LIPO BATTERY WARNINGS AND USAGE GUIDELINES

WARNING: Lithium Polymer (LiPo) batteries are significantly more volatile than alkaline, 

NiCd or NiMH batteries. All instructions and warnings must be followed exactly to prevent 

property damage and/or serious injury as the mishandling of LiPo batteries can result in 

fire. By handling, charging or using the included LiPo battery you assume all risks 

associated with LiPo batteries. If you do not agree with these conditions please return the 

complete product in new, unused condition to the place of purchase immediately.

• You must always charge the LiPo battery in a safe, well-ventilated area away from 

flammable materials.

• Never charge the LiPo battery unattended at any time. When charging the battery you 

must always remain in constant observation to monitor the charging process and react 

immediately to any potential problems that may occur.

• After flying/discharging the LiPo battery you must allow it to cool to ambient/room 

temperature before recharging.

• To charge the LiPo battery you must use only the included charger or a suitably 

compatible LiPo battery charger. Failure to do so may result in a fire causing property 

damage and/or serious injury.

• If at any time the LiPo battery begins to balloon or swell, discontinue charging or 

discharging immediately. Quickly and safely disconnect the battery, then place it in a safe, 

open area away from flammable materials to observe it for at least 15 minutes. Continuing 

to charge or discharge a battery that has begun to balloon or swell can result in a fire. A 

battery that has ballooned or swollen even a small amount must be removed from service 

completely.

• Do not over-discharge the LiPo battery. Discharging the battery too low can cause 

damage to the battery resulting in

reduced power, flight duration or failure of the battery entirely. LiPo cells should not be 

discharged to below 3.0V each under load.

• Store the LiPo battery at room temperature and in a dry area for best results.

• When charging, transporting or temporarily storing the LiPo battery the temperature 

range should be from approximately 40–120° F (5–49° C). Do not store the battery or 

aircraft in a hot garage, car or direct sunlight. If stored in a hot garage or car the battery 

can be damaged or even catch fire.

• Never leave batteries, chargers and power supplies unattended during use.

• Never attempt to charge low voltage, ballooned/swollen, damaged or wet batteries.

• Never allow children under 14 years of age to charge batteries.

• Never charge a battery if any of the wire leads have been damaged or shorted.

• Never attempt to disassemble the battery, charger or power supply.

• Never drop batteries, chargers or power supplies.

• Always inspect the battery, charger and power supply before charging.

• Always ensure correct polarity before connecting batteries, chargers and power supplies.

• Always disconnect the battery after charging.

• Always terminate all processes if the battery, charger or power supply malfunctions.

IMPORTANT NOTE: It’s safer and better for the longevity of the battery to store it only 

partially charged for any length of time. Storing the battery approximately 50% charged is 

typically best, however, it will take some careful management of the charge time and the 

use of a volt meter to achieve this voltage. If you have the equipment and skills to achieve 

the 50% charge level for storage it is recommended. If not, simply be sure to not store the 

battery fully charged whenever possible.

In fact, as long as the battery will be stored at approximately room temperature and for no 

more than a few weeks before the next use, it may be best to store the battery in the 

discharged state after the last flight (as long as the battery was not over-discharged on the 

last flight).

INSTALLING THE MOTOR ARMS

Fold the motor arms upwards and secure them using the straight knurled nut cover 

located on the motor arms.

NOTICE: Don’t over tighten the straight knurled nuts, It may cause deformation of the arms.

INSTALLING THE PROPELLERS

Always ensure propellers are installed properly and with thread locker on the 

fasteners. The rotors of the YUNEEC TORNADO H920 are made of high-strength 

carbon fiber, the motors are extremely powerful, meaning that if the device is misused 

there is a risk of material damage, serious injury and even fatal injury.

Mount the propellers on the motors and note the pointers ‘A’ and ‘B’ given on the 

motor arms. This distinction between ‘A’ and ‘B’ refers to the rotation direction of the 

motors. The rotation direction of the motors must match the rotation direction of the 

propellers. Mount propeller ‘A’ on motor ‘A’ and propeller ‘B’ on motor ‘B’ and use the 

screws with spring plate and 2mm Hexdriver enclosed to carefully screw in the propellers.

IMPORTANT NOTE: If the propellers are installed in the wrong places, it may cause 

crash.

FLIGHT CONTROLS

To takeoff, first start the motors in angle mode, then slowly raise the left-hand stick to 

slightly above the center position. the TORNADO H920 will takeoff and climb slowly 

(or raise the stick further until it does). Allow the stick to return to the center position 

when the TORNADO H920 reaches the desired altitude.

Take your time learning how the TORNADO H920 responds to various control inputs 

while flying. In Smart Mode the TORNADO H920 will always move in the direction the 

right-hand control stick is pushed relative to the pilot and no matter which way the 

front/nose is pointed. In Angle (Pilot) Mode the TORNADO H920 will move in the 

direction the control stick is pushed relative to the front/nose of the aircraft (and the ‘angle’ 

of movement is determined by how far you push the stick away from the center position).

