Welcome to the forum. I have a PV2+ also & I use the same maintenance on it. I keep the shell clean & check for any cracks, etc. Monthly when flying a lot, I make sure the screws are snug. As far as props, if they are not damaged, nicked, or any visible problem, you should not need to change them, Unless, the center Hub gets worn (the hub on the P3 is plastic unlike the PV2+ which is metal). With regards to the motors, they are supposed to be very long lasting, several thousand hours. Just check them before flight to make sure they spin freely with no binding. Good luck & enjoy your new quad.
