Item #:RP4S1

Synthesized receiver gets rid of the inconvenience of using the crystal. Receivers with crystal still use the technology of 1970's which have to switch the frequency by changing the crystal. Users have to bring dozens of crystal to flying field. In addition, every changing of the crystal may damage the electron devices. While it is only need to push the button, you can switch to any channel with synthesized receiver.

Every transmitter and receiver has production tolerance inevitably. But the production tolerance of the crystal affects it most. Even the most precise crystal has the tolerance of 1-2KHz, and sometimes it will be 4KHz. This is a big tolerance to a 10KHz narrow receiver. Synthesized receiver will correct the tolerance because it can automatically follow the frequency tolerance. It is what will make R/C receiver has the best performance.
With Corona's technology in manufacturing R/C products, RP4S1 4CH Single conversion receiver becomes the smallest in the world. Do not only focus on its small size. Its high-performance will surprise you.
