Like Mort said it is very simple to set up. You don't need to overthink it. You just need to make sure that the lead plugged into the rx is the same channel as the gyro ie: A plug into the rudder on the RX the rudder needs to be in A socket on the Gyro. It doesn't matter what order you use to plug them in because it learns the channels in the set up.
Yes that is why you need to move the sticks pretty quick during setup. If you mess up you don't sweat it. You can power down and then back up and do it over and over. It took me about 3 times to get it right. You check after it is done by moving the model and watching the control surfaces. They should move the opposite direction you first move the model. You may want to turn up the gain to really see the movement.
