Replacing propellers.

[TimMc]

I left my first set of propellers on for a year. Finally (?) got a warning about propeller drag and replaced them.

After some google search I find DJI recommends replacing every three months. I am hoping for some insight/suggestions on what works in real life. Thanks

Any thoughts you guys?

How could anyone recommend a time interval without knowing how often the props are used, or more accurately, how many hours of flying are on the props. What drone do you have? Have you inspected them and compared them physically to new? Bottom line is that props are cheap so just replace them.

I knew I forgot someone! Sorry Jeffrey, glad you saw this.

From a mechanical standpoint I know replacements in Industrial settings are based on hours normally. So I agree, it shouldn't be based on a set time, since perhaps it's only been flown once or twice in 3 months is totally different then it being flown every day.

Thanks for the replies. The drone is a DJI Mavic air. Visual inspection showed nothing wrong but after replacement the drone feels a little quicker. The sensors on the drone are no longer kicking out a drag warning.

On a better note I also changed out my cell phone to an iPad connected to the controller. Great improvement.

I only changed my props after crashes, so haven't felt any need due to age.

That's interesting Tim. It could be they have worn out some enough to affect performance but not enough to be seen visually by eye?

That is my first guess. Second is that the bayonet mount wears and produces a small wobble. The third guess is that DJI program kicks out a warning based on hours of use. With my iPad attached I have explored the program more and found it logs all my flights, flight times, distances, heights and maps each flight and locates each picture taken on the flight map.
