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.
When it comes to radio receiver (RX) and transmitter (TX) protocols, confusing acronyms are often used: PWM, PPM, SBUS, DSMX etc. In this post we will explain the differences of these RC TX and RX signal types.
Proshot is a new ESC protocol that encodes DShot using PWM pulses. In theory there might be some benefits in using Proshot over DShot. However whether or not it makes a noticeable difference and overweight the downsides, that’s another question.
I will show you how to flash Frsky receiver firmware on your R-XSR, XSR, D4R-II, X4R-SB, XM+ and some other RX. Updating RX firmware is useful when you have the wrong firmware that prevents you from binding, and getting the improvements and bug fixes in the latest firmware.
In this FPV camera latency testing I will share my results on over 20 cameras, also my method of testing camera delay. FPV camera lag has impact on a pilot’s reaction time in flight, and it is one of the most important considerations in selecting FPV cameras.
Antennas for FPV can be categorized by their polarization: linear and circular. In this article we will discuss the differences between linear and circular polarized antennas.
Removing header pins on a flight controller or circuit board in general could cause damage to the hardware if it’s not done properly. Here I will show you a couple of examples how I do it safely and easily.
The gain of an antenna could change the radiation pattern, and it reflects what the maximum range is going to be for the FPV antenna. In this article we will discuss how antenna gain affects range, and the pro’s and con’s of high gain antennas.
George Chatzisavvidis is very kind to share with us how he enabled OSD menu for the Fatshark Diversity module and goggles button support, by adding a minimOSD.
DShot is a new communication protocol between flight controller (FC) and ESC, substitute to Oneshot and Multishot. DShot stands for Digital Shot.
This is a story of a FC that died right after I finished the build, and there came another FC to the rescue. Thank you Newbeedrone, thank you BeeFlight FC!
Recently I tested the RE1 F4 FC and mPB (PDB) from BrainFPV. When I looked up the FC/PDB combo, I found several ads stating that the RE1 is the most advanced racing flight controller ever made! Wow that’s a big statement, guess we will find out in this review.
