Thanks for reaching out!
As you can see in https://www.intel.com/content/www/us/en/support/drones/development-drones/000023272.html, the maximum takeoff weight is 1900g. Please note that this does not mean that you can add 1900g to the RTF but that you can have the RTF weight up to 1900g in order to achieve takeoff.
I hope this information helps you,
