I stumbled across the metal bikini's blog on just that very subject and he's blog is well worth reading if you're a fan of X-wing miniatures, there's loads of great tips and custom guides there from engines, game mats, asteroids assorts.
I liked his version of the YT-1300 engine decal, but I wanted to copy the engine from a pict I found of the Millennium Falcon, it looked great and my background in graphics and photoshop thought I'd give it go.
It took a bit of tweaking, measuring and adjusting colors after prints, but after a while I got there and I'm quite satisfied with the end result. I've attached a jpeg of the engine decals and all you need to do is print them out on 4x6 photo paper without boarders, I do have a caveat though which is all printers are different it may come out larger/smaller or a different color hue. The end result once trimmed out should look like something below and be 79mm in length.
Then with a credit card or similar you can tease the paper engine print into place, no glue is needed as it's a tight fit which is nice should you wish to reverse the decal at any point. I used gloss paper, but think matt may look better. If you try it out leave a comment with how it worked out for you. The YT-1300 engine deca sheet is below, just click on this engine graphic link it to download the full size version.
Have fun and if you have and improvements or YT-1300 mods, please share them. Thanks
