LIPO BATTERY WARNINGS AND USAGE GUIDELINES

WARNING: Lithium Polymer (LiPo) batteries are signicantly 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 

re. 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 

ammable 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 ying/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 re 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 ammable 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 re. 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, ight 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 re.

• 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 ight (as long as the battery was not over-discharged on the 

last ight).

ASSEMBLING THE H920

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 ber, 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 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.

INSTALLING THE FLIGHT BATTERIES

After the ight batteries has been fully charged, they are ready to be installed in the 

TORNADO H920:

STEP 1) Open the battery compartment ap with the status LED mounted on it by 

carefully pulling the top edge of the ap.

STEP 2) Slide the batteries into the compartment with the EC3 blue, polarityprotected connector leads / wires downward.

WARNING: The aircraft can take-off with 2 or 3 batteries. If utilizing 2 ight batteries, 

make sure the 2 batteries are placed evenly within the two sides to balance the 

aircraft. The voltage between each battery pack must be within 0.1V prior to 

connecting the batteries to the aircraft. Be sure to use the included battery voltage meter.

STEP 3) Connect the ight battery to the relevant socket above the respective battery 

on the H920 using the EC3 blue, polarity-protected connector.

NOTICE: The white socket is for battery charging, do not connect it to any port when 

installing the batteries. If you do not install the battery in the correct orientation it will 

not be possible to make a positive connection.

FLIGHT CONTROLS

To takeoff, 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 ying. 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 ip the switch to the downward position when landing.

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

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 ight 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 a suitable GPS signal /lock) when both control sticks are centered. You 

can also activate Home Mode so the TORNADO H920 automatically ies 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 two (2) seconds to stop the motors. 

Activate Home Mode and the TORNADO H920 will automatically y 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 rst 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 SLIDER

Set the overall climb/descend and directional 

control rates. Use the bottom most position 

closest to you for the lowest control rates (best 

for cinematic video performance). Use the top 

most position furthest away from you for the 

highest control rates (best for capturing video 

of fast moving objects).

FLIGHT MODES

The ST24 is equipped with 3 different ight 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 y as soon as possible in Angle Mode, Smart 

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

In Smart Mode, the H920 always ies 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 ying 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.

HOME MODE

In Home Mode the GPS system allows the Tornado H920 to automatically y 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 rst-time pilots who are 

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

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

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

conrmed 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 ying higher than 33 feet (10 meters) the TORNADO H920 will maintain the 

current altitude, y back to the home point, or active home point if the ST24 has 

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 (if there 

is sufcient 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 “y aways” may result.

IMPORTANT NOTE: Accidental damage and “y 

aways” are not covered by the warranty.

15
enough satellites for Follow Me, then descend vertically until it lands.

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

(10 meters) while ying back to the home point, or active home position, then will 

descend vertically until it lands.

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

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. 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 y 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 ‘y away’.

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

COMPASS CALIBRATION

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

ashing 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 at and level surface and 

point it with its nose towards the north.

Power on the controller rst 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).

Move the Proportional Speed Control Rate 

Slider - located on the right side of the 

controller - to the highest 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.

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 ash red/green/blue quickly. Slowly turn the H920 forward and around 360 

degrees (pitch axis) until it is at again.

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

at in your hands again.

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

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

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

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 LED status indicator lights up green 

continuously and the ight 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, the LED status indicator lights up red 

continuously and you must be repeat the calibration process. If the calibration should 

continue to fail, either the site of calibration is unsuitable or the compass is defective.
