Those extras you are adding are great, Spiros @fiveten, thanks for sharing these with us.

I think that was true of Heller in general, Spiros (@fiveten), but they did make some nice models for their time. I have the EC-121 from Heller, and I ordered some resin and photoetch to fill in the gaps. These sets haven't been around for a while, but I found them on Ebay. The sets are slow to show up, only one has made it so far.

I have done the same thing with my EC-121 many times, except I have never started it. I think about all the cool paint schemes, open the box, imagine the work needed to bring the model up to a good standard, then close the box and start something else.

Thanks my friend @eb801!

Thanks so much for this very valuable help, my friend @airbum! Of course it is ok that you continue from here! So, I am leaning towards a earlier example with lightly weathered NMF ar "areas of interest". I wonder if the decals are ok to represent an earlier example, or they "evoluted" too. Looks like they are more or less the same through the years of evolution, but I might be wrong.

I believe so too, my friend @chinesegeorge!

@stephen-w-towle, based on the amount of parts you would judge this kit as simple indeed, but the amount of work required to make those parts fit nicely and large areas for painting, makes is not that easy to put together. Your dad must have had an amazing job, being responsible for the functionality of such an aircraft must be great. The analog world, how great is that. I do work at a Semiconductor company and still a lot of our IC's do contain analog circuitry, next to digital ofcourse. You can do so much more with analog than digital.

Thank you so much for all these kind, motivating and supporting words, my friends @stephen-w-towle and @johnb! This is a build I started some time ago, then left it aside, only to bring it back to the bench recently, due to motivation risen by John's wonderful build.

Thanks for sharing your memories with your Father, Stephen, it is an honor for me when my build triggers such memories.

Not only you do not need to apologize, but, on the contrary, it is really wonderful that you shared your thoughts here, John!
