Just purchased a P4 and after just one flight I am delighted with the purchase (have previously owned P2; Inspire 1 and P3 pro- Definitely best so far but I wish DJI would stop bringing out new models - ha ha!!!) Only problem I'm having is that it's almost impossible to get the battery out of the P4. I press the top and bottom buttons as hard as I can and can't get enough grip to get the battery out. Only way is to get my wife to hang onto the P4 and then I use a finger nail on my left hand to pry it out. (I don't really want to use a screw driver because that will scratch the P4 and battery.) It seems to slide back in ok - just a problem with the last 10mm where the clips are. I have not had this problem with any of my other quads. Is anyone having this problem and if so have you a suggested solution or technique to help me out. I have read some earlier P2 & P3 threds where owners have suggested to wipe a thin film of silicon on the battery but I'm hesitant do do that.
