This article explains what FC looptime is and how faster looptime might affect your quadcopter’s flight performance. We’ll also talk about gyro update frequency and ESC refresh rate which are equally important.

Resource Remapping is an awesome feature in Betaflight, it allows you to swap pins around on a flight controller. Resource Remapping is powerful, you can change motor order, relocate pins in case of ripped-off solder …

In this tutorial I will show you how to setup a switch on the Taranis to simply read out the voltage of the battery on your quadcopter.

I am very excited and scared at the same time with this project. I will be building a fixed wing and attempt to fly it in FPV. I have absolutely no idea and experience with …

Not only you can crash your drone mid flight when voltage drops too low, over discharging LiPo battery can also cause permanent battery degradation or even damage. To keep your batteries in good condition, it’s …

One of the most useful features of FrSky radio would be telemetry. Telemetry is designed to transmit in-flight data from the radio receiver back to the radio transmitter. These telemetry data informs the pilot what is …

Proshot is an ESC protocol that encodes DShot using PWM pulses. While it offers some theoretical advantages over DShot, whether it makes a noticeable difference—and whether those benefits outweigh its downsides—is still a matter of …

I will show you how to flash Frsky receiver firmware on your R-XSR, R9 Mini, XSR, D4R-II, X4R-SB, XM+ and some other RX. Updating RX firmware is useful when you have the wrong firmware that …

In this post we will have a look at the differences of mini quads running 3S and 4S lipo batteries. Many who are building their first mini quad might struggle in deciding which setup is …

Using screws that are too long is a common mistake among FPV drone builders. FPV drone motors only come with one set of screws while FPV drone arms might have different thickness can often causes …

A visitor asked me for advice how to start building a quadcopter after flying with a RTF (pre-built) drone. The flying experience and basic understanding with RC and FPV he has had will definitely help him with this …

It’s possible that you can brick your flight controllers due to human error (where FC doesn’t talk to computer anymore, just timeout or says connection fail). You might still be able to fly using that FC as normal, …
