They sell adapters or you can easily solder different ones on either the motor or the esc. The Max10 only comes with 3.5mm bullets? Idk why but I could have sworn it came with 4mm.
Kv on that motor is too high for MT tires on the Rustler imho.
I was constantly killing the plastic spurs on my Rustler with the lockups too so I went with the Hot Racing steel spur been solid ever since.
This is my setup.
Arrma BLX100 esc.
Arrma BLX100 3660 3200kv motor.
Hot Racing 86t steel...
