Quick Look: FrSky R9 mini

Let's take a quick look at the FrSky R9 mini, an ultra-tiny long-range RC receiver that works with the FrSky M9 module to give a claimed range in excess of 10Km. I will be using this receiver as part of the sub-250g long-range FPV RC plane project so stay tuned for a full review and its inclusion in the build-videos.
