I bought the align flybarless conversion for my 600. Everything seemed to be working well until I got to the setup for the tail rotor. I am pretty sure I have everything plugged in properly (the rest of the cyclic and collective settings are working fine) but I don't get any response at all from the rudder. I can flip the gear switch up and down (the aux that changes from heading hold) and I get the status light to flip from red to green.

Just to make sure I wasn't crazy I hooked up just the rudder servo back to the original tail gyro and it responds perfectly so I know the TX is sending a signal, the RX is getting it and the rudder works.

It is a futaba S9256 that came with the GY611 with a voltage step down.

Any ideas?? Thank you!

P.S. I even got a seperate 3G box that came with my 700 that I've never used and the same thing is happening. Using the rudder TX stick seems to just bump the servo a little bit when I throw it full right.

you need to set it to 760 usec.
see the 3G manual on steps for setting 760

OMG. Thank you. I thought I had been doing that step correctly - I would throw the rudder stick until the light changed from green - but it was only changing to orange. I threw it three times and it went to red and now everything works.

I spent three hours trying to debug everything from a burned out servo to damaged connectors to just learn the difference between red and orange.

Thanks! This is one of the reasons I love this site.
