Hey everyone. Last time I made a post here I was flying the P2V+. I have the Phantom 3 Pro now and I'm in a bit of a quandary. Somehow I've cracked the UV cover glass. I've ordered the replacement and I have it now but for the life of me I can not unscrew the original. I have even put some vice grips on it to no avail. Is it supposed to be this tight? Has anyone else ran into this issue? I'd be grateful for any advice.
