Eduard GE f110 Exhaust

[Shadrik]

I wanted to get two of those for an F-14D build and did some research on the product.

Now, on the eduard site, you will find nice renders, those show beautiful detail and the feathers look correct.

The reviews with pictures however tell a different story. Here you can see that the detail of the feathers is not like it is in the renders,

The edge of the feathers does not feature the, I believe it was called pressformed doubler? Anyways, it's not there.

A bigger problem however is, that the nozzle looks like it is mirrored, as in, the feathers overlap on the wrong side. On the real

thing, they overlap clockwise, on the resin part, they overlap counterclockwise. My guess is that the master was produced via rapid prototyping

and that the CAD 3D model was accidentaly mirrored before production.

Just wanted to let you guys know.

Here the review that even shows comparisons.

Thanks a lot for the warning! Certainly one to avoid...

Get Shawn's set. They are affordable, and very nicely done.

Haha, those are axactely the ones I decided for, just have to put some money on paypal. They look awesome and I prefer their look over the aires ones. :)

I just used one on an Hasegawa 1/48 F-2A. I thought it was great!

mmmm are you sure about this? I have doubts, it's not clear what kind of technology Eduard but also Aires produces these things.

Hi, no, not sure at all, it's just a guess. Partially because of the renders, those have been made in some kind of 3D modeling programm. Also the pictures in the reviews show some odd steps in areas that should be straight, almost like the layers you can see in some rapid prototyped parts. But they are so obvious that it rather looks like something went wrong there.

But I'd be willing (almost) to bet that a lot of the recent brassin stuff has been done by producing masters via rapid prototyping. I have a set of the Mig-29 wheels by eduard, they definately look, well, manufactured. Might be milled of course. The Aires F-14 cockpits on the other hand show definate signs of handwork, especially the side consoles, not that it reduces the quality or anything, I have more of those cockpit sets than I have F-14 kits.

In the end, it's just a guess. I am very happy with pretty much all my eduard purchases, this exhaust is the first of their products with I have found to be very flawed.

But I'd really like to take a peek in the production process, that would surely be interesting and educational.

edit: I just took a look at my eduard mig-29 exhausts, there is a distinct pattern that shows layers. Very fine, I doubt it would show up though even the finest layer of paint, but it definately looks like the master has been build out of a lot of very thin layers. I can't take pictures I'm afraid, my camera has kicked the bucket

I would really like to know something about their production techniques but I think not willing to satisfy my curiosity ........

My products made in RP are far from being perfect, they require a lot of manual work to finish but this is normal when the budget is limited.

I'm about 99.9% sure they're 3D printing their masters. One of the benefits to CAD is the ease with which you can flip/mirror things. One of the disadvantages of CAD is the ease with which you can flip/mirror things. Same with decal software. Much like tattoos and piercings, just because you *can* mirror something doesn't mean you should :)

All Eduard resin I'd seen shows signs of non-human involvement. I don't know if masters are done via 3-d printing or machined, but they are not done by hand IMO. Aires stuff doesn't have these artifacts. I don't mean to say that Aires stuff is necessarily better - they've been known to adapt their existing parts to newer kits for example, at the expense of accuracy.

I have no insider knowledge BTW, so don't take it as gospel - but I think if you inspect some of these sets, you're likely going to come to the same conclusions. To be honest it doesn't bother me how the different manufacturers create their products.

It's likely but since Eduard using milling machines for mainstream production i was wondering if they did not use micro milling machines with NanoBlades since this technology allows for operation at 0.2 mm, i've seen lately an example with the aid of a microscope and surface quality was spectacular than any RP machines.
