Prop rotation
« on: October 19, 2014, 07:06:09 PM »

Hello
 
I'm going to be building a twin screw motor cruiser with contra rotating props, does it matter weather the props rotate inwards or outwards?

Hi,
I have found that model performs better on twin screw and twin rudders if props swing out board.
