i bought this (Uxcell a15070400ux0496 10Pairs 16 mm Thread 4 Pins Male Female Panel Metal Aviation Wire Connector from amazon i know the side that goes to the breakout board need to be solder but the side that goes to the motors has a screw you have to remove to attach the wire leads. is there a clip that is made for that side or does this side need to be solder as well it looks as if its made to be clipped on
