Please check out here on our support page.–27th Septmber 2018
BETA75X Frsky recivers were all pre-flashed in FCC firmware before 27th September.
Thus,if your radio controller uses EU-LBT firmware,you have to flash the firmware of the Frsky receiver to EU-LBT firmware. Otherwise, you can’t bind successfully.

The Beta75X drone comes with “props out” in default. Why we need “props out” direction?
Default Betaflight props direction, quadcopter dips and “washes out” in hard corners. With reversed props or “props out”, no more dipping even in hardest cornering.
There are 2 choices for the Beta75X battery. For the best performance, we recommend a 2S 300mAh battery with XT30 connector. If you already have many 1S whoop style batteries and want to use them on the Beta75X drone, then we also provide a PH 2.0 option for you. The two 300mAh Lipo HV 1S batteries can be inserted into the slot with the help of an adapter, as seen below.
The AIO camera VTX on the Beta75X is a customed version of Z02. The VTX board and camera board are split and 35 degree camera mount for more fast flying. At the same time, it have all the other function of the Z02 camera, like output power switchable between 0mW, 25mW and 200mW. Smart audio is available for VTX remote control in default.
How to change the frequncy or output power via remont control, please check the manual Smart Audio.

1. About the LED at the rear for Beta75X
For the moment, the FC board doesn’t support programable LED like WS2812 etc. The LED holder is designed on the frame nowadays. So we will update the FC board on the next version and release the suitable LED board.
Note: there is NO rear LED holder for Beta65X in default.
2. I am interested in connecting an HD camera and DVR, but I don’t want to overload the circuit of 5V.
The 5V regulator on the FC board could handle 2A of load. So you could use it for HD camera or DVR board. More details, please check the FC board page.
3. Does this drone have current sensor?
This drone does NOT have a real current sensor. We use the virtual current meter in Betaflight. When properly calibrated, it can be accurate enough to be useful. Here is the pre-calibrated value out of the box.
set current_meter = VIRTUAL
set ibatv_scale = 90
set ibatv_offset = 29
