I haven't heard of any issues running the Tekin 17.5 motor. I actually ran a Tekin 17.5 if I recall correctly with the SP GT2.0 Pro back in the day on both 1S and 2S usage so I believe you should be fine.

If the MMM is too much money, there V3.0 motors are available for a good price new, I believe its like $60? The really nice thing about the motors in addition to how they perform is the fact that they have that plug setup. Really makes changing things out a snap.
