Hello, im new to this forum so im sorry if this guestion has been asked and answered before. What is the performance differance in a 2 blade and 3 blade prop the same size? What im looking at is the x440/3 blade, a guy on youtube has this prop on the same boat i have and it is realy fast:banana:. Since i dont know how to sharpen and balance metal props the x440/2 blade will be cheaper to have balanced and sharpened. Thanks for any and all help.

With an additional blade, you increase the loading on the system. Accelleration can be increased, as can "bite", which helps the boat get off a corner. Top-Speed may or may not be reduced. Lots of factors involved.

Thanks Darin, i think ill go with the 2 blade prop cause i dont want to overload the motor and esc, i have a plastic prop 1.4x40 and im happy with accelleration and top-speed and i think the x440/2 blade will do just alittle better. I just wasnt sure what the 1 extra blade increases. Thank you.
