How to choose motors for drones – especially 7-inch FPV quadcopters
One of the mistakes pilots makes when they build their first drone is they use too small motors. People think that if a motor works fine with 5-inch props, it will work with 7-inch props as well. After all, both have plenty of power and power is the key to everything. It’s not true. Power…

Race Day Quads Mach 1 with EMAX RS2 2306 2400KV
This year my friends and I stared a local FPV drone racing series. Nothing serious, just a couple of guys meeting once in a while and measuring times over the track. 100% amateur thing. After the second race, I’ve realized that I do not have a drone designed for racing: more than 400g without a…

How to make 868MHz or 915MHz dipole antennas for FrSky R9 or TBS Crossfire receivers
The correct length of 868/915MHz antennas used by FrSky R9 and TBS Crossfire is: From time to time FrSky has a big problem with cutting their antennas to a correct length. Good thing, you can make your own TBS Crossfire RX antennas for cheap! In this tutorial, you’ll learn how to build your very own…

Smooth 7-inch FPV drone – motor soft mounts, part 1
I have a theory that 7-inch FPV quadcopters fly “below expectations” due to frame resonance, I did not expect, so many pilots agree with it. We had nice talks in comments, I’ve learned a lot about stiffness and moment of inertia (that you Pierre-Louis). Many of you shared some of their tricks and ideas on…

Want to fly longer with a drone? Here is what you have to do!
I will keep it short: drones are not designed for a long flight. Sure, you can put bigger props, bigger batteries and make it lighter, but comparing to even simplest airplanes, there is nothing to compare. The conclusion is: try airplanes. They are cheap, simple, easy to fly with modern flight controllers and are much…

Fly at night with RunCam Night Eagle
Do you know, that with proper equipment you can fly your drone at night? In darkness? Without any lights? You only need a special camera that can see in the dark. I’m using RunCam Night Eagle that unfortunately is now discontinued and only Night Eagle 2 is available. Night flying itself? Pretty cool!

7 inch quadcopters fly like shit? Well, kind of, yes…
So, you got yourself a 7-inch quadcopter drone, you try to tune it, and you finally discovered that something is bloody wrong? Whatever you do, no matter how long you tune the PID gains and filtering, you can not get rid of jello and some strange vibrations? Welcome to the club mate! Apparently, scaling 5-inch…

Eachine TX805 5.8GHz 800mW video transmitter hands on
I have something like a personal problem with “the best FPV transmitter manufacturer”. It’s about ideology. So, when a few weeks ago I had to order a few 5.8GHz transmitters, I had something like a problem. With TBS Unify Pro on my “not wanted” list, the “wanted” list got somehow short.I do own a few…
