By all means, visit Germany. 2 things: You need a fire-resistant tag with your name and address on your drone, and liability insurance is mandatory.

I use a smartphone to monitor the drone. The close flying must be practiced, but is easy enough. I wasn't really THAT close to anything as it was very windy.

Prop guards are super to protect on the sides. The only problem is wind between trees. It can lift the Spark by 50 cm or so into the foliage, in which case prop guards don't help. Knock on wood, so far, I haven't crashed it even once. :-)
