The Beta75X frame is designed for 75mm brushless whoop builds, natively supporting BetaFPV 1103 motors, and featuring a customized LiPo slot. The battery slot supports 2S batteries out of the box, and can easily be modified to support larger 3S 300mah batteries. The FC mounts are still whoop standard. This frame is a great balance of weight and durability. It ships in a strong plastic packageto protect from deformation during shipping.

Battery Slot

In default, the battery slot is designed for 2S 300mAh battery. If you already have many 1S whoop batteries and want to use the them on the this frame, what shall we do?

As show below, with the help of a foam adapter, 2pcs 300mAh Lipo HV 1S whoop style batteries are inserted in the slot suitably. Don't forget to get a double PH-JST 2.0 connectors power cable.

But we highly recommend 3S batteries for this small beast.

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 be not 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 carefully not to cut the wire of the receiver.
