So you want to flash Frsky RX firmware, but too lazy to take your quad apart? You can flash it through your flight controller, just like how you flash your BLHeli ESC’s using FC pass-through.
It’s important to setup failsafe properly on your mini quad for maximum safety and preventing fly-away. In this tutorial I will explain what failsafe is, and how to set it up in Betaflight as well as on your Taranis TX radio transmitter and receiver.
The FrSky’s R9 receiver is designed to work with the Frsky R9M long range module, however it was just a bit too big for mini quads. Therefore Frsky made a smaller version, the R9 Slim, which we will check out in this review.
If you accidentally damage your 2.4GHz receiver antenna in a crash or by spinning propellers, don’t worry! You can easily fix it without buying a whole new receiver or replacement antenna. And there are considerations about the length of the antenna you should know about.
SPI_RX is a new communication protocol between the flight controller and receiver using SPI BUS. We will explain what SPI_RX is, and the advantages over traditional serial RX protocols such as SBUS.
For long range flying, RC links is just as important as your FPV video link. In this review we will have a look at some long range RC options: the Frsky R9M and TBS Crossfire. These are the two most popular TX modules compatible with the Taranis X9D and QX7 transmitters.
FPort is the latest RC serial protocol that brings a few improvements over the existing RX and telemetry protocols. This tutorial will explain the advantages of FPort, and how to set it up on Betaflight flight controllers for your mini quad.
There are many transmitter options available for mini quads. While many would recommend a high end transmitter, beginners might choose to save a bit of cash on selecting a TX. This is completely understandable when you don’t know if the hobby is really for you, and this is where the FlySky range comes in.
The Frsky R-XSR receiver is the smallest RX that can do 16 channel SBUS and SmartPort telemetry. It’s the go-to option now and replaces the XSR or X4R-SB for Frsky TX users who own a Frsky transmitters such as the X9D and QX7.
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 prevents you from binding, and getting the improvements and bug fixes in the latest firmware.
FrSky XSR-M is a smallest SBUS/CPPM Radio Receiver offering full range and Smart Port telemetry recently released.
