Many thanks to Andrej and RC electronics releasing a new T3000 firmware which complies with the new rules of GPS Triangle (e.g., security zones). Please click on the link and follow the instructions: T3000 Update Instructions
Please note that all pilots need to update their T3000 devices before participating in any GPS Triangle competition. Using the old T3000 firmware results in invalid flights which cannot be evaluated by the software. Therefore, please ensure that the new firmware is installed.
