I think I know the answer but I will ask if anyone has an idea. I have a 7 ch Orange receiver/gyro to put in a model that has 2 elevator servos. On Futaba, ch8 is the 2nd elevator channel. I don't have an 8th and I cannot fathom how you drive 2 servos. Tried a 'Y' lead, just means elevators go in different directions. I guess I will have to have a separate gyro unit running through a Futaba 8ch receiver. Maybe you have a better solution, I hope so!

Simon - Couple of ideas for you, using existing elevator set up & "Y" lead.
1 - Change linkages / horn position on 1 servo so they move in the same direction.
2 - Fit electronic servo reverser to 1 servo.
Trust this helps.

Too late now Simon, but all you do with Futaba is make servo 5 (or any other spare channel you choose) a slave of servo 2 (programmed in the Tx) and it will happily track (or reverse) every elevator movement. I will show you or PM you the exact setup if you tell me which Tx model you have (it has been an available feature since the very first digital Tx futaba made), and every model I have has dual elevato servos.

John, I would be very grateful to have the knowledge of how to do it. I have a t8j transmitter. The channels available are 5 & 7. The gyro is switched on 5 as per the receivers instructions.
Many thanks
Simon
