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 1ìs 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.

Test sur Hotpoint 40, 1,50m envergure.

Trs longue porte, test antenne replie et emetteut ras du sol, avion la verticale peine visible et aucun problme de porte.

Trs bon produit pour un prix trs bas. Bravo UH.

Very small receiver, good connections for the servos. This receiver has a long range and no interference even with an electric brushed motor (I had some interferences in the past with a branded single conversion receiver).



It is a pity that there is no quartz available in 41 MHZ for this receiver.
