Hello, I'm trying to figure out if I should buy a new 17.5 or just replace the rotor. I have an older Maclan 17.5 and it's slow compared to my Team Powers motor. It also has little to no torque. I was wondering is buying a new High Torque rotor for the motor would fix it's speed and torque issues? It's only like $35 for a new rotor vs. >$100 for a new motor. This is 2wd buggy.

Thanks!
