Was delighted to receive your X-PACK 1 drone as a holiday gift am anxious to take it up for first flight!
Would make one suggestion though, before I do.
The translation to English in your Operations Model booklet is "choppy" at best.
And can be a bit confusing to your users.
Example "To disassembly, press the battery buckle button, and pull back "
More clarity in English would help assure no accidents for your users, both young and old.
