Power Cable

There are 2 choices for the Beta75X battery. For the best performance, we recommend a 2S 350mAh 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 customized version of Z02. The VTX board and camera board are split and 35 degree camera mount for more fast flying.

FAQ

1. Update about the LED at the rear for Beta75X

The FC board is now upgraded to V1.2. It can support programable LED like WS2812 etc. The LED holder is designed on the 75X frame nowadays. 

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

4. How to connect the receiver to the 2S brushless FC?

Please don't forget to plug the battery when you try to connect the connector to the 2S brushless FC. Find out more details in our support page.

5. Cli Dump for different versions of the 2S Whoop are provided in our support page.

6.  For some reason whenever i turn off and turn back on the quad vtx resets to 25mw even if i save the setting.

The button and SmartAudio cannot be used at the same time. You can either change the vtx setting by button or SmartAudio.

If you only use the button, you can find SmartAudio on the Ports page and set it to Disabled.
If you only use the SmartAudio, you can find more details here to know how to do this.
