For anybody trying to get into flying FPV drones, the very first thing I all the time advocate is getting a radio and training in a simulator. Not solely does it provide the obligatory coaching, but it surely additionally helps decrease prices. The brand new LiteRadio 2 SIM from BetaFPV might be the most affordable radio out there for that objective. On this evaluate, we’ll check out its options, the way it works, and whether or not it’s the suitable starter radio for you.

What’s Particular Concerning the LiteRadio 2 SIM?
The BetaFPV LiteRadio 2 SIM is at present essentially the most reasonably priced radio you should purchase particularly to be used with FPV simulators.
Sure, you might strive utilizing a keyboard or a recreation controller with sims, however I strongly advise towards it (as defined on this information). They don’t supply the precision you want, and also you’ll simply need to relearn all of your muscle reminiscence as soon as you turn to an actual radio later.
The LiteRadio 2 SIM is right if you wish to get the total advantages of FPV simulator coaching however aren’t able to spend money on a full-featured radio but.
Nonetheless, its low value comes with a limitation: the LiteRadio 2 SIM has no RF transmission module and no module bay. This implies you can not use it with an actual drone — it’s strictly for simulator follow. Should you resolve to fly actual drones later, you’ll want to purchase a correct radio.

Design and Ergonomics
I reviewed the unique BetaFPV LiteRadio 2 about 5 years in the past, and this new SIM version has the very same kind issue and design.
The LiteRadio 2 by no means grew to become my day by day driver as a result of it’s a really primary finances radio — the gimbals are small and don’t really feel as clean as higher-end transmitters. That mentioned, it’s not a deal-breaker. For coaching functions, it does the job completely, and it’s nonetheless a large enchancment over utilizing a keyboard or gaming controller if you wish to get essentially the most out of FPV simulator follow.
For rookies, a very powerful factor is constructing muscle reminiscence and stick management, radio ergonomics shouldn’t be actually the highest precedence at this stage. As you progress and transfer on to actual drones, you’ll finally need a higher-quality radio with higher gimbals and a form that fits your arms.
The purpose of this radio is to allow you to strive FPV in a simulator on the lowest doable price. Should you resolve FPV isn’t for you, you’ve solely spent $18 — no huge deal. It’s additionally a fantastic possibility for colleges, workshops, or coaching camps the place numerous radios are wanted with out breaking the finances.
Because of its compact and minimalist design, the LiteRadio 2 SIM can also be tremendous light-weight, making it comfy for hours of follow. It’s particularly beginner-friendly for youthful pilots or anybody frightened about hand fatigue.
On high, you’ll discover 4 toggle switches:
- SA and SD: 2-position switches
- SB and SC: 3-position switches
Some simulators allow you to map these switches to helpful capabilities akin to arming/disarming, switching flight modes, or resetting the sport — very useful for practical coaching.
Energy and Connection
The LiteRadio 2 SIM is powered completely through the USB-C cable — no battery required. Meaning you’ll by no means run out of energy throughout coaching, and you’ll simply maintain training so long as you want.
In my testing, the radio was plug-and-play with my laptop, which made setup extremely handy.
FPV Sim Compatibility
The LiteRadio 2 SIM works on Home windows and macOS, supporting all the favored FPV simulators on Steam, together with Liftoff, VelociDrone, Tryp, Uncrashed, and extra. You’ll be able to study these simulators in my detailed FPV simulator information: https://oscarliang.com/fpv-simulator/
It’s additionally appropriate with Android and works with the free FPV Skydive sim, which I examined personally on my cellphone.
Find out how to Use
Energy On
To energy the radio, merely join the USB-C cable. The radio activates robotically — no must press the ability button. The LED on the ability button will flip inexperienced and flash slowly.
Additionally be sure to have throttle all the way in which down and go away the suitable stick centered earlier than connecting USB.
Stick Calibration
After I first plugged the radio into my PC, the Liftoff simulator robotically detected it as “BetaFPV Joystick” — no drivers required, which was good.
Nonetheless, I bumped into a difficulty throughout calibration: the sticks had no decision, leaping straight between 0 and 100 as a substitute of transferring easily.
I mounted this by calibrating the sticks contained in the radio itself. The handbook suggests this shouldn’t be obligatory (because it’s supposedly factory-calibrated), however in my case it was. Fortunately, the method is straightforward:
- Join the USB cable to energy on the radio.
- Maintain down the ability button for 3 seconds till the LED flashes purple twice quickly.
- Heart each sticks, then press the ability button once more — the LED will flash purple 3 times quickly.
- Transfer each sticks in a full 360° circle a few instances.
- Heart each sticks once more, then press the ability button one final time.
That’s it — the radio is now calibrated. After this, carry out the calibration course of inside your FPV simulator, and you have to be good to go.
Switching Modes
The LiteRadio 2 SIM affords three modes, relying on the platform you’re utilizing.
For 99% of individuals, you’ll probably be flying on one of many FPV simulators out there on Steam. In that case, the default Joystick Mode is all you want — simply plug it in and fly, no adjustments required.
If you wish to use the radio with an Xbox (for sims like Aerofly RC 8 or DJI Digital Flight) or in Dongle Mode (for Phoenix RC 6.0), observe the directions supplied within the handbook to change modes.
Flip Off LED
You’ll be able to flip off the LED on the ability button by merely urgent it. This doesn’t energy off the radio — it simply disables the sunshine.
Enhancements
Whereas the LiteRadio 2 SIM could be very practical, I really feel BetaFPV might enhance it in a couple of areas:
- Ergonomics & Measurement – Making the radio barely bigger, with a form extra just like standard FPV transmitters just like the Radiomaster Pocket, T20S, or Boxer, would make the transition smoother when rookies improve later. Since this radio is especially for indoor sim coaching, compactness isn’t an enormous precedence. However I believe BetaFPV reused the prevailing LiteRadio 2 shell to maintain manufacturing prices low (creating a brand new injection mould is dear).
- Coach Port – Together with a coach port would have been incredible. It could enable the LiteRadio 2 SIM for use as a scholar radio linked to an teacher radio with full RF capabilities — good for real-world FPV coaching situations.
- Cables – In right now’s world, a USB-C to USB-C cable makes extra sense than USB-A to USB-C. Ideally, each ought to be included to cowl all use instances.
Firmware Replace
The LiteRadio 2 SIM’s firmware will be up to date utilizing the BETAFPV Configurator, out there right here:: https://github.com/BETAFPV/BETAFPV_Configurator/releases
Conclusion
The BetaFPV LiteRadio 2 SIM is likely one of the most cost-effective and best methods for rookies to start out coaching with FPV simulators. It’s reasonably priced, plug-and-play, and well-suited for people with tight finances, or organizations that want a number of radios, akin to colleges, coaching camps, or group occasions.

That mentioned, keep in mind that this radio can’t be used with an actual FPV drone.
