The BetaFPV LiteRadio 2 is a basic and affordable radio. It has almost everything you need to fly a micro quad, yet with all the unnecessary features removed, making it extremely easy to use. It’s a great little radio that you can take everywhere.
Update (Apr 2022): There’s a new version – LiteRadio 3 Pro.
Where to Buy?
Closer Look at the LiteRadio 2
The LiteRadio 2 has the shape of a gaming controller. It’s comfortable to hold, and the anti-slip texture on the handles allows for a solid grip.
Gimbals and Switches
The small form factor determines how you are going to hold this radio, it works really well for “thumbers”, but perhaps too small for “pinchers”. (Thumbing and pinching, these are two ways of holding the sticks)
The gimbals on the LiteRadio 2 are not the highest quality, not as smooth as the hall gimbals on full size radios, but they get the job done. The stick travel (range of motion) is also not as long as the full size radios, but i don’t think it’s a big deal for micro quads, you don’t need all that precision.
However, I do get some jitter with the the centre stick values jumping between 1496 to 1504 (when I am not touching the sticks). It doesn’t bother me as I am using this radio mostly on micro quads and tiny whoops. I simply set “deadband” value to 5 in Betaflight, and it seems to work fine.
The stick ends can be removed, and you can also adjust the length of the stick.
There are four switches, which are already configured as channel 5, 6, 7 and 8. Two of the switches are 2-position, and the other two are 3-position.
As you can see, you can’t change gimbals tension, but you can change stiffness of the throttle stick.
It’s interesting to see that they added some weight inside the radio, the extra weight does make the radio feel slightly less like a toy.
Battery, Charging, USB Port
It comes with a 2S 350mAh LiPo battery, and you can charge it through the USB port. It’s quite a small battery, lasts about 2-3 hours per charge. Maybe as a DIY hack, we could replace the metal weight inside the radio with more batteries for longer run time :)
Also I think they could use 18650, which might be a bit safer than using a LiPo inside the radio. Although I’ve used LiPo in radio in the past and never had any safety issues.
There is a micro USB port for charging the battery, and you can play FPV simulators as well by connecting it to your computer. For me it was “plug and play”, I didn’t have to mess with drivers at all.
Next to the USB port, is the trainer port, which I don’t normally use.
Protocols and Range
The LiteRadio 2 supports 3 protocols: Frsky D16 FCC, D16 LBT and D8, covers almost all the popular micro FPV drone models.
Range is quite similar to my Radiomaster TX16S (with multiprotocol module) when testing with Beta65X HD which has a built-in Frsky SPI receiver. Note that the LiteRadio has a PCB style antenna inside the radio, it’s not as good as a full size antenna, so don’t expect amazing range from it. With that said, I’ve been flying my tiny whoops in the house without any failsafe.
It doesn’t have a speaker, but it does have haptic feedback (a vibration motor). If you signal gets too low the radio will vibrate.
Yes, this tiny little radio runs OpenTX!
Because it doesn’t have a screen, if you want to change radio settings, you’d have to connect it to your computer, and do that through OpenTX Companion. Here is how: https://bit.ly/3cgeHYT
But to be honest, I haven’t had the need to use OpenTX Companion yet :) The LiteRadio works just fine out of the box, but it’s good to know the options are there.
The BetaFPV LiteRadio 2 is not for everyone, but if you are looking for a cheap, simple and small radio that works well for micro drones, this is indeed a good option. I think it’s also great for beginners as their first radio, because it’s easy to use, and it’s cheap.
You can’t use Crossfire on this radio as it doesn’t have a module bay, and you cannot easily change radio settings without going to your computer.
But hey, It works with Frsky receivers, compatible with FPV simulators, charging through USB, supports OpenTX, ONLY $40, what more can we ask for :D
Get it from:
- Decent gimbals, not as good as the ones on full size gimbals, but still much better than the ones on toy grade radios
- Trainer function
- Supports FPV Simulator
- Extremely portable
- One of the cheapest radios you can buy
- USB Charging
- Supports Frsky D8 and D16 – up to 8 channels for flight modes and other functions
- The radio has no low battery warning, if you forget to switch off the remote control, you could over discharge LiPo
- OpenTX features minimal
