PARAMOTORS PROPELLERS

 

The paramotors manufacturers are using different types of drilling paterns.

 

Four information are necessary :

- (A) : number of holes

- (B) : diameter of screws (in mm)

- (C) : diameter of the circle on which are the holes

- (D) : diameter of the center hole

Some drilling references :

- 6 M8 d75 (it means 6 holes of 8 mm diameter on a 75 mm diameter circle)

- 4 M8 d63

- 6 M6 d50

- 6 M6 d60

- 6 M6 d80

- 4 M6 d50

- 4 M6 d60

- 4 M6 d56

 

WARNING :

On some models drilling parterns are using only 4 holes on the 6 holes. It is normal and those configurations have been calculated and tested.

We have sold hundreds of those models and they are flying worldwide since years.
