Hye.
I'm pretty sure it's a brownout, if the 3GX lights were flashing it's trying to tell you something. I have read that if the govenor isn't diabled when it's not being used that it can cause problems, but it will not go to full power on it's own.
As Red3 has said, my next question to you was going to be are you using an Align regulator and you are. Unfortunately while this is a good unit and works well, the conversion to FBL puts the servo's under more strain and as a result they will pull more current in flight. The Align unit is only rated to 6amps and each servo can pull 2+ amps, so the 3 eCCPM servo's alone can overpower the BEC, add on a fourth tail servo and 3 gyro's all working the servo's and you could be in trouble.
You can test this on the bench, power on and then cycle all channels really quickly and if it's anythign liek the recent stories on HF forum the sats will start blinking and so to will the 3GX as the power dips and your radio link fails.
The full revs is a failsafe problem, again it's easily checked and eliminated by turning on the model, and turning off the transmitter to simulate a loss in radio signal. If the throttle servo goes to full power then that is the answer.
As to a suitable regulator, ideally it needs to be rated to 8 amps or more for most FBL of this size and above. The ElyQ is quite a good one as it takes the current draw away from the 3GX (or any FBL unit) as the servos connect to it and get their power from a high amp output circuit. There are other makes which work in similar ways and take power demands away from the 3GX itself.
