Also there is no way this is going to be legal to drive on public roads in most countries - just look at the massive tail boom that sticks out. This is just a fancy aircraft for people that want an overcomplicated Cessna.
Poor ergonomics is actually a large reason why I sold my Deck. It is quite heavy and clearly made for hands bigger than mine, which made holding it for more than 20 minutes quite uncomfortable. Also the joysticks are just awful, awful, awful awful awful. Id say a hall-effect stick mod is basically mandatory.
