    I am at the initial hovering stage and am getting rapid tail wag in HH mode (green LED) if i flick it into Rate (red LED) the tail holds almost perfectly apart from a slight drift to the left, in HH whatever i do to the gyro gain/aileron pot which is set at 12 oclock the rapid wag stays constant ?
    my settings are : DX7 swash AILERON -46
    ELEV +50
    PITCH +34
    my gyro settings are RATE +71
    HH +41
    Is this normal to be able to fly in RATE mode ? PS my gain is on the AUX 2 channel

      Hey.

      In the PC software where is the rudder lock gain slider set to? Default puts it at 70% which is too high and this cause's a wag on the tail which on speeds up or slows down with increase or decreases in actual tail gyro gain through the transmitter gyro menu.
      You will need to connect to a PC to see this rudder lock gain value and lower it to help.

      The gain pots on the main casing do not effect the tail rotor gyro gain, these are for the aileron and elevator cyclic gyro gains only.

      Another thought, how have you set the ESC to, eg. are you running govenor mode on the Align ESC or just straight throttle curves? You are better with the latter and running straight line throttle curves, as the govenor modes on the Align ESC's have also been known to cause a tail wag due to fluctuations in the motor rpm.
      Also, is your tail pitch control mechanism, tail blades grips etc free to move with no binding?

      Check your rudder lock gain value first though using your PC link.

        thank you for your response I now have the rudder lock gain between - & the red mark my gyro gain is down to 50%
        this has decreaced the rapid wag but i am now getting a slow wag feeling not locked in at all
        my mechanical set up is smooth having no friction on the tail slider or pitch arm
        Iknow my firmware is on 2,1 do you think it would help if I flashed up to 3.0 ? PS my flying is not "extreme " many thanx Stanley

          You're very welcome, alway happy to help.

          You might find you need to go down some more on the lock gain, but then increase the tail gyro gain from your transmitter to bring the tight hold feel back again.
          It's a balancing act, as I found by lowering the lock gain that in most cases I could then increase the normal tail gyro gain for a better hold.

          Of course another consideration is your tail servo horn, how far out from centre do you have the control ball? If it's too far out then you will need to lower your gains to compensate, I always run a slightly shorter distance from the centre of the servo than advised in the manual, but this then allows me a better gyro hold of the tail.
          As long as you don't go too far in, mechanical travel never becomes a problem either.

          V3 is good, some slight niggles it seems, but an improvement over V2.1. However you will need to make sure your BEC is powerful enough if you go V3, as it's known to cause the servos to pull more amps than V2.1 did.
          Personally I'd stick with V2.1 for now, you won't get any major improvements I don't think, plus I have some nice settings files for V2.1 that may make your model feel even better. I can email them to you if you'd like?

              OOP·S clicked the wrong box (happy hour here ) yes 2 clicks - and all settings chimed in 3 test flights and all control attitudes are fluid thank you once again for your time and input

                Looking forwards to the MAIDEN on Sunday. Get those LIPOS sorted out.
                Been there and done that, but never stop learning.
                Now too many Helis to mention?
