PDTXCLS OLSAinny Sudopo Andwing Spedix Quad Wrench w/One-Way Bearings

This convenient little tool fits in you pocket or a corner of your drone’s case, and tightens/removes propeller nuts. It ratchets with the smoothest one-way bearings I’ve ever encounteredIt just works, and it doesn’t take up much space. Get one if you need to put propeller nuts on your drone, especially in the field.

Best way to remove props by far.
