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.
