I have a plane with 2 elevator servos JR ES579When I connect both via a Y lead cable with a 6.6 volts life battery I can see both keep flickering while moving them up/downBut when I connect both on a separate channels and mix the other channel with the elevator with 6.6 volts the problem disappears when I move back to the Y lead setup but with a 4.5 volts battery also no problem noticed !!any ideas could help in this problemPS: I tested several Y cables to make sure that no problem with it

I have experienced this problem numerous times in the many years I have been flying RC aircraft. It is one of the reasons why I do not use Y Harnesses. I prefer using Channel Mixing in the transmitter or I will use a JR Matchbox (or the Futaba equivalent).

In the past, I replaced the Y Harness with a higher quality one that has at least 20-22ga wire. I will NEVER use a Reversing Y Harness. My experience has been that no matter what the brand, the Reversing circuit drifts off Neutral after a couple of flights and has to constantly be readjusted. This is not easy if the Y is buried in the airframe.

A Matchbox will allow you to connect up to 4 servos to one channel and allow you to adjust Servo Direction, Endpoints, Neutral, for each servo. This is perfect for a 4 Aileron Bipe or mixing a Nosewheel or Tailwheel with Rudder, as well as Dual Ailerons, Dual Flaps, Dual Elevators, and Dual Rudders.

This servo is only rated for 4.8v. This will definitely cause twitching or perhaps worse using 6v.
