FPV

FPV flying with racing drones has fascinated me since the first time I saw one flying. It's probably the closest hobby to real flying without having to sit in an flight vehicle. (As many times as I've flown into a tree, it's probably better that way).
The speed and precision with which these drones can be flown is simply breathtaking.
Here's a video of me dancing with some treetops  :)

Sailing

Sailing is my oldest hobby. I have never sailed in regattas or anything like that, I prefer to wait for the next storm and then almost fly across the lake. Here is a video of a friend and me ripping the lake.
