    It costs $200 for the motor and $15 for the adopter.

    Eagnas (www.eagnas.com) and ask for Vistor about the DC Motor for badminton.

    He has to replace the motor controller chip inside the motor that appliable for badminton.

    Enjoy

    Can you confirm this is constant pull? Could you upload a video? After hearing so many bad things about eagnas the last thing i want is some of their electronics. AND ask them to modify/change part of them as well. I am skeptical about it being cp because I was informed its just an electronic pull/lockout.

    What is the difference between constant pull and pull/lockout ?
    Thanks

    It's an awfully long way from the racket to the tension head; being totally OCD about string wastage I'd have got it as close as physically possible to the turntable, but if you don't pre-weave it shouldn't be a problem.

    Does the racket grip clear the tension head? Looks like there's interference in the picture (and given the size of the grips on some of the rackets I string...:D).

    constant pull - continuously maintain a pre-set tension even as the string stretches due to natural deformation during the tensioning process.

    lockout - simply stops pulling after it reaches the pre-set tension, despite that tension loss is happening due to the natural deformation of the string.

    constant pull is better because it results in less tension loss and more "true" a tension.

    So If we do manually pre-stretch the string and pull with this lockout device we might be able to maintain the tension closely to the pre-set, right.

    in theory. it depends how good a job you did.

    alternatively, you can try to pull twice. pull once, lockout, wait a little (use the time to weave the next string) and then tension again.

    That's correct. I may add that the OP pull once and clamp the string with a flying clamp. String one ahead and pull the second time. The key is to know when to release the flying clamp when tensioning for the second time.
