    Do you guys actually pay vat / taxes on full price? Normally sellers in China can write like 1/5 of the price on the declaration.

    QS 138 70H with Gearbox

    Is this motor using 60° or 120°Hall sensor phase angle? I hate that the information about QS motors are so limited.

    The motor mount welds look more like my type of welding :lol:

    Voltage selection

    Lower voltage will give you less speed and torque. At some level it will be too low to even spin the motor. I'm waiting for my QS138 as well :) Did you get the QS138 v3 with internal gearbox?

    Yamaha YZ250F

    First of all great work! How important is it that the motor is completely aligned? Does a small angle make a big difference? My build is starting in a month and I was hoping to weld the mount since I dont have access to a CNC. Guess alignments will be a bit tricky.
