Among the range of Corona receivers, from crystal receivers to synthesized ones, from single conversion receivers to dual conversion, and from 4ch to 8ch, there will be

Single Conversion Receiver
RS410II Receiver

CORONA never stops improving on the receivers flying range. The RS410II has improved the receiving range as far as 1.5Km (range tested on ground). Corona strive to reduce the size of the receivers, old technology components would need the receiver to be far bigger to match performance.

Longer remote control distance means more reliable control at normal ranges too. The reliability can even compare well with PCM receivers. PCM receivers have good reliability, that is because they use CRC code (cyclic redundancy checking) to replace the wrong data codes which may occur at the edge of signal range. The control will always seem to be fine normally, but when CRC code checking begins to replace bad data frames the PCM receiver wastes a lot of time to receive new data to replace the“bad data”(which happens at times at only half of the range described by manufacturer). So usually while we find that a PCM receiver has no glitches, its control response speed is less than of a PPM receiver in some conditions.

We make receivers more sensitive and with greater selectivity, and with Coronas DSP (Digital Signal Processing) it will make the reliability of a Corona receiver approach the leading PCM receivers. However, its control response speed will not be negatively influenced.
With a new improved circuit design, the RS410II advances IP3 (3rd Order Intercept Point) performance again. It compares closely with all famous brand RC receivers from around the world. IP3 performance of a receiver is vital for several R/C transmitters to be working at the same place at the same time. A receiver with low IP3 performance may still be working fine when 1-2 transmitters with adjacent channels are running in the same time, but once a third adjacent channel transmitter is working nearby the receiver will lose reliable control immediately.

Reliability, high performance and sale price, they are what CORONA can provide for you.
