	We have got through about 3/4 of the turn and it is the time to think about returning to straight and level flight in the desired direction. Return the controls to the middle position (you may need to correct the turn with a little right ailerons and/or rudder). If necessary give slight elevator input to settle your model into a straight and level flight.

	ALPHA 1500 V2 is not a large model, so do not let her fly too far away. Please remember you can control your model only so long as you are able to see the model’s orientation in the air. The safe range of your radio is much further than the range of your eyes!		'''How to control your model?'''

	How to control your model?

	In contrast to cars or boats, aircraft fly in three dimensional space which makes full control more complex. Turning the steering wheel left or right makes a boat or car to turn left or right, applying more throttle the vehicle speeds up – and this is it. Moving the control sticks left or right has more effect than simply turning the model. The aileron and rudder control will be explained later.

Moving the control sticks left or right has more effect than simply turning the model. The aileron and rudder control will be explained later.

	'''Please note:''' the control is fully proportional – the more you move the stick, the more movement of the control surface. The actual stick movement required is mostly quite small, and almost never from one end stop to the other!		{{Note\|type=info\|'''Please note:''' the control is fully proportional – the more you move the stick, the more movement of the control surface.

	'''Elevator''' controls the model in the vertical axis; apply up elevator and your model’s nose will raise (and the model will climb if it has sufficient power), apply down elevator and your model will descend. Please note that your model can only climb if it has sufficient power applied. Your model will not necessarily climb simply because you have applied up elevator, and will normally need full power applied for a safe gentle climb. If the climb angle is too great, or the power applied insufficient, your model will lose flying speed until the minimum (stall) speed. At the stalling speed (when the airflow starts to break away from the upper surface of the wing), your model will start to feel as though it is not responding as normal to control inputs, and then drop with little warning – apply down elevator to regain flying speed and full normal control.

			===== IV. Exit program mode =====
			Move the throttle stick to the bottom position within 3 seconds after you hear two long beeps and one short beep (emitting from the motor) can get you exit the programming mode. The motor beeps “Number” beeps to indicate the number of LiPo cells you have plugged in, and then a long beep to indicate the power system is ready to go.

Moving the CG forward the model flight will be more stable, moving backward the controls will be become more sensitive, also the thermaling performance might improve slightly. Note: Moving back the CG too much could cause your model would be hard to control or even so unstable that you would not able to control it at all.

In addition, the protection voltage value of the low-voltage protection function corresponding to the low/medium/three modes is about 2.8V/ section, 3.0V/ section and 3.4V/ section. This value is the voltage of a single battery, multiplied by the number of lithium batteries automatically identified by the electronic governor or the number of lithium batteries manually set, which is the protection voltage value of the battery.
