Finally worked it out
The elevator horn had been put on the elevator upside down which when placed onto the plane was then able to be hooked to the clevis that actually should have been the rudder clevis but was back the front in the receiver and vise versa for the rudder.
Thus the elevator servo appeared to be reversed but in actual fact was the wrong servo
BUGGER
But it's all good now and back in the box and wrapped
Thanks for all the advise
Cheers
