Hi guys, I am setting up a heli for a family member and i am stummped. Its a trex 600n pro and i am installing a 3gx on it, here is the problem. i have all the cyclic servos (Futaba S9451) working fine, but the tail servo (Futaba S9256) is not doing any thing at all. its not even humming, I know the servo is good, any advice, Oh i am using a DX7 also. I have set up 3GX fbl stuff before but i am confused. any advice would be great

watch me fly this, don't worry, read the book that came with the heli!!

Believe that is a 560hz servo. You probably need to change the tail servo type. Program 3gx for narrow band tail servo..

Change the 3GX to 760us tail rotor neutral pulse width, leave the swash servos alone and finish the setup. It will work just fine with the servos you have.

^^^^^^What Dave said.^^^^^^

Tail servo setting is separate from cyclic.
