The Hobbywing is not a "high end motor". It doesn't matter if the physical timing of the board doesn't line up with the corresponding marks on the can. What matters is how symmetrical the sensors are to one another. With this being a brand new motor assembled by someone putting it together as quickly as possible, you might want to take the motor apart and see if taking your time to carefully tighten the sensor assembly screws. A more expensive motor has better quality control (usually).
