Thanks Blake,
the IR issue was really about, not being able to fit the IR mushroom had I chosen to make it a "night fighting King Tiger", and that would be a petty later on. It's fun to combat other tanks with IR, and I don't want to miss out on that with my Tamiya.
I'll buy and install a IR battle system later on, but am not in a hurry. Main thing is that the King Tiger works.
Oh, my next project... It'll probably be the StuG IV modifications that I wrote about in the Heng Long thread, and it'll be a cheap re-build, since I already have everything at home.
After that...don't know. I have about five other future projects to choose from!
Cheers, Jens
