Who was it who is into RC Plane models?

Doesn't it? 

It's me that goes model flying Chris. I've not seen this particular model before, but there are a number of very large models out there. One fella, American I think as many are, had a cracking model of a B29, some 18 feet wingspan IIRC, he flew for a few years. It crashed once and was repaired, but I think he retired it completely a few years ago. 

Some of our memebers have banded together and formed a "Leuchars" group. We've had to jump through some hoops to get registered to fly there when it's free, on the proviso we don't break anything! (Seriously -  they mean runway lights etc of course, it still being an active air base).

Cost-wise, the small jets at our club come in around the £3000 mark all up, the bigger ones maybe £5-6K; they generally need a bigger airfield than we have to get back in safely. 

As for engines; they are just miniature jet turbines that run on kerosene or Jet A-1 if the pilot is feeling rich! The largest ones in models in our club cost around £2500 new. up to aroung £5k for the largest And that model will almost certainly have four, just like the real thing!  

No different to any other UAV (for the moment anyway).

At many clubs, ours included, part of the safety procedure is to have a fire extinguisher close to hand "just in case". I imagine there have been model turbine fires somewhere, but no-one I know has experienced it; they seem to be inherently pretty safe. 

In contrast, I've seen at least two 2-stroke fires in models (one in flight, which was exciting to watch!) and another where the battery in an electric-powered model decided to go bang. The i/c model was able to be landed, the leccy one crashed!
