9540 vs 9540w Propellers

[t2adze]

Hey

Want to ask you. i am having black props which are 9540w models. I decided to change my grey ones, due to their thread damage. So i took 2 from my friend. Brand new ones. But they say they are 9540 (no W model).

Is it ok if i fly with 9540w black and 9540 gray ones together?

Did you at least read what i wrote?
All of the props are new.

First of all, yes I read what you wrote, you said "I am having black props which are 9540w models" I assumed you meant you already had black props which are 9450 models, you never specified that they were new either.
let me be more specific, get another package of props so that you have all matching props. It is $6, better to be safe than sorry.

I believe the 'w' props have metal hubs???
Or do I have it backwards?

Either way do not use metal hub props on the P3. They are for the P2s.
Only the composite hubs should be used on P3s as they are intended to provide more security with the motor braking feature.

(FYI: The opposite is however OK. i.e. Composite hubs on a P2 is just fine.)

+1... I would also recommend getting a new matching set of props. It is just too much risque for such a cheap and very important part.

If the ones you have are new, get more props to match them.

Ok thx.

But what is the difference between those two?
