Buzzers with built-in battery can help locate your crashed RC model even after the main battery is ejected or dead. We will compare a few popular options to find out which is the best for you.
In this tutorial I will show you how to check the Betaflight firmware target for your flight controller. Different FC might use different Betaflight firmware targets. if you flash the wrong firmware to your FC, you could “brick” the board and unable to connect or flash it again.
I will show you how to to test motor spin direction after connecting it to an ESC. You want to make sure all the motors on your quadcopter rotate in the correct direction. Otherwise it will flip over (or freak out) when you try to take off.
I sometimes rush to fly my quadcopters right after I finish building them. Unfortunately there were times the drone didn’t take off as expected due to misconfiguration. I even had magic smoke a few times because of faulty parts and short circuits.
Learning my lessons the hard way, I have come up with a list of things to check every time I build a new mini quad. Hopefully this guide will help you avoid surprises when powering on for the first time, and make sure your drone is ready for a safe maiden flight.
In this article we will compare the best quadcopter simulators for FPV. Drone simulators have been around for decades, but only recently we’ve begun to see more options designed specifically for drone racing and FPV freestyle, some of which are even free!
LC filter is one of the most basic filters in electroincs, which comprises of just one inductor and one capacitor in its simplest form. This circuit is widely used by FPV hobbyists to suppress noise in power created by ESC and motors. Read More
In this tutorial we will show you how to add RGB LED to a mini quad and setup through Betaflight, so that the colour of the LED can be controlled by the flight controller.
There are two ways of calibrating ESC in your quadcopter: using the “motor tab” in Betaflight Configurator or BLHeliSuite Configurator. You don’t need to do ESC calibration if you are using DShot protocol, for other ESC protocols you need to calibrate your ESC’s.
This tutorial shows you how to troubleshoot and fix a quadcopter that doesn’t arm. I will also explain the common problems that prevent a mini quad from arming with Betaflight.
This tutorial explains the basics of quadcopter hardware, what each component does and how they connect with each other. There is a lot to cover, make sure to check out the links for more information on each quadcopter component.
It’s important to setup failsafe properly on your mini quad for maximum safety and preventing fly-away. In this tutorial I will explain what failsafe is, and how to set it up in Betaflight as well as on your Taranis TX radio transmitter and receiver.
