So... I was going to paint them... in fact, I got as far as spray priming them, letting them dry and getting all my paints out. Then... I couldn't work out what paint to use so I put my paints away again.
It isn't all bad though. I have got as far as cleaning and assembling the bodies/bases for the next three. I've also put the first dome of putty on for the three of them.
I have also sourced enough sky-pikes for all five of the Controllers (plus a couple extra, should I need them later).
