My next build is the Gaui 255 converted to an X2 FES. I'll be using a Tarot ZYX in it. I've started a thread about it here:

Hello
I have a problem with the Tarot ZYX. I have hard coded tail servo 960us digital. After you turn on gyro does not work the tail to one side, starts to work after connection via USB to the software. And AVCS Mode works as in Normal Mode, return to the Center. Do you know where to get the Firmware?

Thank you very much

today new 3 flights with raptor 550e.
Finally i received the usb dongle, so i was able to setup all parameters. And i correct deadstick first to 10 (but to every pitch movement hely climb immediately) later to 20 and finally to 32.
I reduced a little gyro in all directions. But as i tried to made my first loop, the ely stopped in inverted and started to go down.
The problem was too little end point movement for elevator.
Solved increasing form 32 to 45. But now the problem is that is agin very sensible on elevtor! so.. no soution for the moment to my sensibility to elevator.

And every time i try to land the last part of approaching is really difficolut cause when i m near to the lower stick, the ely loose height very fast and bumb on the ground. Well, probably this depends form incorect motor curve (i Think). but is not a big problem. The first one instead is not so good and i need to solve it.

in every case i m happy again cause at the end is the 12th fight i do and is reaaly simple to manage.

oh and another question for you all: i noticed that my lipos has less flyght time with respect before using the tarot.
I m using 6s packs with 5000mA 30C.
Before FBL my flight time was 7-8 min. Now is less than 5min. Is strange cause when i charge batteries they are efficient and charge completely to over 5000.
So is the unit that drain a lot of amperes?

It does drain slightly more mah, but it shouldn't matter minutes. It's like running an extra servo, it doesn't come for free but it surely doesn't cut flight time in half.

Perhaps you've become simply more confident and fly a bit more aggressively now?

What are your settings exactly? 45% for end points sounds by far not enough for normal control if that's limiting the actual movement of your servos.

It could be that the gain has to be lowered. Don't think in numbers, but think in what values turn out to work in practice.

My settings are:
PitchAgility=40
PitchGain=32
RollAgility=40
RollGain=32
YawAgility=30
YawRight=30
YawGain=70
[section2]
FixMode=1
ServoType=2
SwashPlateType=5
ServoDirCH1=-1
ServoDirCH2=1
ServoDirCH3=1
ServoDirCH4=-1
ServoAdjustCH1=0
ServoAdjustCH2=14
ServoAdjustCH3=21
AileronLimit=32
ElevatorLimit=45
TotalCoefficient=-53
PitchDir=-1
RollDir=-1
YawDir=-1
TailPoint=-19
TailLimitA=62
TailLimitB=20
OptimizationDir=-1
[section3]
Acc1=120
Acc2=40
Acc3=125
Acc4=125
Acc5=20
Acc6=20
DeadBand1=32
DeadBand2=4
DeadBand3=20
DeadBand4=4
PitchGainD=20
PitchGainI=100
PitchGainP=80
RollGainD=20
RollGainI=100
RollGainP=80
SpinSpeed1=30
SpinSpeed2=30
SpinSpeed3=40
SpinSpeed4=40
TailCompsate1=0
TailCompsate2=0
TailGainD=25
TailGainI=40
TailGainP=80

But probably i Really need to lower gain. Next time i ll try.

I would also try to confirm what those Acc values are supposed to do according to the manual, because that might be an 'acceleration' value per servo channel.

Also take a very good look at the ElevatorLimit and AileronLimit. Those values seem far too low to me.

Pitch Curve and Throttle Curve


I am going to setup the ZYX soon. I have one question though: after setting up the ZYX controller, am I going to setup the pitch curve and throttle curve using the same steps as for the Flybar heli ?

Thanks,
