I recently purchased a Mavic Pro Platinum fly more combo. It came with 2 silver tip propellers attached locking arrows pointing cw. The accessory kit had 1 silver tip locking arrows pointing cw, 2 gold tip pointing cw, 3 silver tip with lock arrows pointing ccw, and 2 gold tips locking arrows pointing ccw. The blades on the ccw propellers have opposite pitch angles. What's the difference between gold and silver tips, and is there a logic to installing the correct blades. Was I shorted 2 silver blades.
