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 outfitted to deal with a variety of temperatures and difficult environments. With twin RF chips, the RP4TD provides two telemetry outputs at 100mW every, a major improve for lengthy vary flying. For these trying to push the bounds of two.4GHz FPV flying, this receiver looks like a perfect alternative.
Construct High quality
The receiver itself is compact and well-built.
The highest facet incorporates 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 because of its twin RF chains, the design stays impressively compact.
Nevertheless, the inclusion of longer antennas might have enhanced its enchantment for bigger builds, resembling 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 most effective 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?
Notice that true range doesn’t crucial improve vary however supposed to boosts reliability and hyperlink high quality, significantly with Gemini mode enabled.
The RadioMaster RP4TD Range ELRS Receiver is a major improve for FPV pilots looking for the utmost in reliability and efficiency. Its dual-chip design and strong construct make it a best choice for demanding flight situations.
Get the RP4TD Receiver from these distributors:
For these constructing bigger drones, contemplate getting some longer antennas for the most effective setup. For individuals who push their FPV flying to the extremes, the RP4TD is a worthy funding, making certain that your drone stays in fixed, dependable communication along with your transmitter.
