After hours and hours of researching and trying i found solution in opentx (taranis) its no need to use any mixes only connect 3rd rear servo to throttle ch, thanks alot on tips guys

guys one more question
on collective i have 3 analog servos
on tail i have digital does this be a problem?

[TheOtherCliff]

On output page you must be using different "banks" because you set the whole bank of outputs to a single ESC protocol.

I recall the banks are set so that bank 1 is outputs 1,2,3 and bank 2 is output 4.  If that is the case, bank one is normal servos and bank 2 is digital rate.  In that case, output 4 must be connected to the digital servo.  Move your servo plugs around to make it match banks as needed and adjust for the moving in the vehicle tab.

Of course modify this depending on what outputs are contained in what banks.

i got it
thanks alot

btw  when i start spinning motor tail servo start jerking (fast go left right) i isolated FC from vibration
is it possible because tail servo is digital but i put 50hz pwm output for him
or maybe to high PIDs?

[TheOtherCliff]

50hz PWM will work, but if tail servo is digital and faster than that, you may want to run it faster.

I would start by guessing whether jerking is random or is a repeating oscillation.  If it is a repeating oscillation, the yaw PID may be too high.

Be aware that running faster than 50hz PWM on yaw allows you to run higher PID on yaw.

it is repeating oscillation, i left default pid for yaw, if i remember well P is 600 I 1000 and D is 50

guys it is there options for put two flight modes acro and normal flight? and  change curve with switch on my tx
i check LP configurator and there is just two curve setting one is for throttle other is for colective

[karla]

The way I do three flight modes with heli is having a three position switch on the TX with three separate curves (in the tx). Then I set three corresponding modes in LP FC, for example to Attitude, Rate, Acro+. That works fine.

However, I am not sure from your previous post, if you did set up the collective curves in your TX or not:

thanks on reply
no i did not frsky taranis its little complicated i link pitch servo with throttle to have collective so if i put curve on my throttle for 3d flight my pitch servo also act like throttle

I don't use Taranis myself but maybe this video tutorial series can help you.

Thanks karla
Today i try hower but my heli start wobble whole heli little and tail alot what can cause that? to high PID? , i isolate fc from vibration, does some body can sugest PID to start with i have trex 450 class

Yes, it sounds like PIDs are too high. 

For next time, it helps sometimes if you make a video. 

[karla]

You can try these PIDs used for an align trex450 using LibrePilot 16.09
The numbers can be higher but its responsive and nice.

thanks guys i will try

I've gone through setting up a Heli with a Taranis. Can answer specifics if anyone needs.
