I wanted to use cobra 2206 motors with a 5 inch prop on my blackout mini h quad but the slots on the 5" arm are mostly m2 with 1/8 inch holes for specific 22xx motors, so I designed this jig so that I can easily mill out 1/8" slots by aligning the existing slots on the vertical and horizontal axis on a vertical mill.

Materials and methods

*NOTE* The blackout arms can vary in width up to 2mm in difference, if the next of the arm measures about 16.3 mm in width use the Blackout_arm_jig_2mm_NARROW version of the jig.
Use your preferred printing settings to print your parts.
Mount the arms using m3 screws
