I think this sums up the mentality of the CAA to a tee. Picture if you will, a night flyer. How many lights do RC night flyers have? Bloody hundreds so the pilot can see it and it’s attitude/orientation etc, agreed? Well under CAA regulations or proposed regulations, I lose track sometimes, you have to ensure you have a green flashing light on it! How many f’in lights do they want before they determine that it can be seen! Unbelievable! If you are going to dabble in a new realm perhaps it would be a good idea to consult someone from that realm and perhaps try listening to them!
