this may sound odd, but i have 3 silver and one gold? Looking down on the craft, the front right and rear left shafts are the ones marked with a white circle, so installed 2 silver tipped propellers with the small white circle in the center. on the other two i ended up with a gold tipped and a silver tipped, both without to small circle in the center. Is this normal that they are not color coordinated?
