RD820 is the lightest (only 9.5g) 8-channel, full range, and ultra narrowband Dual Conversion receiver. Decoded by the onboard microprocessor, the resolution reaches 1024 in order to adapt to the tightest dead band of the digital servo and accurate servo (usually 1s only). Compared with Single Conversion receiver, Dual Conversion receiver can reject the 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), RD680 can reject it more effectively. According to the understanding the modern electronic industry of CORONA, the size and weight of RD820 are the smallest. Special design of the full range and full performance can let you install it on most of the 3D CCPM helicopters, 3D fix-wing plane, and park flyer easily, as well as the glider, the large-scale glow plane. In addition, RD820 can deal with the busy flight situation, and guarantee the safety of the fly.
See the RD 680 User Guide for more details.

Haven't flown with this yet, but it seems like a nice unit. Outstanding price. My Futaba crystal works in it on the bench. But I still have to range check it, too cold here in Canada to do it now.

I have one of these from some other vendor and it works great. United sells them very much cheaper too.

I've used two of these receivers in crowded flying fields glitch free. I presently trust one to an expensive molded scale Salto (full house sailplane) with complete confidance. An Excellent Value!

Compre este recividor y lo monte en un avion y e tenido problemas de interferencias cuando vuelo con otras personas. Le e cambiado los cristales y sigue haciendo lo mismo.



No puedo volar con otras personas con este recividor ya que las interferencias son constante. Cambie el recividor por un futaba y no tube mas problemas.
