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.
| 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".
So here we go, in this video we tested Beta75X HD 3S with dive, powerloop and spilt-S. NO WASHOUT at all!!
