BetaFPV F4 Brushed Flight Controller FrSky RX + OSD

  • Sale
  • $42.99


 This F4 board has an advanced F4 processor, which helps the overall flight characteristics to be smoother, faster, and help gain an advantage when flying acro in adverse conditions such as a light breeze or gusts of wind. With the TX1 controller, you can control the VTX, AKA smart audio.

Here is a review video made by Mr. ShutterBug.
A smooth and thrilled flying in the forest and detailed explanation of F4 brushed FC.

 

BETAFPV F4 brushed FC board bring a new era in FPV whoop technology. STM32F411 100MHz high-performance MCU, 30A lower resistance MOSFETs, SPI Frsky Rx, Build-in Betaflight OSD and polar reversed protection. All of these is backed by the same reliability and warranty on all BETAFPV FC boards.

 

High-performance ST Microelectronics ARM Cortex-M4 core F411 100MHz CPU (safely overclocked to 120MHz). Okay, I am the second high-performance whoop board in the world.

 30A continuous drain current MOSFET. Lower to 8.5mΩ inner resistance value (4.5V). It has a noticeable power improvement in low battery voltage status or with 8x20/8.5x20 motors.

TX1 is available for VTX control AKA smart audio. You could change VTX settings such as channel and output power in your Betaflight OSD or using your Taranis LUA Script. Here is the diagram when using the TBS Unify PRO Nano 5.8G VTX. 

Polarity reserved connection protection. Battery polar reserved connected. Bomb. This issue will never happen.

KEY FEATURES

  • The world's first compatible BetaFlight OSD, FrSky Rx, BetaFlight firmware, born for acro flight controller for the Micro Whoop or Blade Inductrix quadcopter.
  • Fully programmable through Betaflight, using the onboard USB port, tune all the parameters, PID's, and rates to your perfect settings
  • Designed to work with current Tiny Whoop or Blade Inductrix setups
  • Built-in SPI Frsky D8 protocol native receiver, compatible with almost ALL Frsky radios(e.g. Taranis X9D/X9D Plus/X7) or Frsky compatible transmitter module
  • The flight controller board comes pre-flashed with Betaflight firmware, and pre-soldered 55mm power cable pigtail with JST-PH 2.0 connector, AKA PowerWhoop connector.

  • Weight: 3.7g 

BetaFlight OSD

Betaflight OSD (on-screen display) is integrated into BETAFPV F4 brushed flight controllers that shows important flight data on your FPV feed, such as battery voltage, current draw and much more. You can even use it as a menu to change your quad’s PID, rates, filters and other settings. 

How would you an OSD with the AIO cameras?

There is a video in and out on the FC itself, labeled CAM and VTX as shown below. There should be a video in and out on the AIO camera, like BETAFPV H02 etc. If not, you would have to modify the camera for sure but it would totally be worth it. There are some examples.

BETAFPV H02 Camera, FX806TC, VM275, FX805, TX900TW, Eachine XT02 etc aio camera vtx are available to use the OSD function.

Tips: There is no current sensor on the FC boards. So the amperage value on the OSD is invalid.

Status LED

There are 3 LEDs on the bottom of the board to indicate the status, including Receiver LED ( Green), FC Status LED ( Red ) and FC Power LED ( Blue ).

SPI Frsky Receiver

Currently, the built-in Frsky receiver is compatible with Taranis, Taranis Plus, X9E, Horus X12S, XJT Modules with International Firmware (in D8 mode). Pay attention, this is an SPI connection receiver. In Betaflight Configuration, it should be set as FRSKY_D receiver in SPI RX mode.

Binding Procedure

The binding procedure is reversed as usual. No need to click the bind button when powering on.

  • Power on the board, either by connecting the battery or USB power. Then the green receiver LED start to flash.
  • The second step, click the bind button for 3s. Then the green receiver LED will be solid on. This means that the receiver is in bind mode and you could start to bind your radio transmitter.

For detail procedure of binding, please check the SPI Frsky Receiver Binding Manual.

Some pilots would complain that it is definitely not a long-range FC. It loses signal with my transmitter far too often and for what appears to be no reason. This issue is often caused by the location of the antenna. You should keep the antenna away from the FC board to get a stronger signal. For example, run the signal upwards.
