Recommend Battery

It is highly recommended to use a 300mAh 3S 45C battery for this 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 x 300mAh = 13.5A.


We DO NOT recommend the 1103 11000KV motors for 3S power because the motor may overheat or burn which will cause permanent 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, 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 the 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.

Know more about current sensor and calibration.

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

Please don't forget to plug the battery when you try to connect the connector to the 2-4S brushless FC. Find out more details on our support page.
