That is true but you need to match the right prop to the engine and airframe. If you come in to a forum asking for help then to take the advice given to you then do come and ask for help.
Again as three peopl have said that isnt the right prop for that engine and airframe. From what you stated in here it doesnt seem you dont know how to set up pipes for planes either. I am not trying to be mean to you but only help you.
