3GX Signal Noise Causing servos to twitch and ESC to start. Help!!

[egiraldo911]

This question seems to have been asked many times before, but I have not been able to find a straight out answer on how to fix this. I recently upgraded the 3GX to version 5, the latest and greatest. And I noticed that there is this intermittent noise coming from the 3GX that causes the servos to twitch intermittently and the ESC also gets a signal for a split second that makes it spool up. It is just for a split moment and makes the main rotor blades move. Is there a fix to this?

Thanks.

This has been the known issue since 3.x. Remove the blades and/or disconnect the motor connection(two of the wires) when going through DIR set up. Servo twitch happens on the ground and have not seen any issue flying. Make sure you have an external BEC if you are using stock ESC. 3GX is very demanding and a good supply of power to the unit will resolve a lot of unexplained issues.

I have had the same issue. Mostly I just work through it. Blades off or disconnect two motor wires as suggested.

I just installed a new 3GX with v5 and can see and hear an occasional twitch on the swash servos every couple of minutes or so. Do you mean that .Still have not gone into the air so I can´t tell if its still there after airborne but can´t see why it shouldn´t be. External CC Bec here.

I have heard about twiches and wag that go away after reflashing with v5. Might that be the solution?
