First off, how do I tell which version of the Phantom I have? I know it's a v1 but others are mentioning 1.1.1 and I don't know whether that applies to mine or not. Secondly, people are mentioning installing the self-tightening P2V props on their 1.1.1 Phantom, which I'm interested in if mine will support that. My props have the holes that are keyed with flat surfaces and the prop nuts all tighten in a clock-wise direction. Will P2V props work with mine or not?
