Run it on 12S: at 300KV it is underpowered on 6S. Pair each motor with a 12S-rated ESC good for at least 71 A peak, and confirm the frame's motor mounts match the 30 x 30 mm, 4 mm-hole pattern. Each motor ships with mounting screws and an M6 flange nut; check screw length against your arm thickness.
