Good evening Brian, I have a few models using the same radio and electrics as you and don't usually have any problems.
But when you set up and test your system if your throttle channel is ok then the esc is providing the correct voltage to the reciever.
Any problems with the rudder servo could be you didn't have it centered when you fitted the control arm.
Disconect the servo arm and test again, hopefully this will show up any problems.
Remember always turn on the transmitter and centre the sticks, before the model the servo will usually kick and settle on centre when you switch the models power on.
Try this and let us know how you get on.
Cheers Colin.
