Aa777888: that would be a image from the official website, check it if still unsure. They seem to have changed the specsheet after that. I'm glad if they get it certified for 900kg mtow, that means quite the difference in payload.
But I'm not too confident 900 will be the deal, you can still see the 450kg in the .pdf specs, also this marketing speech confuses me :
The turbo-shaft engine with FADEC electronic control system,provides 250hp to obtain a helicopter with the best balance between power and weight in the world with less than
2 kg/hp at maximum take-off weight.
450kg / 250 hp gives 1.8, do the same math with 900kg and you no longer have a world record.
