After several months of research, the greatest combination of F4 V2 4S Brushless Flight Controller with BLHeli_32 16A ESC has been released which totally supports 4S power with a steady performance. BLHeli_32 16A ESC is customized for Beta85X whoop drone. Meanwhile, Beta85X is the first micro drone with a BLHeli_32 ESC at present.

BLHeli_32 is the 3rd generation ESC firmware after BLHeli and BLHeli_S, which is written for ESC's that utilize 32-bit MCU. With the increase in processing power, faster input signals with lower latency and higher update rate would be possible in BLHeli_32, such as Dshot1200!

Know more about BLHeli_32 ESC from Oscarliang's blog.

        Updated Parts

        • F4 V2 FC board has added extra 4 pluggable ports for ESC, VTX, RX and LED board, convenient installation and decreasing the dislocated PIN mounting.

        • Using single N-channel MosFETs on ESC board, which has a lower inner resistance. It is dual MosFETs on the original BLHeli_32 ESC board. Current sensor included.

        • BLHeli_32 ESC is soldering with 25V/220uf electrolytic capacitor, for reducing the defective rate caused by the instantaneous high voltage.

        Assembly Instructions

        In order to be convenient for the installation and decrease the dislocated PIN mounting, we have added a port for ESC connection. Separate installation, in case the mutural vibration may interfere between FC and ESC.

        How to attach LED board

        In order to be convenient for the installation, we have added a port for LED board connection. 

        Recommended Receiver Connection

        In order to be convenient for the installation, we have added a port for RX connection. All the ports are available on this board. So that you could connect any receiver you want on the board. For example.

        • Frsky XM/XM+ Receiver
        • Flysky Receiver
        • TBS receiver
        • DSMX receiver
