If you do color it, please upload your version so we can all build it. I'm probably going to make some more too.
Just a note: I haven't actually built the L-39 yet, so you're basically doing the beta build. The fuselage is taken straight from the IAR-99, so the lines on it aren't very accurate. The wings and tail are accurate, and I did make the intakes slightly larger, and the nose longer. Control surfaces on my models don't generally need to be tested; they're too simple. The parts that generally need it are the fuselages. Because the fuselage is taken from another model, I know it will work for the most part, so when building, look for trouble in these spots:
1: Wingtip pods
2: Nose
3: Intakes
If you find problems elsewhere, by all means let me know, but pay special attention to those three areas.
With the L-39 essentially out of the way, that means I can move on to the next model. So I guess its time to stop putting it off and create the MiG-23. To be honest, I'm not looking forward to this plane; I'm not particularly fond of it, it doesn't seem very special to me, and I'm really not looking forward to designing swing wings again, especially since the last two models with swing wings I've designed didn't really swing very well.
To be honest, I go through a short period in which I doubt I can make a model with each of my designs...I'm just not very enthusiastic about the MiG-23, and I am somewhat enthusiastic about designing a V-22 or SR-71 right now, which always makes me want to start on one of them first. But I put it on the list, and I've been planning to make it for awhile now...so the MiG-23 is most likely next.
I might build the L-39 first though.