RETRACTING AND LOWERING THE RETRACTABLE LANDING GEAR

The TORNADO H920’s landing gear is to keep it out of frame when a camera is 

attached. You can retract it by switching up the Landing Gear Switch on the top right 

side of the ST24. Make sure to flip the switch to the downward position when landing.

IMPORTANT NOTE: Always put down the landing gear before landing when the flight 

height is no less than 3m (10 feet) by switching down the Landing Gear Switch.

IMPORTANT NOTE: The joystick with the two control sticks respond proportionately, 

that means that the further you move the control stick from the centered resting point in the 

middle in one direction, the stronger the response and the faster the change in course.

IMPORTANT NOTE: The maximum height is restricted to 122m above the ground in 

Smart Mode and 122m (400 ft.) in Angle Mode. If at any time during flight you feel like 

the TORNADO H920 is drifting out of/beyond your control, simply release both 

control sticks. the TORNADO H920 will automatically self-level and will even hold its

position (with GPS on and a suitable GPS signal /lock) when both control sticks are 

centered. You can also activate Home Mode so the TORNADO H920 automatically 

flies itself back to the home point and lands.

13
LANDING — Position the TORNADO H920 above the area where you would like to 

land. Slowly lower the left-hand stick to below the center position. The TORNADO 

H920 will descend slowly and land. After the TORNADO H920 lands, press and hold 

the START/STOP button for approximately 2 seconds to stop the motors. Activate 

Home Mode and the TORNADO H920 will automatically fly itself back to the home 

point and will land within a 26 feet (8 meter) diameter circle around it.

WARNING: Always land as soon as possible after the first level low voltage battery 

warning, or land immediately after the second level low voltage battery warning. And 

if at any time the Aircraft Battery Voltage shown on the screen is below 21.7V, land the 

TORNADO H920 immediately.

AFTER LANDING — ALWAYS turn off the TORNADO H920 BEFORE turning off the 

ST24. Then remove the battery from the TORNADO H920 and allow it to cool to 

ambient/room temperature before recharging.

CONTROL RATE KNOB

Set the overall climb/descend and directional 

control rates. Turn the knob K2 in the clockwise 

direction for the lowest control rates (best for 

cinematic video performance). Turn the knob 

K2 in the couterclockwise direction for the 

highest control rates (best for capturing video 

of fast moving objects).

FLIGHT MODES

The ST24 is equipped with 3 different flight modes which can be selected using the 

mode switch in the top right corner above the right joystick.

SMART MODE

If the mode switch ‘10’ (S4) is fully up, then the H920 is in Smart Mode.

Although we recommend learning how to fly as soon as possible in Angle Mode, Smart 

Mode is the best choice for low-time pilots when test flying.

In Smart Mode, the H920 always flies in the direction in which the right joystick is 

moved by the pilot, regardless of the direction in which the nose is pointing. So if you 

move the stick to the right, the H920 will also move to the right regardless of the 

position of the nose, even if it is in the middle of turning. The mode can also be useful 

to pilots who have lost their bearings when flying in Angle Mode.

14
ADDITIONAL SMART MODE FEATURES:

SMART CIRCLE : In most cases the Smart Circle will keep the H920 approx. 8m / 26 ft. 

away from you provided you are positioned 8 m /26 ft. behind the H920.

NOTICE: For optimal performance, aiming the Remote controller directly at the H920. 

HOME MODE

In Home Mode the GPS system allows the Tornado H920 to automatically fly back in a 

straight line toward the direction of the last take-off position, and automatically land 

within 13-26 ft (4-8m) of the pilot. This can be very helpful for first-time pilots who are 

not quite ready to land the TORNADO H920 themselves. It can also be helpful for 

pilots that lose orientation during flight; simply activate Home Mode until the 

TORNADO H920 automatically moves toward the home position, and once you’ve 

confirmed orientation switch back to Angle (Pilot) Mode. And if the TORNADO H920 

ever loses the link with the ST24 it will automatically enter Home Mode.

When Home Mode is activated the TORNADO H920 will respond as follows:

A) When flying higher than 33 feet (10 meters) the TORNADO H920 will maintain the 

current altitude, fly back to the home point.

ANGLE MODE

If the Mode switch ‘10’ (S4) is in the centre position, then the H920 is in Angle Mode. 

Angle Mode is designed for pilots with a little experience (those who have already 

mastered Smart Mode), because in this mode the H920 moves in line with the joystick, 

in the direction in which the nose is pointed. So, if you 

move the right stick to the left, the H920 will tilt to 

the left and thus move to the left. That is assuming 

that the nose is pointing away from you. If the nose is 

pointing towards you, the H920 will move to the right 

from your point of view.

EXTRA ANGLE MODE FEATURES:

POSITION FREELY AND RETAIN ALTITUDE

The H920 will hold its position automatically when 

GPS on (if there is sufficient GPS signal) and it will 

retain the altitude level if the left stick is in the middle 

position.

WARNING: If you have not mastered the H920 in 

Angle Mode, accidents or “fly aways” may result.

IMPORTANT NOTE: Accidental damage and “fly 

aways” are not covered by the warranty.

