The RadioMaster RP series receivers are built-in a TCXO (temperature-compensated crystal oscillator) now, which ensures reliable, stable, and accurate signal reception, allowing for superior performance in demanding environments and enhancing the flight experience.

The RP1 and RP2 2.4GHz ELRS nano series receivers are open-source receivers based on ExpressLRS.

The Nano receivers, first developed by Jye Smith from the ExpressLRS development team, feature ESP8285 MCU and SX1280 RF chip. The RP1 has a UFL antenna socket for full-range antenna use. The RP2 has a built-in ceramic antenna which is super light and small in size and ideal for racing.

The RP1 and RP2 feature WIFI built in so you can upgrade firmware by WIFI and configure the Receiver via the built-in WebUI with your PC or mobile phone.

Due to the low-latency and high-refresh-rate RF module, the RP1 and RP2 are ideal for FPV races or Long Range. Suitable for Whoops, drones, and fixed-wing models due to the ultra-light and Nano size, these receivers can fit just about anywhere!

TCXO (temperature compensated crystal oscillator)

The TCXO ensures high stability and accuracy in frequency control, compensating for temperature variations. This results in consistent and reliable signal reception, even in extreme temperature conditions. It also reduces frequency drift over time, providing long-term frequency stability and preventing signal degradation. Click to learn more about the TCXO.

      Good option for softening a college apartment bed
      I moved into a college apartment where the bed felt like it belonged in a dorm from years ago—flat and stiff. Instead of dealing with it, I tried this topper, and it added a cushiony layer right away. The surface feels much more forgiving when I fall onto the bed after studying or hanging out with friends. It has just enough padding to take away that board-like feeling without making the bed sag. Another thing I noticed is how breathable it is. I expected something this thick to feel warm, but it actually stays cool even if I stay on one side for a long stretch.

      Makes an older family mattress feel brand new
      There’s an older mattress in my place that everyone avoids because it feels too worn in the middle. Instead of replacing it, I decided to give this topper a shot. Once it settled on the bed, it added a thick cushioned layer that helped level out the whole surface. Lying down feels smoother, and the middle no longer dips the way it used to. The fabric feels cool when you touch it, and it keeps that same feel even after staying on it for a while. I thought a thick topper might hold warmth, but this one keeps the air moving enough that the bed stays comfortable throughout the night.

      Helpful upgrade when staying between short-term housing
      Laying it out was quick, and once it settled, the bed instantly felt gentler on the shoulders and hips. The padding feels thick without being bulky, and it molds just enough so that you feel supported without sinking. The airflow is surprisingly good. Even after lying still for long periods, the surface never turns warm or clammy. That was important since the mattress underneath didn’t have much ventilation.

      Super comfortable
      Color: Green Bamboo(2300gsm), Size: Queen
      this mattress topper completely saved my bed. It is super thick and soft, but still gives enough support so you don’t feel totally stuck. The cooling cover actually works pretty well and doesn't trap heat like other memory foam I’ve tried in the past. It was also really easy to put on and the deep pockets keep it from sliding around at night. Very happy with it!
