    Servo Jitters and Overshoot

    Gd evening all,
    Currently now fixing my 380 heli. All went smooth until setting the tail servo. Using a KST515MG HV at 6v with Mini VBar. Servo pulse width set to the same category as 9254/9257.... But having jitters and overshoot at some point. No fine tuning at the moment, all electronics are new. Any input wth regards to this is appreciated. Thks for viewing

    If it overshoots and bind, then your centering pulse freq is wrong unless I mistaken your symptoms.
    Too many helis!

      Tail servo frequency are at 15000us/333hz, should be the same as a 9254/9257. But when I plug directly to RX no such occurence. The servo wires that came with it is too short, change to 30cm for easier routing under tail servo tray. Any recommendation from goblin 380 flyers?

        Well I just settled my issue with the tail servo. Turns out that
        my BK tail servo was wacky. I routed the wire through the gap
        between tail boom & carbon frame. Re tail servo do you hear lots
        jittery sound & when u move the rudder stick does the servo moves
        smoothly ? My didn't & when power up the heli you see the servo jitters.
        Change it & all is fine now

        Cheers

          Well Sumo, it's likely that my tail servo is bad. As I did a lot of test on it but same result happened. Any recommendation for a servo of the same specs and price?

            Servos hard to say look even my BK had issues.
            Maiden yesterday & no more issues.
            Have 2 frens flying clone 380 & they did mention
            that the ALRC servos are working good. Perhaps
            you can take a look. For me it's my first small
            Goblin so can't really comment much but my
            take has always been, Never Cheap Out On
            Electronics. Besides Sab spares aren't cheap
            to begin with.

            Cheers

              Honestly, flying an Alzrc 380. Where did your buddies get it from?

                I live in Batam for now. There's a shop here that imports this brand.
                Think its www.planetheli.com
