Hi, can anyone give me the real reference of the propeller that suit this kind of motor. the propollers should be a squared hole.

never seen one with a squared hole.
They are normally round.
Props are sized by diameter and pitch depending on power and thrust required..

EDIT
i forgot they are handed as well , clockwise or anticlockwise.

In what way is this a programming (or even Arduino) question ?

It is unusual for brushless motors to have square output shafts and the photographs plainly show round shafts.

I looked.
What was I supposed to see ?

The round holes in the propeller.

The round holes in the propeller.
Yes, I know that props usually have round holes in them to match the round output shafts of brushless motors, as noted in my reply #2.

It was you that said you wanted props with square holes and posted a link to motors with round shafts.

I'm not OP. But in the future I'll ensure I clearly include <sarcasm> tags.

Although most props use a round hole I believe some DJI models have flattened sides. It looks from the picture that these motors are for the DJI type props (not the standard round hole).

Like these for example..

Standard props with a 8mm round hole should work too they just wont lock as nicely.

After helping my 12 year old nephew assemble a model of a WWII B24 and we were admiring our handiwork, he said "wow, those old planes sure must have gotten hot when they flew".
"Why do you say that?", I asked.
He said "well, look at those 4 big fans on the front of it".
