However, before taking off, it is better to verify a couple of elements. Please note that there are two models of remote controllers (RC) being used with the CoaX, depending on when the order was made. Please see the page [[:Category:Coax_-_hardware\|Hardware]] to know which RC you have.

		+	===If you use the [[media:RC_cmd_2402.png\|WK2402]] remote control===
		+	* Check the battery level (below 11V or above 12.6V you should change the battery pack)
		+	* Check if the throttle on the RC is at its lowest position
		+	* Turn-on the RC transmitter
		+	* Check if the trim switches (Roll and Pitch only) of the RC are at their middle point (50%)
		+	* Put the manual/auto switch to '''MANUAL''' (say below 50%)
		+	* Place the helicopter on a horizontal surface, in a big-enough room (depends on your piloting skills...)
		+	* Power-up the CoaX helicopter - It is important to keep the coax static while the IMU is initializing (Green LED off)
		+	* At power-up, the CoaX is by default in '''Kill''' position (RED LED on). Go out from the Kill mode by moving the height (throttle) stick to the lower RIGHT corner, then release it. The RED LED goes off. This enables the motors, but does not start them
		+
		+
		+	In order to take-off, and for security reasons, the CoaX must be first switched to IDLE mode and then to TAKEOFF mode (See the Navigation modes in [[:Category:Coax_-_software\|Software]] page). This is very easy:
		+
		+
		+	* Make '''2xBip (clicks) UP''' with the '''Stop/Idle/Takeoff switch'''. Since the helicopter was just powered-up, this will switch the mode from STOP to IDLE. There is a timeout of 10sec in IDLE mode, after this time, the CoaX will switch back to STOP mode unless intentionally switched to TAKEOFF mode.
		+
		+	* Within these 10sec, repeat the previous '''2xBip (clicks) UP''' with the '''Stop/Idle/Takeoff switch''' and the helicopter will switch from IDLE to TAKEOFF mode. The rotors will spin faster, but since the throttle stick is at the minimum, the height setpoint is thus very low (<10cm)
		+
		+	* Move '''slowly''' the throttle stick to a slightly higher position and the CoaX will take-off. Since the height of the CoaX is controlled, it will remain constant, unless you move again the throttle stick
		+
		+	* You can use the other sticks to orient or move the helicopter. Please see the picture of the [[media:RC_cmd_2402.png\|WK2402]] for details
		+	* To land in MANUAL mode, you need only to put down the throttle stick '''slowly''' to its lowest position
		+	* To stop the motors, it is better to switch back to IDLE mode by performing, this time, a '''2xBip (clicks) DOWN''' with the '''Stop/Idle/Takeoff switch'''. Again '''2xBip (clicks) DOWN''' with the same stick, the motors will stop completely.
		+
		+
		+	Obviously, one can stop the motors '''immediately''', from '''any mode''' by moving the height (throttle) stick to its lowest, left position.
		+
		+	It is advised to trim the roll and pitch axes during the first flight, using the corresponding trim sliders. If the CoaX is well trimmed, it should look like pinned in the air!

	CoaX® is delivered with a 4channels, 2.4Ghz remote control (RC) unit. At power up, the CoaX receiver reduces its sensitivity to check only for RC emitters that are close to it (<1m distance). The CoaX receiver selects then the strongest signal to pair with it. Once the pairing is done, it remains until the helicopter or the RC is turned off. In flight, the range can be several tens of meters even indoors. However, this depends on the obstacles between the RC and the helicopter.

		+
		+	* '''Height setpoint stick''' - Sets the desired height of the helicopter from the ground. The lowest position makes the CoaX to land. The uppermost point represents the maximum authorized height (set by software) to be reached by the CoaX.
		+
		+	* '''Yaw-rate setpoint stick''' - Sets the desired yaw-rate (rotational speed around the vertical axis) of the helicopter. This stick goes back to its neutral point (null speed) as soon as it is released.
		+
		+	* '''Swashplate Roll (or Pitch) angle stick''' - Controls directly the angle of the servo-motor responsible for the rolling (or pitching) of the CoaX. This stick goes back to its neutral point (null angle) as soon as it is released.
		+
		+	* '''Roll (or pitch) trim slider''' - Sets the trim points of the Roll (or Pitch) angles of the swashplate (just like on traditional RC).
		+
		+	* '''Display''' - Displays miscellaneous info like battery level, channels' state or battery level, etc.
