Change Propeller

Oh, I'm sorry! This model (https://grabcad.com/library/uav-drone-plane-1) downloaded more than 600 times And no one made me notice that this is not the correct propeller. The propeller that is will be drag, but you need a propeller which is TO PUSH !!! I put ashes on my head. I have to correct the mistake. This is the right propeller for this aircraft.
