Hi, did anyone see some shuttlecock serve machines? I saw the machines which are used to serve in tennis and pingpong, but never see the familar machine on the badminton court. If there's no such a machine for now, why there's no manufacturer make it? I think a good serve machine might be very useful to provide a tough training for a single person. Also, if it's computer-controlled, the training should be perfect if the coach is in holiday! Does anyone have any idea about this casual question?
