All my drones have black propellers. Being a newbie, one of the hurdles is orientation when the drone is facing different directions. I know "headless mode" is the solution. However, I don't want to use headless mode all the time. I am thinking of spray-painting the 2 "front propellers" with different colour so that I will tell which part of the drone is the "front". My question is : since paint is added onto the front 2 propellers, will it cause "front heavy" balance issue ?
