I know this was mentioned a couple of years ago by another member, but I just want to champion Bournemouth ATC. I called the tower at around 1500hrs to ask if I could get authorisation to run a low altitude test flight within the CTR at around 1630 (I am a beginner M2 drone pilot). The lady was so helpful and asked me sensible questions (where and for how long? etc.) and confirmed with radar that it was ok for me to proceeed. I was given a reference no. and asked to call back with it when I was back on the ground, which I did immediately. Thanks Bournemouth ATC for being so helpful.
