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.

Good receiver. Not noise , I am testing approximately 400 meters because of my plane size.

( crystals step out from case receiver.)

If you have got jr tx and wan't to purchase this rx ,my suggestion is purchase a corona crytal too.jr crystal is not work very well.corona crystal works very well.

Ideal for small model.

Good receiver. Not noise , distance more 100 meters. But crystals step out from case receiver, can be get out from receiver or get caught by something.

Very light. Ideal for small and light model.

Excelent receiver, contrary to my GWS, Robbe and Futaba receivers I had zero problems. My real problem is that I have also the single conversion variants and they are equaly good. I fly only parkflyers (for now) so I don't push to the limits the receivers. And the most annoying thing is that UH don't offer for sale anymore the crystals for 40Mhz band (ch 50-54)europe. I hope this will change

great receiver

I use it on my DLG and works very very well: no glitch, no interfenrces.

It's my preferred receiving on my model.

I've used whit corona crystal and with hitec crystal, both dual conversion.
