Stable income: Somewhat stable

Drone rental can be a moderately stable source of income for most people who try it. Based on online sources and my own experience, some individuals consistently earn from this side hustle, while others may experience fluctuations in income due to factors like demand and competition. If your best friend quit their job to do this full-time, it would carry a moderate level of risk. I'd rate it a 3 out of 5 because while there is a decent baseline of income potential, it may not be as reliable or predictable as a traditional job.
