Precedent Huntsman 461/2 Inch
HI Glyn
Most of the bits you mention are plug and play, I take it the motor is mounted, fit leads to the motor, long enough toreach the motor with about 2" extra, next decide were your ESC will fit, keep the power leads and the radio leads separate, then decide were to fit the reciever and plug in the ESC to the drive battery and test that all is working, an on/off switch in the power lead to the battery is a good idea.
The arkward part is fitting the servo for the rudder, it can be fitted close to the the rudder with a short pushrod, needing an extention to the servo lead, or fitted closer to the receiver and a longer pushrod.
Once you have decided which way to go it is just a fitting excercise. Sound easy, decide were the components will go then fit the wireing and pushrod.
Hope this is a help, if your still unsure give me a shout and will help out
