Trex 600LE Tail servo overdrives HELP

[gaffuri]

hi all, I just completed the build of the 600 LE today!!
Set up finished too but with one worring issue
Everytime that I switch Tx and then rx on the gyro overdrives the Tail servo (620 Align) until the radio binds. After then everithing is ok and the tail servo works within the set limits.all the other servos are not moving till the rx is bound, only the tail one!!
What can I do to correct it???
thanks in advance for your help

Rebind the heli

Thanks, Just done it but it still overdrives the servo....I am confused

Are you on Spektrum?

[gaffuri]

yes, DX7 and 7600rx

align 780 gyro ??

The gyro should do nothing until it sees a signal from the RX (after bind)

Sounds odly like you've got Gain and Tail in the wrong channels but I can't explain how it works at all like that.

Check your tx monitor and see what channel is moving.

Check your tx monitor and see what channel is moving.

Won't show anything useful if before bind.

I have tried everything today, rewiring , resetting the radio and rebinding all over again with no result.
I tried a different servo and a different receiver, no change
It must be the 780Gyro....
no other ideas?

Now you say its the 780 theres a good chance its that.....slap a qaurk on it or a gp750

[gaffuri]

thought the gp780 was superior to the 750
did you have problems with it before?
