Hi Ken, thanks & good advice. I'm into Arduinos ATM and most of the UK gross product now resides in China!
One thing at the back of my mind is automation, especially since seeing a UK model glider record during Christmas, with a glider crossing 22 miles of open water. It was launched from a chopper and flew via GPS to Lundy (island) and landed within a few mts of the runway! (basically circled until it landed)
They wanted to fly to France but the French.... Well, they're French
