Activating the throttle cut switch while the motors are armed will immediately disarm the motors. You must return the throttle cut switch to the “arm” (0) position and

then use the motor arm/disarm switch to re-arm the motors.

BNF Transmitter Setup

The X-VERT™ aircraft requires a transmitter with a minimum of 6 channels with one 3-position switch and one momentary switch available.

Flight Modes are controlled by channel 5 (GEAR). Motor arming/disarming is controlled by channel 6 (AUX 1).

IMPORTANT: After you set up your model, always rebind the transmitter and receiver to set the desired failsafe positions.

Using the settings shown in the table:

Sw itch B = Flight Modes

Position 0 = Multirotor Mode Position 1 = Stability Mode Position 2 = Acro Mode

Switch I = Motor Arm/Disarm Switch H = Throttle Cut

Expo

If desired, you may add exponential to soften the feel of the controls around neutral. We recommend starting with 10% on the aileron and elevator channels for Acro Mode only. You may adjust the expo values to better suit your ﬂ ying style.

Battery Installation and ESC Arming

Battery Selection

The RTF version includes a 2S 7.4V 800mAh LiPo battery (EFLB8002SJ30). We recommend a 2S 7.4V 450-800mAh LiPo battery. Refer to the Optional Parts list for other recommended batteries.

Binding Procedure

1. Center all trims and move the throttle stick to the lowest position.

2. Power OFF the transmitter.

3. Place the aircraft upright on the wingtip landing gear, on a level surface. Install a fully charged ﬂ ight battery and connect it to the ﬂ ight controller. The ﬂ ight controller will beep once and the green LED will ﬂ ash to indicate the ﬂ ight controller is initializing.

4. When the red LED on the ﬂ ight controller continuously ﬂ ashes, power ON the transmitter in bind mode. Refer to your transmitter’s manual for speciﬁ c binding instructions. To enter bind mode in the RTF included DXe transmitter, press and hold the bind button and then power on the transmitter. The LED indicator will ﬂ ash rapidly to indicate the transmitter is in bind mode. Release the bind button.

5. The receiver is bound to the transmitter when the LED on the receiver glows solid.

IMPORTANT: After binding the receiver and transmitter for the ﬁ rst time, the transmitter must be powered on before the aircraft. Failure to power on the transmitter ﬁ rst will cause the receiver to automatically go into bind mode, requiring the transmitter and receiver to have to be re-bound.

Installation

1. Lower the throttle and throttle trim to the lowest settings. Power on the transmitter and wait approximately 5 seconds.

2. Open the battery hatch.

3. Apply the loop side (soft side) of the hook and loop tape to the bottom of your battery and the hook side to the battery tray. Use enough hook and loop material to ensure the battery is held securely in place through even the most violent aerobatic maneuvers.

NOTICE: Failure to use adequate hook and loop material may allow the battery to become dislodged or ejected in ﬂ ight. Movement of the battery in ﬂ ight may cause a change of the center of gravity and loss of control.

4. Install the fully charged battery centered in the battery compartment.

5. Connect the battery lead to the aircraft power lead, noting correct polarity.

CAUTION: Connecting the battery to the aircraft power lead with reversed polarity will cause damage to the ﬂ ight controller and the battery. Damage

caused by incorrectly connecting the battery is not covered under warranty.

6. The aircraft must be either vertical on the landing gear or horizontal on its back to initialize. Keep the aircraft immobile and away from wind or the ﬂ ight control system may not initialize.

CAUTION: Always keep hands away from the propeller. When armed, the motor will turn the propeller in response to any throttle movement.

7. Close the battery hatch.

8. Refer to the Center of Gravity section to ensure the model balances at the recommended CG.

Center of Gravity (CG)

The CG location is within 126-136mm (measured forward from the trailing edge of the wing).

CAUTION: Failure to conﬁ rm the correct center of gravity may cause a loss of control and a crash. Crash damage is not covered under warranty.

Control Centering

Before the ﬁ rst ﬂ ights, or in the event of an accident, make sure control surfaces are centered when the transmitter controls and trims are neutral. The transmitter sub-trim must be set to zero. Adjust the linkages mechanically if the

control surfaces are not centered. Make the U-shape narrower to make the connector shorter. Make the U-shape wider to make the linkage longer.

