# How much weight a drone can lift/carry?

i’ll be constructing a drone attached with a robotic arm. How to determine the maximum weight a drone can lift/carry given it’s drone frame size, Rpm/V of motors, etc. Is there a mathematical formula in solving this problem? I will be using 250mm drone frame size, 2300KV Brushless Motors, 5″ props how much weight will it be able to lift/carry?
