I have finished work on what is possibly my most complex model to date – the limited release Primaris Captain with plasma pistol and interchangeable head!

As you can see the plasma pistol is always on, but the helmet with the LED eye lenses and the bare head (without LEDs) are “hot swappable”. Check out the video below.

This was achieved by hiding a transistor socket in the neck which the legs of the LED could then slot into easily. Now I’ve shown this works, I’ll probably use this technique again in the future.