Flight Control Direction Tests

Transmitter Input Test

This test ensures that the ﬂ ight control system is reacting properly to your transmitter inputs. 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.

Move the transmitter controls as shown in the “Transmitter Input” column of the table. The control surfaces should react to your inputs by moving in the directions shown in the “Control Surface Reaction” column. If any of the control surfaces do not respond in the proper direction, ensure the corresponding transmitter channel is NOT reversed.

• 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.

Understanding the Primary Flight Controls

The X-VERT aircraft is capable of both vertical, multirotor-style ﬂ ight and forward, airplane-style ﬂ ight. It is important to understand how the primary ﬂ ight controls function and how the aircraft reacts in both ﬂ ight modes. Take a few minutes to familiarize yourself with the controls prior to attempting your ﬁ rst ﬂ ight.

Flying Your Aircraft

Consult local laws and ordinances before choosing a ﬂ ying location.

NOTICE: While the aircraft is capable of forward ﬂ ight in light to moderate winds, we

recommend using multirotor mode only in very light wind or calm conditions. Using multirotor mode or transitioning from forward ﬂ ight to multirotor mode in windy conditions will cause the aircraft to be blown downwind and could cause a loss of control or a crash. Use only the forward ﬂ ight modes for ﬂ ying in windy conditions.

Range Check your Radio System

Before you ﬂ y, range check the radio system. Refer to your speciﬁ c transmitter instruction manual for range test information.

Just Before Flight

The recommended battery is the EFLB8002SJ30 800mAh LiPo. For best results, always use a fresh battery. Due to the increased battery draw of this or any vertical lift aircraft, using an old or worn battery will give far shorter ﬂ ight times.

For your ﬁ rst ﬂ ights with the recommended 800mAh battery pack, set your transmitter timer or a stopwatch to 8 minutes.

NOTICE: Never ﬂ y the aircraft without ﬁ rst setting and activating a timer.

After 8 minutes, land the aircraft. Adjust your timer for longer or shorter ﬂ ights depending on your preference and battery usage.

Arming

The X-VERT can be armed in any of the three ﬂ ight modes. The active ﬂ ight mode during arming determines how the aircraft will indicate it is armed and ready for ﬂ ight.

Prior to arming, lower the throttle to the lowest setting. The aircraft will not arm unless the throttle is fully lowered.

When the aircraft is armed in multirotor mode, the motors will spin up to idle speed. When the aircraft is armed in either stability or acro mode, the elevons will cycle

and then return to center. The motors will not run until throttle is applied. IMPORTANT: As a safety feature, arming in one ﬂ ight mode and changing to

another ﬂ ight mode prior to adding throttle will cause the aircraft to disarm.

Vertical Takeoff

1. Place the aircraft vertically on the landing gear on a ﬂ at, level surface with the top facing you. The aircraft must be sitting vertically to arm in multirotor mode.

2. Set the ﬂ ight mode to multirotor ﬂ ight.

3. Lower the throttle to the lowest setting. The aircraft will not arm unless the throttle is fully lowered.

4. Arm the aircraft by pressing and holding the motor arm/disarm switch. When the aircraft is armed in multirotor mode the motors will spin up to idle speed.

5. Gradually increase the throttle until the model lifts off and is approximately 2 ft. (600mm) off the ground. Avoid forcing the aircraft into the air.

Hovering and Vertical Flight

Making small corrections on the transmitter, try to hold the aircraft in one spot. If ﬂ ying in calm winds, the model should require almost no corrective inputs. After moving the aileron/elevator stick and returning it to center the model should level itself. The model may continue to move due to inertia. Move the stick in the opposite direction to stop the movement.

After you become comfortable hovering, you can progress into ﬂ ying the model to different locations, keeping the top pointed towards you at all times to aid with orientation. You can also ascend and descend using the throttle stick.

When comfortable with these maneuvers, attempt ﬂ ying with the aircraft in different orientations. It is important to keep in mind that the ﬂ ight control inputs will rotate with the aircraft, so always try to picture the control inputs relative to the nose of the aircraft. For example, pushing the elevator stick forward will always pitch the nose toward the bottom of the fuselage, causing the aircraft to move forward and vice versa.

