Hi Plastic...
You're right, the box does seem full of bits...might keep me occupied for a while.
I did build the Revell one years ago, but nowadays with mini/micro radio gear and motors, plus lipo batteries, it might be easier to keep the weight where it's needed. If I remember correctly, I ended up attaching a steel bar under the keel to keep it from falling over, so I'm hoping that this one, being a bit bigger, shouldn't need anything like that.
Not sure about the photoetch yet, I want this one to be a working model (maybe even a sinking one, with the radio built into a small cylinder) so I don't want it to be too fragile. I'll have to have to do a lot of research into it before I make a start on it.
