Why are my servos binding/making a noise?

[rhysduk]

Sorry for what is probably a very stupid question...

Recently turned over to 2.4 (Futaba 8FG) and 'trying' to get my sloped setup.
Tx and rx are binded.
Now the servos are making an unnerving noise. It sounds like they're binding when at neutral. Any ideas?

Rx is an OrangeRx FASST.
Tx is set to 7ch mode (not MULTI - it won't bind with rx in MULTI mode.)

Appreciate any help.

What servos are they mate?

I believe they are Futaba s3003 (analog).
That's what I put in when I built it up originally with my 35mhz Tx.

Edit: THEY ARE S3003's. and 1x S3001 for Elevator

Ok, so it seems the Rx was set to HighSpeed mode for Digital Servo's.
But, now im getting twitching on my CH1 aileron... Why is nothing straight forward
Here's a link for the vid:

Ok some progress...
The right aileron will only twitch when the elevator servo is plugged into the Rx on Ch2.
I have this setup:
Ch1 -Right Aileron
Ch2 -Elevator
Ch6 -Left Aileron
