  1. DS125MG, one maiden with face-plant. review by Argo on 4/20/2014

    Used two of these for elevons in a 1.8m plank. Over 6 months (it was a really slow build) I have bench-flown with them many times and although 'chatty', they always centre well and have good precision.

    On the maiden landing I face-planted and flipped the wing over on to the elevons. This broke the supplied nylon servo horn but has not affected the servo (as far as I can tell) at all. I guess that's pretty good evidence that these servos can take a knock!

    Highly recommend getting the ply servo-frame as well. These make placing the servo much easier and they are a nice cutout template too.

    (Note: Like most high end digitals, these will not tolerate poor connectors or bad solder joints. this can contribute to servo noise.)

  2. Best servo for money) review by soarer on 8/9/2013

    Bought eight servos here and use in my two F3J planes. Amazing servos, perfect centering, high torque! Plan buy more in future and hope for same quality.
