Before throwing away damaged or old LiPo batteries, you should first drain them completely until there is no charge left. In this article I will show you how to build a battery discharger using high power resistors.
There are many reasons why you want to discharge LiPo batteries. Maybe you have fully charged LiPo left after a flight session, or maybe you want to discharge the battery completely for disposal. In this article I will show you a few simple ways to discharge your LiPo batteries.
During the latency testing on the Frsky X-Lite, we discovered some interesting results. There is delay in the gimbals, (how often the gimbal value is being updated), and additional delay caused by OpenTX’s sample averaging.
The inevitable question for RC hobbyists is how to get rid of old or damaged LiPo (Lithium polymer battery). There are tons of videos online showing how dangerous LiPo batteries can be if not handled correctly, causing explosions and fire. In this guide we will show you how to dispose damaged and old LiPo batteries safely.
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 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.
The lack of explanation of the settings in FPV cameras often leaves users wondering what they actually do, and how to achieve the desired camera performance. In this post I will try to explain the different settings in FPV cameras and how they affect image quality.
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.
You can use any radio transmitter (TX) wirelessly with FPV simulators such as AccuRC, Liftoff, Velocidrone and DRL thanks to the latest feature in Betaflight 3.4. I will show you how to set it up in this tutorial.
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.
There are settings you can play with in BLHeli_32 to achieve better performance on your mini quad. In this article I want to share the settings in BLHeli_32 configurator that have given me the best result.
