EU-1 vs. EU-1A Differences Help
All right historical gurus - a few questions to help clarify things, please.
1. What are the differences between the EU-1 and the EU-1A? 2. Why does the EU-1 plan that I have show two wing roots: one is 15% and the other is 17%? 3. What are the above percentages referencing, ie. 17% of what? 4. What do you guys think of using an old Webra 90 in this plane? Thanks for any and all comments - I am sooooo excited because Don has finished my fuse and will be sending it my way soon!!!! The EU-1A was a dream of mine from the first time I saw its' picture on the cover of a magazine. Gene |

Generally the % of root was the wing's root thickness to root chord measurement. Possibly there were two wing thicknesses envisioned by the designer.

RE: EU-1 vs. EU-1A Differences Help
There are lots of differences. The EU-1 was mostly foam and was larger then the EU-1A. I do seem to remember two different wing sections depending on how much power you think you could get out of a .60. I don't believe anything would interchange between an EU-1 and an EU-1A.

RE: EU-1 vs. EU-1A Differences Help
I am very interested in building a EU1-A, It looks like a good flying plane, for someone like me that just wants to play at pattern, and have nice looking plane this might be the one. I see several people are making fuselage but do not post the wing span and area, does anyone know what it is. The other thing I like about the EU!-A is the up right engine, make a great weekend flyer, but I would like to use a modern engine. Like a OS120AX with a rap around header. Think that would work? Back in the 80’s we had a Eu1 or EU1-A fuse, a friend made the stabs angle down and we cut a big set of wings put a ST2500 in it and he painted it like the F-4, he flew. Real fun plane. T Green

Thanks Dave, That's one of the plane I am looking at to build this winter, just want a good running, crank everytime motor in it. TMG

Tony,
Thanks for your input. I didn't realize that the differences would be that vast - when I receive my fuse for the EU-1A I'll compare it to the plans and post my thoughts for people to evaluate. Gene |

2. Why does the EU-1 plan that I have show two wing roots: one is 15% and the other is 17%? This from the original EU1 article by designer Wayne Ulery. Not quite sure how he quantifies "improvement" and "slight edge". Ray |

RFJ,
That is some great info, but not very conclusive. Thanks for your response. Gene |

RE: EU-1 vs. EU-1A Differences Help
When the original big EU-1 came out, it was really asking a lot from the current .61 powerplants. So the thinner wing was considered to reduce the drag and perhaps the weight a bit. I think that was what Wayne was saying in his article. I don't know what the wing thickness percentage is on the EU-1A, although I did have one. Used it as my back-up to a Tiporare at the 1980 Nats.

Gene,
A shot showing both versions. The Project Pattern articles mentioned were written by Bob Hunt(R) and Dean Pappas(L) and described the building and trimming of this EU-1A from the Dave Scully Aero Composites kit. A most interesting series, it ran from May 1984 until September 1986 in Flying Models magazine. Ray |
RE: EU-1 vs. EU-1A Differences Help
If you closely at the Bobby Hunt model it's got about a million rivets and panel lines on that flawless finish. Cool looking jet style model. I hope that this becomes a popular build soon.

RFJ,
From looking at the pictures you provided, the turtledeck and the canopy area are quite different from the 1 to the 1A. The nose area on the 1A looks to be a bit sleeker, not as wide or tall. The engine head on the EU-1 picture looks lost inside the cowl area while on the 1A more of the cylinder and head are showing. Thanks for your pictures. Gene |

Too bad the project pattern EU1-A met an untimely demise [:o]

RE: EU-1 vs. EU-1A Differences Help
I haven't gotten all of those back issues; What DID happen to that model?

Hi Ray,
You are a living encyclopedia - I can not understand how you can remember where all info from the past is. Amazing. /Bo |
RE: EU-1 vs. EU-1A Differences Help
Bo,
It seems to be a strange phenomenon associated with getting older - I can recall stuff from years ago but can't remember what I did yesterday [&o] Ray |
RE: EU-1 vs. EU-1A Differences Help
RFJ,
Fantastic history :D:D Thanks. Gene |
RE: EU-1 vs. EU-1A Differences Help
Thanks Ray. They must have had that thing trimmed out very well!

Thought I would post a photo of an EU-1A flown by Jerry Budd in the 1987 Lancaster contest.

RE: EU-1 vs. EU-1A Differences Help
Ed,
Thanks for the great pic!! I love the clean crisp lines of his paint scheme. A direct contrast to the rounded lines of today's modern pattern planes. This view of his plane also shows the canopy and turtle deck lines that I have found to be quite different from the EU-1 plans that I have. I like the sleeker lines of the EU-1A. Hope to have mine soon to work on this winter. Gene |
