I was wondering if I'd see a noticable difference in the torque effects imparted on the airframe from the engine/prop combo by changing props ? I think it's called P-Factor.

I'm flying a large Decathlon with a Brillelli 46cc gasser and the torque effects on takeoff are very pronounced if I'm not smooth on the throttle. Do you think changing from a 21X8 to a 20X10 would reduce the effect ?

I'm pretty sure going from a 21X8 to a 20X8 would reduce the torque effect but would the higher pitch of the 20X10 create more "resistance" and nullify the change in diameter ?

I'm planning to order some props to try but was hoping for some guidance or predictions before I buy the props -

Thanks in advance,

Eric
