Prop selection - Tecnam Golf

[Willborne]

Hi All,

 

I'm looking at replacing my wooden prop on a Tecnam Golf with a alloy or carbon fibre type. Even though it has 24 rego there are a number of props that have been approved by the manufactuer.

 

Can someone advise the benefits (if any) of a 2 blade as opposed to a 3 blade prop?

A three blade prop is quieter. The story doesnt end there. A two blade prop is more efficient than a 3 blade prop but at a lower power setting. If you increase your power then the 2 blade prop becomes less efficient untill you reach a point where putting on an extra blade is more efficient. If you increase the power more, then again you get more efficiency by adding blades. Basically all this says is that the prop needs to match your power and that putting on a three blade prop can give you less thrust or more thrust.
