I am(was) working on this conversion and my advice is not to bother. If you look closer you will see that Welsh is totaly wrong. The prototype, which I think Revell has it captured spot-on, is a thicker stubby looking aircraft where the Welsh is much thinner and obviously longer. Also the the tail starting from the last window has a very noticeable drop where the Welsh is almost straight. The wing attachment is also a problem as the Revell's are thinner and will require a lot of putty. As it does not closely resemble an RJ100, I will not waste my NAZCA Aegean decals. I've stopped working on it and as soon as I locate which box I have my second RJ85 in, I'll start doing some chopping. Just my two cents.
I just realised that this is my first post here so hello everyone and happy moddeling.
