I can't compare because I don't have a 1515. I can definitely tell you he'll get to the speed he wants easier with the bigger motor. With the same Kv the 1521 will have much more torque then the 1515 and I'm pretty sure that will reduce the strain on the batteries. That why I'm saying the 1521 will draw less amps then the 1515 with the same Kv.
