We are sorry to announce that F3 Brushed FC is discontinued and will not be available for sales anymore. We recommend you buy its great alternativeF4 Brushed Flight Controller (Frsky Rx + OSD),F4 Brushed Flight Controller (SPI Futaba Rx + OSD)orF4 Brushed Flight Controller (DSMX Rx + OSD).

A smooth and thrilled flying in the forest and detailed explanation of F4 brushed fc.

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 of all FC boards.

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

30A continuous drain current MOSFET. Lower to 8.5m innerresistance value (4.5V). It has a noticeable power improvement in low battery voltage status or with 8×20/8.5×20 motors.

TX1 is available for VTX control.You couldchange 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 reversed connection protection. Battery polar reversed connected. Bomb. This issue will never happens.

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 Whoop Drone or Blade Inductrix setups
• No receiver integrated. So pilots could connect any receiver, like the TBS crossfire rx etc.
• 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 in 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 quads PID, rates, filters and other settings.

How would do an OSD with the AIO cameras?

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

BETAFPVH02 Camera, FX806TC, VM275, FX805, Eachine XT02 etc aio camera vtx are available to use the OSD function.

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

Assemble Guide

The mounting pattern of this board is compatible with all the Whoop Drone airframes, like the original stock Blade Inductrix frame or the Beta75 75mm frame. For other frames like Eachine E010 or E011, a little bit modify is need.

Package

• 1 * F4 OSD brushed flight controller ( 55mm PH-JST 2.0 power cable soldered)
• 4 *M1.2x4mm screws (Fit for stock Inductrix frame)
• 4 *M1.4x5mm screws (Fit for Beta75 etc 75mm frame)
• 4 * Anti-vibration ruber dampers
