I’ve had my Phantom 4 pro since late 2016. It had been it storage in my home for about a year and when I landed the other day I noticed several small cracks on the landing gear. I also noticed a crack on the battery casing. Should I be worried about this? It has not impacted performance at all yet...but is that something I should be concerned about? I don’t really have the money to send it in for repair right now, but is there something I can do to keep the cracks from growing and becoming a problem?
