Settle down Mr Perth.
As figures have yet to be published, I draw the assumption that the B210 with have an AEW of around 2300 - 2500 kg with a MTOW of around the same as a B412, lets say 5000kg in any case.
That allows a nice payload of around 2500 kg......now that would be over twice [3 times a 350] what any light to medium can do now.....
But of course the figures are not yet published.
