Are these props safe to use?

[cheddarman]

I bought four spare props for my P3A from a well known auction site. They were advertised as suitable for the Phanton 2 and 3. On arrival they have a metal hub which is bigger in diameter than the plastic ones from DJI but the threads are correct and screw onto the motor shafts all right.

Are these safe to use on the P3A or could they come loose?

They were advertised as suitable

That's a phrase often used when people are selling 3rd party props.

Are these safe to use on the P3A or could they come loose?

Yes, they could come loose mid-flight. Will they come loose? There's no guarantee they won't.

Are you an MP by any chance msinger?

 

[msinger]

Maybe. What's an MP?

 

[cheddarman]

Ah, sorry, politician
I complained to the seller for "not quite true" description and location and got a refund - and get to keep the props!

 

[msinger]

Ah, no. I'm not politician.

It is generally regarded that the plastic hub props basically self lock better and resist any torque induced unscrewing in sudden / quick stops.
The metal threads being more precise can lead to unscrewing in that quick slow down / stop.

I always refer to something a Captain told me when i was a Junior Ships Officer .... If you have to ask if its safe - then assume its not. You will never regret it.
