Careful with some of those planes. I bought the Seamax, as I was led to believe it was XP10-optimised. Except it's exactly the very same version that I had already puchased four years ago for XP9. Which means I naively bought this XP9 model twice. Yes it works, but that's not the issue. It's an XP9 model that doesn't make the most out of XP10, yet X-Aviation's site clearly lacks information about what you're actually buying. Well, morale of the story: I lost 12 bucks for nothing. It will be hard for me to trust X-Aviation again.
