RE: best motor esc combo
What kind of battery to plan on running? Voltage makes a significant difference in the top speed. If you can run a 3S lipo, that 35T motor is quite speedy. I would definitely stick with the FXR ESC regardless of what motor you choose. It's small so it's easier to cram into tight spots. I use a 27T stock motor in SCX10 on a 2S lipo and it goes about as fast as the Wraith RTR, but a 3S lipo with a 35T motor is faster.
