So, let me ask you all this...... lets say I go from a 9.5x5 to a 10x6. I have increased both prop diameter and pitch. What will the effect be on the planes performance? I understand Larger Diameter/smaller pitch = torque, and Smaller Diameter with more pitch equals speed.......... but what happens when you increase diameter and increase pitch????

Am I going to get both more speed and torque?

Thanks for all of your replies.
