Here are some of the projects I have built over the last few years........

'The End of The Line' - the first layout in the UK that really integrated radio control vehicles as part of the story. The vehicle in question was the first of its kind that had all it's mechanics and battery hidden, and was able to actually carry a payload. Things have moved on a lot since then.
