  • FrSky R-XSR pinout

    GND – ground wire +3,5-10V – positive voltage supply. R-XSR is rated up to 10V and powering it from 5V is the best option SmartPort – inverted S.Port pin (standard) – can be used directly with STM32F3 and F7 series SBUS – SBUS protocol output SBUS Input – for redundancy function only Uninverted SmartPort –…

  • FrSky Taranis Q X7 and X7S – is it still worthy?

    FrSky Taranis QX7 appeared on the market a few years ago and got quite a lot of popularity in its time. There were reasons for that:

  • Radio modules FS1000A and XY-MK-5V – pros and cons

    When looking for radio modules for your next Arduino project, you might have come across the couple named: FS1000A and XY-MK-5V. At first glance, they might look like the next best thing, but it’s not that simple. Before you start hacking anything with FS1000A and XY-MK-5V, read the following pros and cons: Pros: simple –…

  • Jumper T16 Review – better than FrSky?

    Jumper T16 RC transmitter messed around in the RC hobby in the last few weeks. FrSky wants to ban it since according to them it’s a clone of FrSky X10 (bullshit by the way). The question is: is Jumper T16 a good radio transmitter worth the money and what’s more important, is it a real…

  • QmuBeacon – open-source Arduino GPS locator/beacon drone is now public

    If too long didn’t watch: it’s a GPS equipped beacon/locator DIY system based on popular radio development boards compatible with Arduino: LoRa32u4 and ESP32 LORA32 working in 868/915MHz band using LoRa modulation. You put a beacon on anything you want to track: airplane, drone, car, boat, wife, husband and use Locator to get distance and…

  • How to bind FrSky receivers with OpenTX radios: Taranis X9D, Horus X10S and all the other

    In today’s “beginners” episodes: how to bind FrSky receivers with OpenTX radios. Almost all receivers: FrSky X8R, X4R, XSR, R-XSR, XM, XM+ but also “long-range” R series like R9, R9 Slim, R9 mini. With all the FrSky (and not only) OpenTX radios: Taranis X9D, Taranis Q7, X-Lite, Horus X10S, Horus X12 and so on… But…

  • INAV and Failsafe – especially for FrSky owners (but not only)

    You should not trust a guy on YouTube that says that he knows it all OpenTX “no signal” is not the best failsafe setting when FrSky S.BUS devices are used and why Than “Hold” failsafe setting might actually be a better option when S.BUS is used How to setup Failsafe in INAV to have the…

  • How to flash FrSky R9 Mini, R9 Slim and others with your radio

    FrSky is not making things simple with R9 long range system. New firmware appears quite often and there is no way to flash receivers over the air. You can use some PC software, passthrough from FC and things like that, but from my perspective, as long as you can get to the receiver itself, the…
