RD820是最轻(仅9.5克)8通道,品种齐全,超窄带双转换接收器。由板载微处理器解码,分辨率以适应数字伺服和准确伺服的最严格的死区(通常只1是)达到1024。用单次转换接收机相比,二次变频接收机可以更有效地拒绝镜像频率,如果它们具有相同的组件,并使用相同的DSP算法。因此,它得到更高的可靠性。对于相邻信道中断(与channe50,51,52,53的发射器一起工作,相信在不远的方式形成它们),RD680可以更有效地拒绝它。根据理解科罗纳的现代电子工业,RD820的尺寸和重量是最小的。品种齐全,充分表现了特殊设计,可以让你在大多数3D CCPM直升机,3D修复翼飞机,和公园传单的安装很容易,还有滑翔机,大型平面发光。此外,RD820可以应付繁忙的飞行情况,并保证飞行的安全。

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.

I just bought 3 of this receiver. Absoluty no problems and full range.

I will like to buy more of them!!
