    Sounds like it may be a power supply problem I don't think its getting enough voltage.
    Typically, the larger the motor, the slower it's max usable rpm
    Not sure off all your switch settings on the driver, but I would check switch 4 from reading the pic that can cut your voltage in half or allow full voltage.
    Hope this helps
    Cool looking setup :good: good luck
