1. Use less secure mounting.. orings or a single prop saver latex band.
2.If using a outrunner with an extended shaft that protrudes past the prop saver hub you can dremel it off flush with the hub.. take care not to have metal debris enter the outrunner.. best to mark the shaft with a sharpie and remove it completely from the stator and can if cutting.
3. Use durathrust or similar heavy duty props if using slow fly style props like 8x4.3s etc,much more durable than gws but also heavier and a little less performance.
I'm using one single band currently. I think I may explore option 2. Thanks!
