1st step as mentioned by David. All your servo travels are set over 50%?
In the Rx gyro menu you found the Menu (series of bars above each other)
This is where you set channels and gain control channel. Two aileron channels, two elevator channels and one or two rudder depending on model.

Orientation (tail lift and swing) tells the Gyro what axis it mounts, doing the left/right Up/Down end point learning is what sets the direction. Early gyro versions were confusing as Elevator stick up meant exactly that..stick to the top (not pulling the stick back which we all thing as up elevator) If the elevators go the wrong way try the stick the opposite way!
