FlySky FRM302 & FTR16S AFHDS3 – The Ultimate 2.4GHz Long-Range Radio System
ImmersionRC Ghost is the new long-range 2.4GHz radio system that is getting the most traction in the media in the last few days. However, IRC Ghost is not the first 2.4GHz SX1280/SX1281 LoRa based radio system that has hit the market. FlySky FRM302 TX module and FlySky FTR16S AFHDS3 receiver are available since May 2020,…

Bidirectional DSHOT & RPM Filtering – Is It Really Necessary?
There is a group of people who think that the RPM Filter is the best thing to happen to flight controllers and quadcopters since the sliced bread. Perhaps. I’m more inclined to believe that RPM Filter is just an example of good functionality. But it will not be about that, so let’s go back to…

ZOHD Drift Review – a smart FPV glider
Airplanes are fun, and I like to fly them. Unfortunately, most RC airplanes have a severe flaw: they are big, bulky, and traveling with an FPV airplane can be a pain in a posterior. Sure, some can be disassembled into a few smaller parts, but usually, those parts are not small, and assembling the airplane…

EmuFlight Kalman Filter Tuning
The most distinctive feature of the EmuFlight flight controller software is it’s gyro Kalman filter. Yes, the same filter that some people name the dynamic PT1, doubt that it works or calls it magic. I will not discuss if the EmuFlight Kalman works and how it works (it works tho, I have enough time in…

Beitian BN-180 GPS Module Troubleshooting
Beitian BN-180 is one of the most popular small, and cheap GPS modules used with INAV on airplanes, or on Betaflight on quadcopters. Most of the time, they work just fine, but I discovered that they could make problems from time to time. Here is a shortlist of possible issues and solutions for Beitian BN-180…

How to setup INAV on a rover
INAV finally allowed to use INAV and INAV compatible flight controllers to be used on rovers and boats. Finally, INAV supports not only flying vehicles. Bear in mind, that the rover and boat support is not full, and some functionalities might not be working like expected. What works:

Ritewing Mini Drak Center of Gravity
Ritewing Mini Drak is a fantastic R/C airplane. Fast, stable, and thanks to smooth lines and negative swept wing, it looks great. Thanks to negative wing sweep and a long nose, it has a very unusual center of gravity (CG). Mini Drak’s CG is located almost at the leading edge of wings. The Center of…

Diatone Hey Tina Whoop162 with FalcoX
I will be very frank with you: I do not like those tiny whoops. You know, 2″ and smaller propellers, plastic frame, a camera on top. You know, those almost cheapest FPV drones you can get. I’m saying that builds like BetaFPV 65X or Emax Tinyhawk are bad. I just do not like to fly…

STM32 F1, F3, F4, G4, F7 and H7 flight controllers
Currently, almost all flight controllers we use on our multirotor FPV drones and airplanes are powered by microcontrollers from an STM32 family. When we say about flight controller families or generations, we refer to them by the family of the MCU. For example: F1 flight controllers are no longer supported or You should get F7…
