Caliber speedworks is a Trinity brand motor. Trinity brushed motors are generally made by epic, a good motor manufacturer. They come in 16, 14, 12, or 10 turns. I'm not sure how well the super rooster will handle them in parallel if they are 12 or 10 turns. The specs claim "no limit" for turn limit on the super rooster. That said, if you go with a parallel setup, check the temperature of the motors and esc often the first few times you run it. If you have no problem with overheating the first couple of runs, you should be good to go.
