Among Corona receivers, from crystal receivers to synthesized ones,
from single conversion receivers to dual conversion ones, from 4ch
to 8ch, there must be one type suit for you.
Single Conversion Receiver
RS810II Receiver
CORONA never stops improving the receiving range. RS810II has
improved the receiving range as far as 1.5Km (checking range on
ground). If we use traditional technology, how big the receiver
should be made to reach such a far receiving range?
Further remote control distance means more reliable control. Even the
reliability can compare beauty with PCM receiver. PCM receiver
has good reliability because it uses CRC code to fill up the wrong
codes which leading by shortage of receiving range. The signal will
always seem to be fine ostensibly, but CRC code of PCM began to
fill up “bad data cavity” which happens at times while exceeding
half of the distance described by manufacturer. PCM code wastes
a lot of time to receive more data to fill up the cavity of “bad
data”. So usually we feel that PCM receiver has no glitch, while its
response speed is less than PPM receiver.
We make control distance be further so that receiver can locate in
stable RF Electromagnetic Field, it will make the reliability of
Corona receiver approach to PCM receiver. Meanwhile, its
response speed will not be influenced.
With improved circuit design, RS810II advances IP3 performance
apparently, and it can even compare beauty with all famous brand
receivers around the world. IP3 performance of a receiver is vital
for serried R/C transmitters working at the same place. A receiver
with lower IP3 will still working fine when 1-2 transmitter with
adjacent channel working in the same time, but once open the
third adjacent channel transmitter, the receiver will lose control
immediately if it has poor IP3 performance.
The light weight and small size of RS810II predominate in other
receivers. Furthermore, we have moved the crystals of RS810II to
side face, which really improves the reliability of replacing crystals.
We have also improved DSP. It can make more strictly filter about
received signals and eliminate glitch efficiently.
You can put RS810II receiver in any place when you install it on
whatever electric puddle-plane, 3D plane, glider or training plane.
And don't worry the trouble which will be brought by changing CG.
RS810II receiver has the structure of level inserted pin by special
design and assorted with super thin electronic parts. The thickness
of RS810II receiver is only 7.2mm which make the installation
more convenient.
Reliability, high performance and sale price, they are what CORONA can
provide for you.
