There are many aspects you have to mind when choosing a propeller like mount, pitch, diameter, stiffness and so on. You cannot simply use another propeller espacially with these consumer drones, which cannot be modified a lot. Usually there are some alternatives but most of them have a pretty poor quality. As far as I know there is nothing outthere, which I can recommand for the Mantis.

@Mrgs1 said it usually ends up pretty bad when using non OEM propellers. I personally had very bad experiences with the Typhoon H (one major incident and one crash). Both times cheap non OEM propellers broke midair without any apparent reason.
