Bullet Point

  • 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 BETAFPVF411(BEFH) firmware, everyone could fly the Beta75X drone like a racing pro.
  • Enjoy the real-time FPV feds and fast, powerful flight at the same time with the customized EOSV2 camera.
  • Durable and light enough frame is customized for the Beta75X. A total weight of 45.3g 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 but not including.


    Recommend Battery

    Highly recommend the newest 300mAh 45C batteries for this small beast. The maximum current requirement for this drone is about 11A, so do NOT use 3S 300mAh battery under 35C.

    How to calculate the highest current the battery could provide? For example, 45C 300mAh 3S battery, the maximum discharge current is about 13.5A.

    45C * 300mAh = 13.5A.

      We DO NOT recommend the 1103 11000KV motors for 3S power because the motor may overheat or burn which will cause permanently damage on the motor or ESC. And don't use 1103 8000KV motors for 2S power, the performance will not be as good as the 1103 11000KV motors since lack of power. 
      Motors Recommend Battery Voltage
      1103 11000KV 2S 350mAh Battery 7.4V 
      1103 8000KV 3S 300mah Battery 11.1V

      Note: Please kindly cut out these three sticks ① ② ③ by using the scissors as the following picture to fit the 3S 300mah Battery(R-Version ), be careful not to cut the wire of the receiver.

          Prop Out & Wash Out

          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.Know more about "Props Out".

          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.
