Default Shaft bent easily

Hi

I recently bought a 28x30 mm size brushless outrunner motor with 3.17 mm shaft diameter. After the first two flights (with a slight hursh landing) I noticed that the shaft is bent easily. Since I am not very familiar with outrunner motors I wish to ask whether this is a common problem with brushless motors. It really is a small shaft ( I used the not rotating side to mount the motor and used a prop adapter not the prop saver included). Does the propsaver save the prop really or the shaft from bending?

Thank you

Yes, prop savers work. I've used it many times and it probably saved me from having to buy a new motor. The problem with them is that they can be kind of tricky to work with. If the o-ring that holds the prop on breaks, then you will probably lose your prop (I've done this and watched the prop just keep on spinning and flying away). I also found it difficult to find a way to mount the prop onto the prop saver. I have an AXI motor with an "E" series prop from APC. Those two just don't like working with each other.

But, overall, I think they are great for someone, like me, who tends to land in awkward ways.
