Flying a VTOL with the TX15

This tutorial uses the radio as it is on the real plane. The TX15 sends its sticks and switches on a serial line, and the plane answers on the screen of the TX15. You arm the plane with SE, and you pick QLOITER with button 2. Push the throttle stick up, and the plane climbs straight up. Press button 3 for FBWA, and the plane flies forward on its wing and levels itself. Bank it with the aileron stick, and let go. Press button 2 to hover again, and press button 6. The plane flies home and lands softly. At each step, look at the screen of the TX15.

1. Put the arm switch on: SE pressed in is on, and SE out is off (with a toggle fitted in place of the button, up is on and down is off).

   The ARMED annunciator lights up. The second lamp on the screen of the TX15 shows ARMED, and it is amber.

   

2. Press the button for QLOITER on the front of the radio: button 1 is QHOVER, 2 is QLOITER, 3 is FBWA, 4 is CRUISE, 5 is AUTO and 6 is QRTL.

   The QLOITER button lights up. QLOITER: the first lamp on the screen of the TX15 shows this flight mode.

   

3. Move the throttle stick to the high position: all the way down is low, the middle is middle, and three quarters up is high.

   The plane stays at one place in the air, and the speed in the PFD is near 0. The plane leaves your hand and climbs away. The height above home is at least 15 m.

   

4. Push the throttle stick all the way up, pull the elevator stick back a little, and press button 3 on the front of the radio. The wing motors tilt forward and the plane speeds up.

   The speed in the PFD is above 11 m/s, and the plane flies forward. The FBWA button lights up. FBWA: the first lamp on the screen of the TX15 shows this flight mode.

   

5. Move the aileron stick right: all the way left, in the middle, or all the way right.

   The horizon in the PFD is tilted, and the roll reading is more than 10° from 0.

   

6. Move the aileron stick centred: all the way left, in the middle, or all the way right.

   The horizon in the PFD is flat, and the roll reading is near 0.

   

7. Centre the elevator stick, put the throttle stick in the middle, and press button 2 on the front of the radio. The plane slows down and the wing motors tilt up.

   The plane stays at one place in the air, and the speed in the PFD is near 0. The QLOITER button lights up. QLOITER: the first lamp on the screen of the TX15 shows this flight mode.

   

8. Press button 6 on the front of the radio. The plane flies to home, and lands there.

   The QRTL button lights up. The plane lands and stops on the ground. The plane touches the ground at less than 2 m/s, and the HUD of the sim does not say CRASHED. The second lamp on the screen of the TX15 shows DISARMED, and it is dark.
