Single Conversion Receiver RS810II Receiver CORONA never stops improving the receiving range. RS810II has improved the receiving range as far as 1.5Km (checking range on ground). If we use traditional technology, how big the receiver should be made to reach such a far receiving range? Further remote control distance means more reliable control. Even the reliability can compare beauty with PCM receiver. PCM receiver has good reliability because it uses CRC code to fill up the wrong codes which leading by shortage of receiving range. The signal will always seem to be fine ostensibly, but CRC code of PCM began to fill up “bad data cavity” which happens at times while exceeding half of the distance described by manufacturer. PCM code wastes a lot of time to receive more data to fill up the cavity of “bad data”. So usually we feel that PCM receiver has no glitch, while its response speed is less than PPM receiver. We make control distance be further so that receiver can locate in stable RF Electromagnetic Field, it will make the reliability of Corona receiver approach to PCM receiver. Meanwhile, its response speed will not be influenced. With improved circuit design, RS810II advances IP3 performance apparently, and it can even compare beauty with all famous brand receivers around the world. IP3 performance of a receiver is vital for serried R/C transmitters working at the same place. A receiver with lower IP3 will still working fine when 1-2 transmitter with adjacent channel working in the same time, but once open the third adjacent channel transmitter, the receiver will lose control immediately if it has poor IP3 performance. The light weight and small size of RS810II predominate in other receivers. Furthermore, we have moved the crystals of RS810II to side face, which really improves the reliability of replacing crystals. We have also improved DSP. It can make more strictly filter about received signals and eliminate glitch efficiently. You can put RS810II receiver in any place when you install it on whatever electric puddle-plane, 3D plane, glider or training plane. And don't worry the trouble which will be brought by changing CG. RS810II receiver has the structure of level inserted pin by special design and assorted with super thin electronic parts. The thickness of RS810II receiver is only 7.2mm which make the installation more convenient. Reliability, high performance and sale price, they are what CORONA can provide for you.
