The standout function of the RP4TD is its two separate SX1281 RF chips and TCXO (Temperature Compensated Crystal Oscillators). This design means the receiver is healthier geared up to deal with a variety of temperatures and difficult environments. With twin RF chips, the RP4TD affords two telemetry outputs at 100mW every, a big improve for lengthy vary flying. For these seeking to push the bounds of two.4GHz FPV flying, this receiver looks like a really perfect alternative.
Construct High quality
The receiver itself is compact and well-built.
The highest facet includes a boot button and two U.FL connectors for the antennas. The 4 soldering pads are accessible on each side of the receiver with clear labels: 5V, GND, RX and TX.
Though the RP4TD is notably bigger than single-antenna EP1 receivers on account of its twin RF chains, the design stays impressively compact.
Nevertheless, the inclusion of longer antennas may have enhanced its attraction for bigger builds, equivalent to 7″ or 10″ drones. Nonetheless, prolonged antenna wires are available for these in want:

Set up
Putting in the RP4TD is as simple as any ExpressLRS receiver. The bottom line is to make sure optimum antenna placement. To make sure the very best reception, positioning the antennas to keep away from getting blocked simultaneous by any a part of the quadcopter is essential. This separation is important for sustaining a constant and dependable connection.
Conclusion: Is the RP4TD Proper for You?
Observe that true variety doesn’t obligatory enhance vary however supposed to boosts reliability and hyperlink high quality, notably with Gemini mode enabled.
The RadioMaster RP4TD Range ELRS Receiver is a big improve for FPV pilots in search of the utmost in reliability and efficiency. Its dual-chip design and strong construct make it a best choice for demanding flight circumstances.
