I’ve just finished building the ICM 1/48 Dornier Do217J-1/2 and although the kit is pretty good, some of the detail is a bit chunky especially the FuG202 Lichtenstein radar aerials on the nose. This is due to the limitations of injection moulding so looking around for alternative aerials I found these 3D printed ones by Gaspatch and ordered some;


Having a look at them tonight they are a HUGE improvement over the kit supplied aerials so VERY carefully I separated them from the sprue (or whatever you call the thing 3D parts are attached to). I did manage to break a couple of the upright dipoles but these were replaced with heat stretched sprue. I drilled holes in the ends of the four rods so that I could glue some wire into them to make them removeable for handling and painting.
I have to say they look MUCH better than the kit supplied aerials and previously this would have been a very tedious and time consuming job using heat stretched sprue or fine wire soldered together.
This picture shows the kit ones;

That works for me! If you are going to build the ICM Dornier 217J and were to make just one improvement to the model I would highly recommend getting these from Gaspatch. They are not overly expensive even with postage from Greece and it will save you a lot of heartbreak trying to make your own.
You can get them direct from Gaspatch;

Highly recommended!
Edit;
Costas at Gaspatch Models emailed me today telling me that I have not removed the supports between the upper and lower aerials. I have now done this;

Many thanks to Costas at Gaspatch for pointing that out before I got any further.
