Please help me I AM A BEGINNER
Unfortunately that’s far too specific an application, and actually requires quite an investment. You can follow this series and select a frame, motors, propellers, ESC and battery which are able to lift quite a heavy load (chemical in liquid format as well as the container). You’ll quickly find that in order the lift an additional ~10 pounds (not include the drone and its own battery source), the cost of these parts gets quite high. If you are a beginner, you should not aim to immediately create a ~25Kg multirotor drone and instead work on a small to medium sized drone to help you get experience. One small error in the settings, a propeller connected the wrong way, or a weight imbalance means you can lose your entire investment.
