Ok I just got my Turbo Vee boat today and am very impressed by the build quality and workmanship. But it makes this fairly high pitched sound from the motor any time it receives a forward or reverse signal, even a slight pull on the trigger that doesn't make the motor run will cause it to make this sound. It was making this sound constantly out of the box until I trimmed out the throttle adjustment on the controller, now it's silent when it is just sitting there. None of my rc car motors have ever made this sound so I was just wondering if it was normal.
