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.

FEATURES

  • 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 WE 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.

Power Capacitor

Soldering with 25V/220uf electrolytic capacitor, for reducing the defective rate caused by the instantaneous high voltage.

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.

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.

 

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.

2s-top-52fa08e0-9865-4bdb-b200-0a268548f8d0-grande.jpg

 

There are 2 buttons on the DVR board. One is for wifi and recording. The other one for power and recording video mode.

There are 2 LEDs to indicate the recording status.

For more details about the CADDX Tarsier camera, please download the Tarsier Manual

 

Also, there is a CADDX Tarsier APP on Apple Store (for IOS phone) or Google Store (for Android phones). Through the APP, you could change the settings like Metering, White balance, EV compensation, IOS limit, Sharpness, Contrast, Saturation.

VIDEO QUALITY AND SHOOTING TIPS

We care about mostly is the video quality of this 4K drones. Here is some you must know about and some advice for a perfect video.

 

4K@30fps VS 2.7K@60fps

The frames per second of the Caddx Tarsier camera is 30fps on 4K mode. It is suitable to fly slowly and smoothly. But if the drone flys quickly or turns around, the scenes seems be out of focus and fuzzy. At this time, we would high recommend you to shooting in 2.7K@60fps.

 

Note: How to change the Tarsier mode between 4K and 2.7K?

 

You should change the recording resolution through the Caddx APP. The other method is just short press Power/Mode Button, as show in the image above. The mode is indicated by the color of the Mode LED.

 

Mode LED  -> Red -> 4K mode

 

Mode LED -> Green -> 2.7K mode

 

Jello and Vibration

The 85X drone is tuned carefully to avoid vibration and it should be no jello on the video. BUT, but if you fly it outdoor and sunlight, a ND filter is MUST. ND8 Fliter to get a better footage and eliminate the Jello effect. ND Filter-Light reduce but no color cast.

Why You Need ND Filters for Shooting Video (ND Filters Explained)? We find a video on YT to explain this issue. Start at 6:25. Here is the explaination:

 

PROPS OUT

The Beta85X drone also comes with "props out" by 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.
