The?BetaFPV LiteRadio 2?is an 8-channel OpenTX budget radio control transmitter. For only $40, can it be any good? It certainly does not match up to a full-size radio, but when you consider value for money the LiteRadio 2 makes a compelling argument.
The LiteRadio2 is currently offered in Bayang and FrSky protocol versions. The Bayang protocol is used by lots of toy-grade drones that often ship with small, terrible controllers. BetaFPV's LiteRadio 2 would allow you to control these toys with much better precision and ergonomics than the controllers they ship with if you chose that option. If you choose the FrSky version instead, you gain a controller that can pair with?many hobby- and pro-grade models and radio receivers.
Most of the sticks are spring-loaded and will automatically return to center, but a stick without a spring is needed for maintaining throttle position. The Mode 1 option has the spring removed from the up/down direction on the right hand stick. For Mode 2, the removed spring is on the left stick. Mode 2 is by far the most common configuration. The FrSky D16 uses ACCST 1.0, so it's compatible with all older receivers and micro quads-but not with receivers that have the?ACCST 2.0?upgrade. For this review, we're looking at the FrSky Mode 2 version.
There are a few features that stand out in the LiteRadio 2 and help to make it a very strong option.
