ReactionRC Bullet Connector Caps are insurance to easily help prevent blowing up your speed controller. These snap on to 5mm low profile bullet plugs (and 4/5mm combo plugs) to clearly identify the positive and negative power wires. Red and black coloring and polarity markings on the tops. The tapered shape improves grip and makes plugging and unplugging the wires a snap.

Auction includes THREE pairs of Caps (3 black and 3 red). Low profile connectors are sold separately.
