How to Upgrade the Detrum Blitz DT9 9CH RC Transmitter?


  • We have fully upgraded the Detrum Blitz DT9 RC transmitter, adding a feature to pre-store all Dynam airplanes (Gyro) data on an SD card. After the upgrade, you can quickly select the preset Gyro settings for the corresponding aircraft on the Blitz DT9 transmitter, and the system will automatically load the data, eliminating the need for manual adjustments. Once you select the Dynam planes, the Gyro stabilization data will load instantly, significantly improving flight efficiency and control precision.

    This optimized technology is designed for RC enthusiasts who prioritize efficiency and precise control. It simplifies operations, makes flights smoother, and offers a seamless flight experience. Below are the detailed steps for upgrading the DT9 transmitter.

    Detrum Blitz-DT9 Transmitter Upgrade Steps:

    1. Download the gyro stabilization data for various Dynam airplanes and the Blitz DT9 firmware upgrade program from the official Dynam RC website. Copy these files to the root directory of an SD card.

    2. Insert the SD card into the Blitz DT9 remote controller.

    3. Power on the Blitz DT9 and initiate the upgrade program.

    4. Calibrate the control sticks of the remote controller.

    5. The DT9 transmitter defaults to Mode 1, but you can switch to Mode 2 if desired.

    6. Connect the battery and bind the receiver.

    7. Import the aircraft gyro stabilization data.

    After the upgrade, the Blitz DT9 transmitter can store stabilization data for multiple Dynam airplanes, allowing for easy access and improved usability.



  • I just received the Blitz dt9, setting up the transmitter mode 2 , checking the channel monitor, all the sticks are wrong. throttle all the down indicates 50, half is 0 up is full. . push aliaron left it goes right then all the way left. same with elevator and rudder.  can't find anything in the madual that helps. ???????


  • I fixed the above by going through calibration 3 times.  However I have found the digital trim for elev. rudd. don't work. the expo just makes the center a dead spot on the stick. No way to mix flaps and elev. to prevent ballooning. Tension adjustments for the sticks don't do much. It makes the controles jumpy.

    If any one knows of a way to fix all this , please tell me.
