RD820 Dual Conv. 8CH Receiver

Nov 14, 2007

I have tested these recievers against my Hitec and other recievers and found them to be more sensitive with a total lack of glitches. Our flying site has two distinct interference areas, these recievers seem to be imune to the glitches most other brands suffer in these areas.



Tested with Hitec Spektrum 7 Tx with the antena down.



Hitec reciever RCD3500. Started to glitch at 11 metres no responce at 17 metres.



RD820 Still stable and glitch free at 40 metres



I spend months building WW1 fighters I will be trusting them to RD820 recievers from now on.



I am using Hitec Dual conversion Crystals with these recievers.

RD820 walk test

Nov 14, 2007

A range check using a Hitec Optic 6 Tx (fully charged)with antenna down and Hitec dual conversion 36.430 Xtals holding one foamy in each hand and walking away from Tx gave the following results:



Corona RD820-36

First servo glitch @ 39M

First Motor glitch @ 45M

Total chaos @ 56M



Hitec Micro 555

First servo glitch @ 12M

First motor glitch @ 15M

Total chaos @ 20M



In the air the Corona has been the first Rx I have used that has been totally glich free (12 flights so far)

Only downside is the Xtal I used is not a tight fit in the socket, perhaps other brands are different.

Draw your own conclusion but I'm putting my other (much more expensive) Rx's on ebay

Great micro rx. The best micro I've tried. out performs my jete rex ,futaba ,610 jr and feigo. totaly glitch free and with full range. Had to use a futaba dual conversion rock as my hitec didn't work( maybe a dud rock)Can't wait for them to come back in stock. I need more!
