Michiel,
I haven't started building yet. I have just started my very first model ever. The Jolly Roger. It's nothing spectacular, but I'm a newbie and practice makes perfect, right? However, I do hope to get to your level of actual building models. What you have done is spectacular!
I actually have bought a Minicraft Titanic 1:350 and want to install LEDs as I am putting it together. The LEDs is what actually led me to this post. I have been trying to get some ideas on how to install, what size LEDs, on/off switches, etc.
Great job!
Karen
