FPV antenna is the deciding factor that determines the range and signal strength of your FPV system. This guide will explain the basics of 5.8Ghz antennas used on mini quad VTX and VRX, and hopefully it will help you choose the best FPV antenna.
Flashing or updating Betaflight firmware on flight controllers is simple, in this tutorial I will show you the steps and how to troubleshoot problems during flashing.
The Holybro Kakute F4 and F7 flight controllers now support Ardupilot firmware for more advanced and reliable GPS capability. Features include Return to Home, GPS Way-Point and Position hold etc. In this tutorial I will show you how to flash Ardupilot firmware on the Kakute F4 and F7 FC.
This tutorial shows you how to setup Betaflight firmware for the first time. You first need download the configurator, and connect the flight controller to a computer USB port. I will then go through each necessary setting with you for your first flight.
This article explains what Feed-Forward is
Setpoint Weight and Transition are, and how to tune it in Betaflight. “Derivative of error and measurement” are closely related to Setpoint weight / Feedforward, and they can give you very different flight characteristics.
There is so much new stuff to learn in Betaflight 3.4, I am sure it’s a bit overwhelming for a lot of people! In this tutorial I will try to explain how I tune my quad with the latest Betaflight firmware in the simplest way possible.
By simply updating the firmware on your Crossfire Micro TX module, you can increase the maximum output power from 100mW to 250mW. I will show you how in this post.
In this tutorial I will show you why and how to setup GPS in Betaflight for a quadcopter. I will also explain which is the best GPS module to get.
Lipo batteries degrade over time, sometimes this degradation results in dead cells. It seems to be a waste to throw the whole pack away because other cells might still be working. In this post we will show you how to make a working LiPo by combining the good cells from multiple damaged/defective batteries.
Capacitors can make your FPV video signal cleaner, and your mini quad fly better. In this tutorial we will explain what types of low ESR capacitor you should get and why low ESR is important, and where to install the caps in a racing drone.
Buzzer can help you locate your crashed drone, but typically it won’t work if the battery is disconnected in the crash. Here we will show you how to build a DIY lost model alarm with its own little built-in battery.
RSSI is a measurement of how good the radio signal is between your RC transmitter and receiver. It stands for Received Signal Strength Indication, and is an important safety feature. It helps avoid loss of radio signal, which could lead to unexpected crashes, damage to your quadcopter and other people’s properties.
