I have no experience with the 70 mm medusa, but it should perform close to a 1515... Now I do have experience with the kb45 motors, and considering you will be water cooling the motor I would go with the kb45xl, maybe the 10xl-11xl on 10s a123? Big motor, with big power! I ran a 1/8 on road car geared for 50mph with a L can kb45 and it performed very well, at least as good as a 1515, so the xl should perform as well as a 1521. They are 2 pole motors, and they will not run as efficiently as a neu, but water cooling will keep the heat down, and you cannot beat the price, get 2 for the price of that 70mm medusa, and it will put out more power. Hope those a123 cells can handle it... Maybe go 2p (use all 20 cells).
