Here we see a great progress with the new Beta75X 3S Whoop HD version which is pre-installed with a Turtle V2 camera and can support 3S battery! 

It enables you to experience powerful flight and enjoy the high quality video at the same time. For those people who want to record a video by flying in a park or at home, Beta75X 3S HD whoop is definitely a best choice. 
A lighter build safer around people, quieter, and easier to control.


Beta75X starts a new era of 3S whoop drones. With a big improvement in power, you could fly real acro, like a larger quad, but is still small enough, safe enough, and quiet enough to fly anywhere.

With the high performance STM32F411CEU6 processor FC boards and tuned Betaflight MATEKF411 (MK41) firmware, everyone could fly the Beta75X drone like a racing pro.

Experience high quality video and high-definition DVRs with the Caddx Turtle V2 on Beta75X HD version.

Durable and light enough frame is customized for the Beta75X. A total weight of 57.4g give pilots a good balance of weight and nice punch on 3S battery.

Whole drone no soldering or tinkering necessary. Customized 1103 8000KV motors with cable connectors, provide powerful thrust on 3S, just plug and play.

300mAh 3S high rate battery is recommended by default.

Highly recommend the newest 333mAh 3S battery for this small beast.

We DO NOT recommend the 1103 11000KV (or above) motors for 3S power because the motor may overheat or burn which will cause permanently damage on the motor or ESC. 
Also DO NOT use 1103 8000KV motors for 2S power, the performance will be not as good as the 1103 11000KV motors due to lack of power.

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.

1. Does this drone have current sensor?

Yes, it has a real current sensor. So no need to use the virtual current meter and you could get a more accurate current value. In order to use this current sensor hardware, some configurations in Betaflight GUI are needed.
