Euan,
I think it is being flown in Germany. I am well aware of the LMA scheme in the UK.
However, I think the point I raised did not register with our American and Australian friends, it was, this : with the exponential growth in these models, weight, thrust and therefore fuel capacity I wonder at what point might the regulators call a halt. I KNOW our activities are being watched.
They are no longer” just model aircraft” they are missiles with very considerable energy. Remember the drone issue and the regulations which followed .
I think it an entirely reasonable question to ask in a changing world, totally undeserving of some of the replies posted above.
