    Great First FPV Radio – Radiomaster Boxer

    Posted by Michael H. on 2026 Apr 27th

    Picked up the Radiomaster Boxer as my first FPV radio and have been using it with a simulator so far. It feels comfortable in the hands, and the sticks are smooth and precise. Setup was straightforward, and it worked right away in Liftoff. Even without flying a real drone yet, it already feels like a solid piece of gear.

    Smooth set up

    Even as a complete beginner, I had no trouble setting up and configuring it. Love the hard case and stick protector that come with.

    Supposed to be plug and play with my mobula8 drone. But it doesn’t work at all. Really desapointed.

    Great Radio!

    Posted by Adi L. on 2024 Aug 22nd

    Great radio. It is my first "modern" radio for FPV. I've used radios as long ago as 1970s. Love the ergonomics and the ease of use despite the many features it has.

    Amazing radio!

    Posted by Dana H. on 2024 Mar 27th

    This is my first radio, so take my opinion as you will. I bought this to start my training on the simulators and it's been awesome. Easy to setup, firmware updates were simple and my flying progression using it has been great.

    Really happy with the controller, and the service.

    Posted by David P. on 2024 Feb 29th

    This Boxer controller is working just great. For reference, this is my first "real" radio controller, having only flown traditional DJI consumer drones before. The gimbals feel smooth and are delight to use, all the switches feel solid, as with the potentiometers. The display is easy enough to use. In terms of adding a model to enable me to use this as a joystick for flying drones in a simulator on my PC, that worked effortlessly, and I also really enjoyed being able to map RC volume and brightness controls to the potentiometers. I'm a beginner, so my knowledge is limited, but from what I've gathered so far this Boxer is a fantastic controller that has massive amounts of capability, far beyond the little I've explored. Looking forward to getting to know it better. As for Rotor Village? Well, they were fantastic. They had my order shipped out very fast, and it arrived very quickly. Excellent all round.
