 that I bought from him. I don't remember the numbers but my 61 turned a Zinger 10.5" X 7.5" prop well above 15K. Every time I think about that engine I kick myself for selling it. Since then I have sold very few of my OS engines.

Incidentally, for those that might not know. I believe that Jerry was one of the first guys to start soft mounting the 2 stroke engines (as early as 1986). He used to have a company called "Planes and Things" that made a lot of "pattern" types of stuff. His system mounted an X shaped flat aluminum plate to the back of the crankcase (using the four engine backplate mounting bolts). This plate was then mounted to four rubber isolators that were mounted to the firewall. I believe he later sold the system to Sullivan or DuBro. I know this was a little off track, but I just thought I would mention it.

One last thing. In going thru my photo archives, I have found and posted a number of photos of classic pattern planes from the mid 80's in southern CA. I have posted these photos in the "classic pattern image base" thread in the RCU Classic pattern section.

Wow! Ed!

I've been waiting for someone to verify the performance of a OS 61 with the larger 7D carb. I asked a while back and suspected that the 108 FSR version of the 7D carb would have a higher top end and more power. Good to here it.

I have several different versions of the 7D carb, one for the regular 61 FSR/VF, one for the 90/91FSR, and one for the 108FSR. The only difference I have found between the 3 of them is the size of the carb rotor.

OS made 2 different inserts for the 7D carb.Smallest diameter insert was for the 61 sized engine. The larger diameter insert was for the9091 FSR with no insertfor the 108FSR. As it turns out these same inserts also fit the 7M Carb as well.. You could also use the inserts for the 90 and 108's if you wanted. No info on why you would. Only thing I could think of was that maybe by using the smaller inserts on the larger engines you could get better fuel economy or maybe tune them better.

The only requirement for the OS 61 FSR/VF to use the larger diameter insert or no insert , according to the 7D carb manual, was thatyou would need to utilize a pump to get it to idle correctly as the engine tended to have trouble drawing fuel with the larger openings.

Here's the EU-1 Article. Any one got a article on the EU-1A?

Anybody have plans for the original EU1? I don't think M.A.N. sells them anymore.

Roguedog

If someone could scan the EU-1 articleplan pages at 1600dpi and send them to me I could produce ausable set of plans. The resolution of the article pics I postedabove is to low to be of any use for a usable set.

Check post 25 on page 1. Gene, who started this thread, has a set of plans for the EU-1.

In a former lifetime I flew an EU1-A with Dean Koger at Wright Patt AFB and loved it. And a few years back before they went out of business got a complete EU1-A kit from a place in TN. It sits here in my shop ready to build. After reading all of this guess what my winter project will be! Sure glad I found this site.

Dick,

If you have time during the rigging - post some pics of your install to provide ideas for everyone else.

Thanks,

So, in the last few minutes after reading all that good stuff, I went to the shop to see what I really do still have. The fuse is still stuffed with paper, the wings and stab are still firmly taped in their cradles, and I have the complete Aero Composites 14 page "how to build it" with full size of rudder parts needed etc. And I guess way back then I wanted info, so I have 27 pages of articles from Flying Models from 1984 thru 1986 on all the inside details on how to build the bird.

Guess I best get some balsa to make the sheeting, and then try to figure out what the technology of today says to use for sheeting foam wings - the articles back then used epoxy mixed glues!! Anyone wants copies of any of that stuff let me know. Dave Scully was Aero Composites back then and my buddy that helped me make both the EU 1A and Phoenix 8 that I flew back then. Am still flying a Kimbro Deception.

Dick,

That is some great information. I would love a copy and would be happy to pay you to send it to me. I will PM you with my address and info.

Thanks, Gene

Flywilly,

I was looking on the internet last night night and found a website called airagestore.com. They sell plans for the original EU1 along with some other interesting pattern planes and allot of other different types of planes too. When you open the website look under the "Plans: tab under "Pattern Planes". You may want to check them out even though they are located up in the great white north.

I read you wanted and didn't have these instructons so I sent them to you.
Merry Christmas!

Dick,

welcome aboard! Like Paul said, this forum is where classic pattern is at.

Don,

I don't know if you have wing/stab planform measurements as well as airfoils for the EU-1A but if not, perhaps Dick could help with that using his cores prior to building. I didn't see anything in the building manual other than the tip templates (boy, does the manual ever look like the Tipo instructions!) We wouldn't want you to be without airfoils come Thanksgiving!

David,

Air Age Media is the publisher of MAN and a slew of other R/C magazines and books/DVD's. They are big. However, they are not located in my neck of the woods (I assume that's what you mean by the "great white north"), they are located in Wilton, CT. I just had a look at the website and they do have a nice set of plans. I'd never visited the site - nice! Thanks for the info.

How about the dihedral? Do we have that number? Supposedly cut into the cores .

doxilia

My Feedback: (3)

Good point Paul,

there doesn't seem to be any indication in the MAN plans posted by Brian above. Maybe it's in the article or perhaps it's meant to have a flat top.

David.

mercura

David,
It may be that this design has no dihedral. This is not uncommon in designs with the wing located on or close to the thrust line.
There is no reference that I can find in the plan artical to dihedral.

If you look at the fuse plan it shows the dihedral brace.

ah... you have the wrong plans... thats the "UE"-1A . lol..

still cant figure that one out.
Does anyone know why it is called the EU-1A??

Ask?

Did find this post,
I do not know if Wayne Ulery is still with us but just as with the Taurus I often try to have contact with the specialists of the originals.

See post 8 of this thread, I cannot copy a direct link:

Guys

I got the following from Wayne Ulery this morning. I guess the quickest way to document is to ask the designer.

Hello Steve:

As I remember, I took the EU-1 to the Toledo R/C show in the spring of 1976 and did not test fly it until the summer of 1976. The reason this date sticks in my mind is that I put a red, white and blue color scheme on the EU-1 and also remembering that it was the 200 year celebration of our independence. So I don't think it will be legal for the Classic Pattern. Thanks for your email....those were the "good ol' days" weren't they.

Regards, Wayne Ulery

Bryan, there’s a lot going on in this thread, but I was referring to the FG EU1-A kit.

MMcConville

My Feedback: (4)

I know that one. Its named after Wayne's wife which starts with an E (forgive me Wayne I cant remember her name). E Ulery-1

The A is just because its the second version of the design.

Ron Stahl

My Feedback: (12)

Just like Geoff Combs LA-1 is named after his wife and daughter.

MMcConville

My Feedback: (4)

Almost.......... That one I do know. Geoff' s wife Laurel Ann = LA-1 and his daughter Stephanie Lauren = SL-1
