Increasing Payload for 3DR Solo

Hi. First time here. Before having to look around for another drone, I’m looking firstly to see if the payload beyond 0.80 Kg can be made possible. I’d prefer to keep the Solo (Brand New) but need to deliver a small payload of 2Kg over a distance of 400 Mtr at a height of no more than 80 feet. Anyone out there who can advise please…?

There’s a little bit more robust group of Solo owners and people who have done some mods to them at That being said, I think without some modifications, probably not safe.