15
B) When flying lower than 33 feet (10 meters) the TORNADO H920 will climb to 33 feet 

(10 meters) while flying back to the home point.

CAUTION: You must be certain there are no obstacles in the ‘Return to Home’ flight 

path otherwise the TORNADO H920 may come into contact with them and crash.

CAUTION: While the TORNADO H920 is in Home Mode you will have a limited amount 

of directional control. In Home Mode, only rudder can be controlled, the aileron and 

pitch can not be activated. When the copter is landing, the elevator, aileron and 

rudder can be controlled. To help avoid obstacles we strongly recommend to switch to 

Smart or Angle Mode (then you can switch back to Home Mode).

WARNING: Home Mode only works when the TORNADO H920 has a suitable GPS 

signal/lock. If the TORNADO H920 loses GPS signal/lock it will switch to Angle (Pilot) 

Mode automatically. This is why we strongly recommend learning to fly in Angle (Pilot) 

Mode as soon as possible. Otherwise, if you lose GPS signal/lock and are not able to 

properly control the TORNADO H920 in Angle (Pilot) Mode the aircraft may crash or 

even ‘fly away’.

NOTICE: The GPS function can by turned off by Switching S3 when the aircraft is 

disturbed by unknown signals. 

IMPORTANT NOTE: Crash damage and ‘fly aways’ are NOT covered under warranty.

COMPASS CALIBRATION

IMPORTANT NOTE: Calibration is not required. it is not needed unless they see 

flashing status LED.

NOTICE: In order to calibrate the compass in the YUNEEC TORNADO H920, we 

strongly recommend a team of 2 people due to the size and weight of the H920. 

Please be sure to perform the compass calibration procedure at least 11 feet away 

from the nearest cell phone or other electronic devices to ensure proper calibration.

CAUTION: Do not calibrate the compass in parking garages, close to buildings or near 

roads with a metal core. For optimum performance, only calibrate the H920 in open 

spaces, far away from electrical lines and other metal structures or concrete buildings.

Place the H920 on the flat and level surface 

and point it with its nose towards the north.

Power on the controller first and then the 

aircraft, and make sure they are connected 

correctly (If they are not connected correctly, the 

telemetry data will not display on the screen).

Turn the knob K2 in the couterclockwise direction 

to the left position near the rabbit mode.

Hold rudder stick left while at the same time toggling the mode switch more than 4 

times. If successful, ST24 will indicate compass calibration has started.

NOTICE: After switching more than 4 times, if the aircraft stays in HOME Mode, the 

indicator will blink red rapidly when compass calibration is entered successfully.

22
STEP 1) Lift the H920 airframe straight & level, then point the nose towards the north 

and hold it in this position for 4 seconds. The LED status indicators will automatically 

start to flash red/green/blue quickly. Slowly turn the H920 forward and around 360 

degrees (pitch axis) until it is flat again.

STEP 2) Turn the H920 45° to the left and then turn it forward 360° again until it is lying 

flat in your hands again.

STEP 3) Turn the H920 45° to the left and then turn it forward 360° again until it is lying flat.

STEP 4) Turn the H920 45° to the left and then turn it forward 360° again until it is lying flat.

STEP 5) Turn the H920 45° to the left and then turn it forward 360° again until it is lying flat.

CAUTION: Steps 1 to 5 should be completed within a time span of 30 seconds in order 

to achieve successful calibration.

STEP 6) Place the H920 on the ground and wait a few seconds.

If the calibration has been successful, the flight controller restarts, you will recognize 

this when you hear the acknowledgement tone, the same one you hear when you 

switch the system on.

IMPORTANT NOTE: If calibration has failed, you must switch off the aircraft manually 

by repeating the calibration process. If the calibration should continue to fail, either 

the site of calibration is unsuitable or the compass is defective. Refer to your Yuneec 

service center.

CAMERA CONTROLS (TEAM MODE)

NOTICE: The ST24 mentioned in this chapter is the one bound to the Gimbal/Camera.

GIMBAL PITCH CONTROL (GB603 AND V18/CGO4 GIMBAL CAMERA)

There is a gimbal pitch mode switch on ST24---S1. When the switch is in up position, the 

gimbal/gimbal camera is in Angle Mode. Use the K5 (C) of the ST24 to set the pitch/tilt 

position of the gimbal/gimbal camera. When the S1 is in bottom position, the 

gimbal/gimbal camera is in Velocity Mode. When the right-hand stick is in the middle 

position, it means the velocity rate is 0 for the GB603 or V18/CGO4, and it will stop 

pitching up/down. When the right-hand stick is above the middle position, the GB603 or 

V18/CGO4 will start pitching up. When the right-hand stick is below the middle position, the 

GB603 or V18/CGO4 will start pitching down. The distance between the right-hand stick and the 

middle position decides the velocity rate, the further distance, the higher velocity it would be.

CAUTION: You MUST stop recording video in order to take still photos. It will take 

approximately 5 seconds to capture a still photo and before you can take another.

CAUTION: ALWAYS stop recording video before turning off the TORNADO
