Ok so after almost 2 weeks decided to remove the prop guards. Yes it's about screws. I had the original screws in a little jar in my phantom 3 tool kit but the first screw I replaced I accidentally used one of the longer spare screws from the prop guard kit (Dji set) so my question is I immediately removed it replaced all the shorter ones and fired it up with the props off in the house. It worked fine then I took it for a short hop and no issues so Is there anyway to know if I damaged the motor yet? Or is it automatically damaged by using the one long screw?
