Welcome to our Forum, from Hauptmann, across the Pond in the friendly skies of Texas USA!
You picked a winner in the Mini. Don't be put off by its small size and low price. It's a high performance quad with a great camera.
Just be careful flying in high winds. Read the manual, and practice lost drone recovery. Believe me, your Mini will crash several times, and and sometimes get lost. Don't wait until that happens to learn how to recover a lost drone. I don't own a Mini, so I can't offer much advice on storage. I'm glad to see that a few of our members have answered your question.
Lots of neat stuff to shoot all over the UK. Whenever you need help, there are over 100,000 of us here to provide guidance as you grow as a pilot and photographer. Just ask!
Glad you've joined us!
