When it comes to radio receiver (RX) and transmitter (TX) protocols, 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 “concept” created by a RCGroup user “Ub3r”, that encodes DShot with PWM pulses. In theory there might be some benefits in using Proshot over DShot, but whether it makes a noticeable difference and overweight the downside, that’s another question.
In this article we will show you how to flash/update firmware on your Frsky receivers such as D4R-II, X4R-SB, XSR and XM+. This is useful when you have mismatched firmware that prevents you from binding, or you might simply want to update to the latest firmware version.
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.
One big confusion and misconception when it comes to FPV Cameras are the CCD and CMOS. Despite the huge amount of science and technical information behind the subject when comparing the two, we will only discuss the few basic things that matter to us as FPV hobbyists.
