Beta85X 4K 4S Whoop - it is undoubtedly the smallest 4S 4K drone. Sufficient inventory and prompt delivery.
Since YKS has shared his cinewhoop 4K with a stunning videography, people are fascinated in 4K whoop. So here we are. A real 4S 4K Beta85X whoop!!! Upgraded F4 V2 FC with BLHeli_32 16A ESC, using single N-channel MosFETs, makes the structure and performance more stable and support 4S power definetly. Mounting with Tarsier 4K camera, great choice for cruising, so you can get tons of fun in this cine whoop.
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.
High performance STM32F405 processor FC boards and tuned Betaflight OMNIBUSF4SD (OBSD). Faster input signals with lower latency and higher update rate are reachable.
Using single N-channel MosFETs on ESC board which have a lower inner resistance. It is dual MosFETs on the original BLHeli_32 ESC board.
Soldering with 25V/220uf electrolytic capacitor, for protecting ESC board, reducing the defective rate caused by the instantaneous high voltage.
Installed with Caddx Tarsier 4K camera with ND8 fliter which supports APP setting and switchable resolution setting of 4K, 2.7k, 1440P, 1080P.
Upgraded 1105 motor from 6000KV to 5000KV, with a light weight but definitely will give you extreme power and speed. Motor comes with cable connectors.
Durable and light enough frame is customized for the Beta85X. To increase its stability, we specially add an extra stiffener brace of carbon fiber. Whole drone no soldering or tinkering necessary.
450mAh 4S high rate battery is recommended by default. But pilot could also use their own batteries with battery strap. Optional and affordable.

WHAT HAVE DONE TO SUPPORT 4S?
This Beta85X has upgraded in individual parts like FC, ESC, Motor, which can support 4S power with a steady performance and bring you into a glorious FPV world.
F4 FC & BLHeli_32 ESC
Support 4S Power. 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!
Using single N-channel MosFETs on ESC board, witch have a lower inner resistance. It is dual MosFETs on the original BLHeli_32 ESC board.
Current sensor included.
ESC is mounted on the frame by screws and connected with FC boards by cables.
Last Version: The performace of the ESC is limitted and could not stand 4S power on 85X for a long time. Besides, the ESC is connected to the FC board by header pins. When pluging the battery, the ESC will loose with the FC board and cause circut shot.
Soldering with 25V/220uf electrolytic capacitor, for reducing the defective rate caused by the instantaneous high voltage.
Last Version: Not power capacitor included, which have the risk that the permanently damage on ESC by impulse voltage when plug the battery.
1105 5000KV Motor
Lower 5000KV for new Beta85X 4S, which could support 4S power which won't cause the issue of overheat or burn (maybe the ESC). Also change motor cables from 30AWG to 28AWG.
Last Version: 1105 6000KV motors with 30AWG cables. In 4S power status, the motor will be overheat and damaged. Which may cause the burnt on the ESC.
Frame Stiffener Brace
The stiffener brace of carbon fiber can reinforce the Beta85X frame, avoid unstability caused by too strong power when Beta85x is flying.
Last Version: No stiffener brace included, which would result in seriously vibration on 4S power.
CADDX TARSIER 4K CAMERA
Tarsier camera is the first DVR boards that could support 4K@30fps recording. Here is the basic manual for you to recording when get this Beta85X 4K drone.
