Both apps are compatible with RoboMaster TT aircraft.
The Tello app is for experiencing the excitement of flight and aerial photography.
The Tello EDU app is focused on programming.
One app should be completely turned off before using the other. The RoboMaster TT should also be restarted when switching between apps.
Can the Tello EDU app be used for free?
Although most of the app’s functions are free, the Tello EDU app also has games, which include some levels that require payment.
What should I do when the Tello EDU app doesn’t work?
The Tello EDU app is provided by Wistron (Shanghai) Ltd. Should you have any questions about the app, please contact Wistron by dialing +86-21-64952384 or sending an email to Thank you for your understanding.

Which programming languages ​​does the RoboMaster TT support?
The RoboMaster TT supports multiple programming languages, including Scratch, Python, MicroPython, Arduino, and plaintext SDK.


What are the dimensions and weight of the RoboMaster TT?
Aircraft Dimensions (Excluding Expansion Kit): 98 x 92.5 x 41 mm; Weight (Battery, Propellers, and Propeller Guard Included): 87g
Expansion Kit Dimensions: 49.5 x 32 x 15.2mm
(Open-Source Controller): 35.3 x 31.5 x 8.6mm
(Dot-Matrix Display & Distance-Sensing Module) Weigh (Including Open-Source Controller and Dot-Matrix Display & Distance-Sensing Module): 12.5g

[For Internal Use Only] Weight: Open-Source Controller: 9g; Dot-Matrix Display & Distance-Sensing Module: 3.5g; Extension Board: 1.3g; Extension Board with 7 pins soldered: 1.8g
How do I control the RoboMaster TT?
You can control the RoboMaster TT directly via the Tello app/Tello EDU app/Mind+, with a supported Bluetooth remote controller connected to the app, or through the SDK.
What kind of interesting things can the RoboMaster TT do during flight?
The RoboMaster TT can perform 8D Flips, fly up and down from your hand in Bounce mode, or automatically record short videos with EZ Shots.
Can the RoboMaster TT fly indoors?
Yes, The RoboMaster TT is safe to fly indoors. The RoboMaster TT can also fly outdoors, but it is only recommended to do so in windless conditions.
Is the RoboMaster TT waterproof?
What is the RoboMaster TT's flight range?
Mounted with the Open-Source Controller and connected via Wi-Fi, the RoboMaster TT's maximum flight range is approximately 100 m, but that range may vary according to your environment. When connecting the aircraft via a Bluetooth remote controller (without using the app), the maximum flight range is 15 m.
How do I replace the RoboMaster TT propellers?
You can replace the propellers by detaching the old ones and mounting new ones using the tool included in the product packaging.
How can I differentiate between clockwise (CW) and counterclockwise (CCW) propellers? Do I have to mount different propellers in specific places?
RoboMaster TT's propellers and motor casings are marked for differentiation. CW and CCW propellers must only be attached to CW and CCW motors, respectively. CCW propellers have notches near where they attach to the motors, and CCW motor casings are also marked with notches. CW propellers and motors both do not have notches. For more details, refer to the user manual.
What sensors does the RoboMaster TT have?
The RoboMaster TT has one IMU and one barometer. There is no compass or GPS inside the aircraft.
What is the maximum flight height of the RoboMaster TT?
The aircraft height limit is 30 m, and it can be set in the app with a range from 2 to 30 m.
What is the maximum payload of the RoboMaster TT?
Due to the limited carrying capacity of the RoboMaster TT aircraft propulsion system, the aircraft may stop when fully outputting power for a long time. We do not recommend loading heavy accessories onto the aircraft.
Theoretically, the RoboMaster TT aircraft (excluding the Expansion Kit) can bear a payload of about 20 grams, but the payload available in actual use is less than 20 grams. Increasing the aircraft payload will affect the aircraft's center of gravity and flight, which may cause a crash.
Does an SD card need to be mounted to the RoboMaster TT?
No. Photos and videos captured through the Tello app can be stored directly to the mobile device.
What is the maximum takeoff altitude of the RoboMaster TT?
The maximum takeoff altitude is 1,000 meters. At higher altitudes, the performance of the battery and propulsion system will decrease due to environmental factors, and the flight performance will be affected.


How do I charge the RoboMaster TT's battery?
You can either charge one battery via the Micro USB port on the aircraft or use the battery charging hub to charge three batteries in sequence.
Does the RoboMaster TT battery support hot-swapping?
No. If you do so, you may lose the photos or video taken during your last flight.
Does the RoboMaster TT need to be powered off before charging?
Yes. Connect the USB charger to charge when the aircraft is powered off, and it cannot be charged when being powered on.
What are the maintenance recommendations for the RoboMaster TT batteries?
If you do not use the battery for more than 10 days, discharge the battery level to 30%-60% and then store it, which can extend the battery life.
How does the RoboMaster TT Battery Charging Hub charge batteries?
The Battery Charging Hub will charge the battery in sequence according to battery power levels from high to low.
What is the maximum flight time of the RoboMaster TT aircraft?
The RoboMaster TT aircraft without the Expansion Kit has a maximum flight time of 13 minutes, measured at a constant speed at sea level without wind.
When the RoboMaster TT aircraft is equipped with Expansion Kits (Open-Source Controller and Dot-Matrix Display & Distance Sensing Module), the maximum flight time is 8 minutes, which is measured when flying at a constant speed at sea level without wind.
How can the RoboMaster TT battery firmware be updated?
The battery cannot be updated, and the battery will not be updated during aircraft firmware updates.
