RD620 is the lightest (only 8.8g) 6-channel, full range, and ultra narrowband Dual Conversion receiver. Decoded by the onboard microprocessor, the resolution reaches 1024 in order to adapt to the digital servo and accurate servo. Like the DSP that all CORONA receiver uses, it rejects the glitch strictly. Compared with Single Conversion receiver, Dual Conversion receiver can reject mirror frequency more effectively if they have the same components and use the same DSP algorithm. Thus, it gets more reliability. For adjacent channel interrupt (with the transmitters of channe50, 51, 52, 53 working together, and not far way form them), RD620 can reject it more effectively. Inheriting CORONAs consistent style (small and light), both the size and weight of RD620 is the smallest. You can install it on Micro 3D CCPM helicopter or 3D fix-wing airplane in an easier way, and use it on small size, high speed and high-performance occasions. It can also be installed in the small size occasion, such as the indoor Micro Electric Aircraft, park fliers, etc. Of course, the full range and full performance of RD620 can be used in the occasion when long range is needed, such as the glider and large-scale glow plane. In addition, RD620 can deal with the busy flight situation, and guarantee the safety of the fly.
See the RD 620 User Guide for more details.

I have been looking for a good low cost receiver and have been using the Feigao's. But since trying the Corona's I have sold all my other receivers and replaced them with these.



I have tried it in my Fantrainer, a glithing making machine and I have had no troubles with it. Works better than my JR R610M receiver. Highly recommended

This is a brilliant receiver. I was using a Hitec Electron 6 in my small electric F3A, that was very prone to glitching. My Hitec 555 faired no better. I briefly used my Futaba FF7 PCM, but the Corona receiver is about 80% lighter, so I gave it a go. Despite not being PCM, its selectivity is incredibly good. NO GLITCHING! Hitec make excellent receivers, so for the Corona receiver to succeed where they failed tells you how good this receiver is. It's also VERY light. Most people seem to know it's good - United Hobbies struggles to keep enough of these in stock.
