    Quark BLS251 Setup

    Hey Guys

    I'm helping smokingtommy setup his Quark gyro with a BLS251,

    He had changed to a Quark as the Futaba 520 started drifting quite badly after checking most things over..

    Anyhow.. during the setup.. We change the servo to a BLS251, and set the correct parameters, But when we connect the tails servo, the servo wants to go bad.. and the servo arm will go back and forth like a tic toc at blur speed... Obviously not right.. We had double checked and rechecked that it was set correctly.. and we had even changed it to a S9256 as that is a 760u servo, But still the same effect..

    Any ideas?

    Regards
    Callum

    You set the correct frame rate?

    What machine is it on?

      Framerate is set correctly..

      It's on a Kasama Srimok 90n

        sounds like the framerate is wrong as paul suggests.

        2 flashes is what your after on servo setup menu.

        cheers

          have you got the gain maxed out per chance?

          assuming not try a non 760 servo on it (any digi will work fine for test) and see if behaviour is same.

          cheers

            We are using the Quark Software to set the gyro up.

            We double checked the gain, we have the ATVs set to around 40%

              Think we may have found out the problem..

              Battery is low. lol

                  Hi There,

                  Still the same issue, However, It is intermintant.

                  It will only seem to happen when we connect it to the software and move one of the end point sliders or make adjustments.

                  Although it seems to be fine when not connected.. I consider this not flight worthy until the software and servo function correctly.

                    Yeah keep it on the ground till your 100% sure it's working correctly.
                    Have you tried to set up using only the LED?

                      Works fine with the flicky led method..

                      It only occurs during the software connection method.

                      We have picked the helicopter up, shaken it violanty etc, tapped the gyro, wiggled the wires..

                      as i say,

                      It only seems to happen when we connect it to the software and make an adjustment.

                        i'll try one of my own quarks tonight if i can with the same servo and see what happens. never seen one do this so will have a nosey.

                        is it only when you adjust the end points it does it?

                        i adjust the stop gains quite often with mine and never seen it do this with same servo-can you adjust the stop gain and it does it?

                        cheers

                              i think you need to understand what your seeing in that video-that is oscillation which is self perpetuating.

                              i think that is perhaps all you are seeing here-very common with the bls251 i should add.

                              if you take the gyro off the airframe and move the end points will it do it?

                              cheers
