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 use it for a long time in an helicraft Trex-450 Xl without no problem. Only antena must be manipulate with care. A good product at the right priceHeads up JR users!
I tried this receiver on both a JR 6102 and 7202 transmitter, using a Castle Thunderbird 18 ESC. IT WILL NOT ARM THE CC ESC using these particular transmitters. I've read of others experiencing the same problem while using JR and Castle ESC.
The Corona 4 ch single conversion rx does not have any problem with these transmitters or ESC.
Perhaps a Hextronik or TowerPro ESC would work with it? Anybody tried it?Does not work with 9c and Spectra ModuleI have 4 of these and have not had any problems what so ever. The best receiver for the price and you cant beat free shipping.

What more could you ask for.
What a steal and light too. These props emulate the Accipius Baddus props which I have experience with and these Hy props are the same type. Wish they had a better size assortment to pick from as I would use on other planes.I bought one of these from elsewhere at bug premium. Works great.
I am just waiting for the 8-ch to get back in stock so I can order one of each together.
I've done some basic testing so far and it has worked perfect without any glitching. I wasn't able to find any crystals on UH, so I used a RX crystal I already head for a Hitec RX, worked perfectly. I think we have a winner with this RX.I currently have one of these 6 channel RXs in an E-Flight J-3 Cub and it has been a supurb value. It is also 6 channel so I did not need a Y harness for the 2 aileron servos. I am very happy with this RX all around. I am not receiving any glitching and am able to fly out full range with this RX. Compared to the higher priced "name brand" RX's this is a great RX in a small package that packs a BIG Value.

Nice resiever,need more! Recommend
Thanks UH !I have two so far, faultless performance in electric glider at long range. Will purchase more.
