BETAFPV 2.4G ELRS Lite Receiver

BETAFPV Lite receiver is based on the ExpressLRS project, an open-source RC link for RC applications. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.

Tower Antenna or Flat Antenna
New lite receiver with a flat antenna features a 3mm extra-thin board and 0.53g lightweight, which requires less assembly space on drones with limited space. Besides, solid flat antenna without irregular parts can withstand crashes, making the receiver not so fragile.

Whatever tower antenna or flat antenna, both versions perform well in control, range and stability, bringing a good flight experience to pilots. Below chart is the basic information for two antennas. It is shown that both antennas have almost the same performance in gain. However, the efficiency for flat antenna is better than tower antenna. In spite of that, tower antenna and flat antenna V1.1 can reach about 600 meters by equal conditions.

Flat Antenna V1.0 & V1.1
The ELRS Lite Receiver flat antenna V1.1 is coming to see you again. Range issues and failsafe at around 100 meters have been resolved compared with V1.0. Now, the V1.1 flat antenna receiver can reach 600 meters with BETAFPV Moxon TX Antenna (using BETAFPV Nano TX module).

Previously, the flat antenna V1.0 led to the failsafe at around 100 meters with an RSSI of -95dBm of this receiver, which did not reach the expected range compared with the beta version. However, it works great for indoor whooping and racing.
