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.
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.
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.
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
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.
The media tends to use the term “drone” to refer to what we RC hobbyists call a “quadcopter” or “multirotor“. In this article I am going to share some of my ideas what drones and quadcopters are, and what the differences are between them. And how a quadcopter flies.
Quadcopters aren’t the most efficient aircraft compared to planes and fixed wings, therefore they tend to have relatively shorter flight time. I will explain the many factors that affect flight time on a drone, and how to keep you in the air for longer.
What drone pilots see while they are flying, are the low latency video from analog FPV cameras. To choose the best FPV camera for your multirotors, there are a few things to consider which we will discuss in this post.
I get asked frequently what gear I use and what multirotors I fly, so here is a list of mini quad and equipment that I regularly use. Note that I am not sponsored by any companies, I only recommend products that I have good experience with.
Here is a glossary of technical terms, abbreviations and acronyms often used in FPV, mini quad, quadcopter, racing drones and RC in general. Some jargon can be difficult to understand for beginners, hopefully this list of drone technical terms will help clear the confusion.
This tutorial explains the differences between RC Rate, Expo, Super Rate, as well as Throttle Expo and Throttle Mid, how these settings affect the performance of a quadcopter, and some tips on how to set them up.
