[Public-List] Best prop?

[Pier-André Bouchard St-Amant]

Hi John,
 I used a 13" featherstream 3 props on Jean-du-Sud. Here for the model:

Here for the original calculations:

The biggest downside of this model is the price. The upside is reduced drag.

Upon purchase, they will adjust the blades' angle to the most efficient angle at peak power. You can adjust the angle at a later time, or ask them for an angle specific to your calculations (peak power at low rpm, etc)

I would pay attention to the propeller size and the rudder max availlabe size while in a full turn (on both sides). That is also an implicit limit on the propeller size.

Best,

Pier, #399
