I have an NX8 transmitter and a twin engine Boat (Riva) I wish to set up the electrics so I can steer with the rudders and the engines. I have done this before but on a different TX. What happens is when you give right rudder the left engine slow and the rightengine speeds up as well as the rudders turning to right. It is useful for steering tight spaces. will have it on one stick so centred it will not move forward will mean forward and right will mean right, pull back and reverse left stick give left turn. Can anyone help me please. Brian
