Stability System Reaction Test

This test ensures that the ﬂ ight control system is reacting properly to external

forces, such as wind. Assemble the aircraft and bind your transmitter to the

receiver before performing this test.

CAUTION: Keep all body parts, hair and loose clothing away from the

propellers at all times, as these items could become entangled.

Set the transmitter ﬂ ight mode switch to stability mode (position 1).

Holding the aircraft horizontal at the tail, arm the ﬂ ight control system by pressing

and releasing the arming button on the transmitter. The aircraft surfaces will

deﬂ ect quickly in either direction and then to center to indicate the control system

is now armed. Once the ﬂ ight control system is active, the control surfaces may

move rapidly. This is normal.

Pivot the entire aircraft as shown in the “Aircraft Movement” column of the table.

The control surfaces should react to your movements by moving in the directions

shown in the “Control Surface Reaction” column. If the control surfaces do not

respond as shown, do not ﬂ y the aircraft. Contact Horizon Product Support.

Aircraft Movement Control Surface Reaction (viewed from the rear)

Multirotor Mode (switch position 0)

Vertical mode allows the aircraft to take off and land vertically.

The ﬂ ight controls work similar to a quadcopter.

• Receiver LED green

• Limited bank and pitch angle

• Self levelling when the controls are centered

Stability Mode (switch position 1*)

Stability mode allows the novice pilot to get comfortable ﬂ ying

a ﬁ xed wing aircraft in forward ﬂ ight.

• Receiver LED red

• Limited bank and pitch angle

• Self levelling when the controls are centered

Acro Mode (switch position 2*)

Acro mode is intended for experienced pilots who are comfortable ﬂ ying the

aircraft in any orientation.

• Receiver LED green and red

• No bank angle limits

• No self levelling when the controls are centered

• Fully aerobatic capable

* The RTF version is shipped with only multirotor and stability ﬂ ight modes active.

Flight mode switch positions 1 and 2 both access stability mode, indicated by

the red LED on the ﬂ ight control board. You must unlock acro mode using the

included DXe transmitter.

Accessing Acro Mode in the RTF X-VERT

CAUTION: Acro mode is intended only for experienced pilots who have

mastered ﬁ xed wing aerobatic ﬂ ight. Attempting to use acro mode

without the necessary ﬂ ight experience may cause loss of control, property

damage or a crash. Crash damage is not covered under warranty.

To access acro mode:

1. Power on the transmitter

2. Power on the aircraft, allowing it to initialize fully.

3. Hold the transmitter sticks to the

bottom, inside corners and quickly cycle

the ﬂ ight mode switch from position 0 to

position 2 and back 3 times.

The control surfaces will cycle multiple

times. If successful, the LED on the ﬂ ight

control board will show both green and

red LEDs when the ﬂ ight mode switch is set to acro mode (position 2).

Once accessed, acro mode will be available whenever the aircraft is powered on.

It is not necessary to unlock the mode every time the aircraft is powered on.

If you wish to lock acro mode again, repeat the directions above until the receiver

LED shows stability mode (red LED) in both ﬂ ight mode switch position 1 and 2.
