The standout characteristic of the RP4TD is its two separate SX1281 RF chips and TCXO (Temperature Compensated Crystal Oscillators). This design method the receiver is healthier supplied to deal with quite a lot of temperatures and difficult environments. With twin RF chips, the RP4TD gives two telemetry outputs at 100mW each and every, a vital improve for lengthy vary flying. For the ones having a look to push the bounds of two.4GHz FPV flying, this receiver turns out like a super selection.
Construct High quality
The receiver itself is compact and well-built.
The highest aspect includes a boot button and two U.FL connectors for the antennas. The 4 soldering pads are out there on either side of the receiver with transparent labels: 5V, GND, RX and TX.
Even though the RP4TD is significantly better than single-antenna EP1 receivers because of its twin RF chains, the design stays impressively compact.
Then again, the inclusion of longer antennas will have enhanced its attraction for better builds, akin to 7″ or 10″ drones. Nevertheless, prolonged antenna wires are readily to be had for the ones in want:

Set up
Putting in the RP4TD is as easy as any ExpressLRS receiver. The bottom line is to verify optimum antenna placement. To verify the most productive reception, positioning the antennas to steer clear of getting blocked simultaneous by means of any a part of the quadcopter is a very powerful. This separation is essential for keeping up a constant and dependable connection.
Conclusion: Is the RP4TD Proper for You?
Be aware that true range doesn’t essential build up vary however supposed to boosts reliability and hyperlink high quality, specifically with Gemini mode enabled.
The RadioMaster RP4TD Range ELRS Receiver is a vital improve for FPV pilots looking for the maximum in reliability and function. Its dual-chip design and powerful construct make it a best choice for not easy flight stipulations.
