The symptoms you describe can happen if power is turned on in the boat (plugging the battery in to the ESC) with the transmitter stick at one end or the other

(you did turn on the Tx first, didn't you?)  and the crystals are a pair?

To sort out what the problem is:  unplug the ESC from the Rx - plug in a seperate battery (4.8 or 6V) to the Rx  and see if the rudder servo follows the stick.  If it doesn't the problem lies in the radio somewhere

If it does move the rudder servo lead into the channel 2 socket on the Rx - see if the rudder servo follows the motor stick/whatever.  If it doesn't the problem lies in the radio somewhere - specifically in that channel 2. 
Take out the rudder servo and battery plugs and try the ESC in channel 1. 
Connect up the drive battery to the ESC - what happens?  Does the rudder stick control the motor forwards and backwards?
If it does you have a problem (only) with channel 2  - probably in the receiver (because it is smaller, wetter and more abused)

If none of this has helped:
When you connect eveything up as usual  and connect the drive battery there are lights on the front of the front of the Viper ESC red and green which should flicker for about 4 seconds, then go off (if the transmitter throttle stick is at neutral). 
"Forward" command a the TX should turn the green light on and drive the motor forwards
reverse, similarly red

I think you may have hit the nail on the head Andrew , like you said if theres nowt wrong with the radio gear then more than likely the esc is not set up .
In neutral on my viper i get both the red and green lit , have noticed a few members of the goole club are going to change to the new esc's from Mtronics apparently they are set up free ,just switch on and go.
