Put a new propeller in paramotor


Recommended Posts

The propeller must be suitable for the particular motor.

Specifically the fixings: number and size of bolts plus diameter of the circle that the fixing holes are on in mm, example 6xM6x50

The pitch of the blades has a big effect on performance and must match the characteristics required to suit the power output and the redrive reduction ratio.

The gap needed between prop tips and the cage is very dependent on the resilience of the engine mountings, you can have a smaller gap if you have stiffer mountings.

Have a good push on one of the propeller tips and you will see how much deflection can be achieved.

I'm suggesting a minimum gap of 5cm, others may disagree.

Hope this helps,
