FPV and Quad handy wrench

thingiverse

This utility has been crafted with the intention of providing a convenient solution to tighten racing quad props nuts and Video antenna SMA connectors quickly and efficiently. The open side is specifically designed for antennas, while the closed position features a 10mm exagonal wrench that's perfectly suited for racers' motors. I've found this tool to be an indispensable addition to my field kit.
