The newer CX2 is supposed to be gyro compatible because it has a 3-in-1 with a separate receiver. If you have the newer setup, your rudder control gets plugged into the gyro and your gyro gets plugged into the rudder input on your receiver. The gyro's gain plug gets plugged into the receiver's gear output. Just remember to zero-out your 3-in-1's gain setting... all the way to the left.

I hope you have better luck than I did. I put the G110 on mine and I'm not impressed. My transmitter's gain has to be set to super low to offset the twitching and the G110 won't fit under the stock canopy or an aftermarket boom setup. I'm hoping a scale canopy will work...
