RD820 es el más ligero (sólo 9,5 g) de 8 canales, toda la gama, y ​​el receptor de conversión doble de ultra banda estrecha. Decodificado por el microprocesador a bordo, la resolución alcanza 1024 con el fin de adaptarse a la banda muerta más tensa de la servo digital y servo precisa (por lo general 1 es solamente). En comparación con el receptor de conversión individual, un receptor de doble conversión puede rechazar la frecuencia de espejo con mayor eficacia si tienen los mismos componentes y utilizar el mismo algoritmo DSP. Por lo tanto, se vuelve más fiabilidad. Para interrupción del canal adyacente (con los transmisores de channe50, 51, 52, 53 trabajan juntos, y no muy lejos manera formarlos), RD680 puede rechazar de manera más eficaz. De acuerdo a la comprensión de la industria de la electrónica moderna de la Corona, el tamaño y el peso del RD820 son los más pequeños. El diseño especial de la gama completa y el rendimiento puede dejar que se instala en la mayoría de los helicópteros 3D CCPM, avión de ala solución 3D y aviador del parque con facilidad, así como el planeador, el plano resplandor a gran escala. Además, RD820 puede hacer frente a la situación de vuelo ocupado, y garantizar la seguridad de la marcha.

Have two of these, used on different channels (63 & 74)and have used them at a field where single conversion receivers regularly glitch, with no issues after about 20 flights. Rating would be 5 star except for Xtal location effectively increasing size of Rx and apparently poor Xtal availabilty.

I bought two of these receivers togheter with crystals and had one set sent to Thomas Scherrer for testing. He found two potential issues with it:



1) A transmitter on any channel (61-80) can cause blocking if it is really close (less than 5m).



2) Although it is a dual conversion receiver, it has receives also on a mirror frequency of 38.1 MHz (if using 35.1 MHz crystal).



For further details, see:

Thomas has also tested a lot of other receivers. The results are available on-line at:

Magnfico receptor, muy ligero y fiable 100%.

Lo recomiendo en veleros con motor elctrico. Nunca he tenido interferencias con la electrnica (motor-variador-batera) ni prdida de seal a distancias considerables (300-400 mts.)

This is a great receiver! Too bad they dont have it in stock more often! The only

weakness is that the antenna exit is sharp

and will destroy the antenna unless you attend to it.

Version in 35 MHz wurde samt original Quarz geordert. Empfnger arbeitet einwandfrei und ist fr einen 8 Kanal Doppelsuper uerst klein!

I have bought and tested three new RD820II receivers and I am happy to say that minor problems with channel 1 output are gone (see my review for RD820 above). I have tested several ESCs without any problem - JETI SPIN, JETI JES, HXT 18 and 36, Towerpro 18.
