This is a companion topic for our recent blog post on blog.unmanned.tech
In the latest blog post, we had a gander at the BetaFPV LiteRadio 4, a tiny transmitter that feels just like your favourite gamepad—ideal for those blessed with smaller hands or beginner pilots who prefer not to wrestle with complex settings. It’s compact, with built-in ExpressLRS support and a rather splendid internal battery, though you might find yourself longing for that removable option when it’s time for a mid-flight juice-up.
Our resident expert, Painless360, highlighted the practical upgrades: ten channels, extra buttons for your convenience, and the all-important Bluetooth, Wi-Fi, and USB-C capabilities. Perfect for those who appreciate the feeling of being in control without needing a degree in radio programming. However, if you’re the sort who craves custom stick tension, best to look elsewhere—this is no premium gimbal playground.
Battery life is respectable, offering around 4-5 hours at full power, but the internal, non-replaceable battery may raise an eyebrow or two among the more seasoned flyers, especially those prone to lengthy field sessions. On the upshot, it’ll charge quickly—ideal for those on the go, or those who just can’t be bothered to plan ahead.
In short, if you’re after a lightweight, user-friendly transmitter that won’t leave you crying into your tea, the LiteRadio 4 could be just the ticket. However, for the hardcore pilots out there, this one might feel a tad too cute and cuddly for comfort.
