Hi guys,

With regards to propellers; I've been using a 14x6 propeller with my Extra, what would be the effect of changing for a 13x8?

Actually, how do you get torque? With prop diameter? And speed with with pitch? Or isn't it so easy?

Thanks a lot,

Nicolas
With your 4c engine I think you will be happier with the 13x8. 4c has more torque and lower RPM's, therefore higher pitch is usually better. However, the best way to find out is to try the 14x6 and see if you like the performance.

When I install the .91 FX (2C) I will likely use a 14x6, though I know it also works well with a 13x8.