Hovering and multirotor ﬂ ight is best attempted in low wind conditions. Attempting to ﬂ y in higher winds will cause the aircraft to drift downwind dramatically if the top or bottom are turned into the wind. It is possible to hold position somewhat if the aircraft is turned sideways into the wind, but this is recommended only for more experienced pilots.

Lowering the throttle to descend while ﬂ ying in multirotor mode in choppy or windy conditions may cause the aircraft to appear “bouncy” or erratic. This is normal as the ﬂ ight controller reacts to compensate for the moving air.

Transitioning In Flight

To transition to stability, forward ﬂ ight from multirotor ﬂ ight, change the

ﬂ ight mode switch on your transmitter to the stability ﬂ ight mode position. The throttle will increase slightly and the aircraft will pitch forward until forward ﬂ ight attitude has been achieved. It is normal to have some slight oscillations in pitch as the aircraft transitions into forward ﬂ ight. While in stability ﬂ ight mode the motors use differential thrust to provide yaw control.

NOTICE: Always ﬂ y in a clear and open area. While the transition from multirotor to forward ﬂ ight does not require much space, you will not be able to change the direction of ﬂ ight until the transition is complete. NEVER attempt to transition to forward ﬂ ight indoors in anything but a large open space such as a large gymnasium.

To transition to multirotor ﬂ ight from forward ﬂ ight, reduce the airspeed and change the ﬂ ight mode switch on your transmitter to the multirotor ﬂ ight position. The throttle will increase slightly and the aircraft will pitch up until it reaches a multirotor attitude.

NOTICE: If you are ﬂ ying in wind, the aircraft will be blown downwind after it transitions to vertical mode.

Transition to vertical ﬂ ight at low throttle will cause the aircraft to descend until more throttle is applied.

Stability and Acro Forward Flight

Fly the aircraft and trim it for level ﬂ ight per the In Flight Trimming section. The X-VERT ﬂ ies in a very similar manner in forward ﬂ ight to any other ﬁ xed-

wing aircraft. It is capable of a wide range of aerobatic maneuvers, including loops and rolls. Additionally, the differential thrust of the motors allows for unique spinning and tumbling maneuvers.

Hand Launching

Hand launching is preferred when ﬂ ying in higher winds or when vertical takeoff may not be possible.

1. Lower the throttle to the lowest setting. The aircraft will not arm unless the throttle is fully lowered.

2. Power on the model normally, allowing it to initialize completely.

3. Set the ﬂ ight mode switch to stability mode.

4. Hold the aircraft horizontal, with a ﬁ rm grip at the rear-center of the airframe, being careful not to interfere with the control surfaces.

5. Arm the aircraft by pressing and holding the motor arm/disarm switch. When the aircraft is armed in either stability or acro mode, the control surfaces will cycle left and right and then return to center. The aircraft is now armed in stability mode. The motors are armed and will run with any throttle input.

6. Increase the throttle to approximately 50–75%.

7. Give the aircraft a light, underhand toss into the wind.

Landing

The preferred method of landing is to transition the aircraft into multirotor ﬂ ight mode and bring it into a low hover. Slowly lower the throttle to descend to a soft landing. Immediately activate throttle cut or press and hold the motor arm/ disarm switch to stop the motors when the aircraft touches down. Failure to stop the motors may cause the aircraft to skip or hop across the ground if the ﬂ ight controller does not recognize the aircraft has landed.

It is possible to land the aircraft in forward ﬂ ight as well when conditions dictate it, such as in high wind. To land while in a forward ﬂ ight mode, turn the aircraft into the wind and lower the throttle to decrease the forward speed. Fly the aircraft to approximately 6 inches (15cm) or less above the runway, using a small amount of throttle for the entire descent. Keep the throttle on until the aircraft is ready to touch down.

Just before touch down, keep the wings level and the airplane pointed into the wind. Gently lower the throttle while easing back on the elevator to bring the aircraft to touch down on the runway as slowly and gently as possible. Using stability mode for landings will help stabilize the aircraft.

IMPORTANT: The aircraft will automatically disarm after sitting for approximately 3 seconds with no throttle, no control inputs or aircraft movement.

The average ﬂ ight time with a mixture of multirotor and forward ﬂ ight using the recommended 800mAh ﬂ ight battery is approximately 8 minutes.
