how to find the pitch of a propeller,I done one example but did'nt get it right ,there r many other details in 'electric R/C plane' section in this site

Is this the right way to find the pitch
seniors advice needed

Why do we require to find the propeller's pitch ?

One knows the diameter and pitch while buying it. Also the dia & pitch are mentioned on the props.

hai,Ashutoshn
  What will u do if u get a propeller with no pitch written on it. just kidding

I would ask the person from whom the prop is to be bought.
