hi all , my unit now goes nuts when i plug it in and by this i mean the servos go in all directions and bind.....any ideas as to whats happening ?

Cheers Chris.

Hi Keeny,

can you describe the problem more precisely, please?
From which point it started to happen? Was there any change in your setup or settings? Can you connect to the unit with PC or other way?

What is your receiver/transmitter?

Hi, i can connect to pc but without the servos conected. I was messing with giro settings as my rudder wouldn't hold very good in normal flying .
Then the servos started going in all directions one up two down then go to far and start to bind.
This happens every time i plug it in.
Its 550 dfc with nomal spirit.

Futaba transmitter and using sbus.

Thank you for the details.

I recommend to return the gyro gain to the previous value and start again. Or you cn try e.g. 50% (AVCS). So just to return back in the same way as it happened.
You can also recheck if the Receiver type is still configured to Futaba S-Bus in the software.

If you can't still connect with all the servos then there are possibilities:
a) Because of erratic servo movement BEC is restarting (including the unit)
b) There is some issue with one of the servo (you can try to connect servos one by one to determine if it will work with all, but separately - only one servo at the time)

But first the priority is to resolve erratic servo movement. Do you see a strange stick movement also in the Diagnostic tab?

Its impossible to set anything up or check settings, as soon its powered up it happens .
I tried loading a saved settings back in but still the same.
I can't use software with servos plugged in......
Ok so far used rx batt and still the same then plugged one servo in at a time and on the third one channel 3 it started to go erratic again.
I'll have another go tomorrow.
Thanks for your suggestions.

You are welcome.

You can check the settings at least without servos.
I recommend to not use a battery instead of BEC. If there is something wrong, then it has much more power to burn something.

Also it is important that S-BUS adapter is connected in the correct way, but if you have not did anything with wiring, then there should be no problem.
