Does anyone have any suggestions about steps to take to reinforce drone arms on P3S to help prevent or prolonged cracks from starting around the screws. I have read so many posts about this dreaded plague that I am scared to do much flying. I am new to drones and started with the cheapest Phantom I could learn with the Phantom 3 standard. I would like to stick with this particular series and move up as I gain experience but if the shell cracking is a big problem I am weary of this. These birds are expensive! Thanks for any input.
