Adding a IGyro SRS to my older Champion SRS

  • I have an older Champion SRS (maybe 6-8 years old). I want to add Gyro and I am using 2 Rx's and multiple servos per surface. So It doesn't seem an option to plug in the servos directly due to the limited number of servo sockets in the unit, so I guess I need to set up by using my two Futaba Rxs directly to the Igyro input with patch leads, and then output with patch leads to the Rx1 and Rx2 inputs on my Champion SRS? Is that the correct setup? The patch leads will back feed current to the IGyro from the Champion SRS and I won't need a battery? I have several other IGyro3e units so I am familiar with the rest.
