I must choose betwen him or Mega ZX21 DSII, two engines with a similar price. Which one is better? And why? Could you comment?

Sorry for the inconvenience caused

I never run the S721P but if my understanding is correct, they are the entry level of nova base 21 on road motor. The hobby shop did tear apart the motor, it comes with a unbalanced crank shaft and tABC p/s without having the micro cast coating. You will not go wrong with a Nova base motor but I think S721P will not as fast as the Zx21 DSII. in 1/8 scale, I only trust nova base line motor as they are the longest lifespan. Good luck
