Just a bit more info would be helpful.![]()
The first ones have a coil spring that goes round the motor shaft to lock the props in position. The second ones are the same as the ones fitted as originals (with 3 springy tabs). The new ones are meant to be more secure, as some people had found that that the springy tabs on the originals tend to lose their spring after a while, meaning there's a danger of a prop coming loose.
That would be my take on it.So the ones without the metal plates are better?
