The paramotors manufacturers are using different types of drilling patterns.
4 data 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
Please note :
On some old E-PROPS models, drilling patterns 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.
