DATA RADIO FREQUENCY CONSIDERATION
1. FeiYu Tech provides two options for Data Radio
frequency:

FY606 – 2.4 GHz, Full Duplex

FY602 – 433 MHz, Half Duplex
2. When considering which Data Radio to choose,
consider the following factors:
a) Frequency interference – select a Data Radio
that will least effect your existing radio system
(Video and RC Transmitter).
b) Speed of Data Transfer – Full Duplex (FY606) will transfer data at a faster rate compared
to half Duplex (FY602). This is important especially when you are using the Data Radio to
manually control your aircraft. The FY606 has a higher data transfer rate (15 to 30 Hz)
compared to FY602 (10 to15 Hz) resulting in less flight control delays.
c) Transmission Range: The FY602 (433 MHz) has a far longer range compared to the FY606
(2.4 Ghz). The FY606 has a tested range of 4 kilometers.
3. The FY system allows you to utilize your own third party data modem. However, please be
careful not to use Data Radio with too high data transfer frequency. The higher the transfer rate,
the more stress on the data communication channel. 2Hz is the preferable refresh rate. (To
change the frequency:- go to ―Communication‖ – ―Telemetry data‖ and select the appropriate
refresh rate).
4. If the outgoing transmission has very high data transfer frequency, as there is a possibility that
the incoming 10Hz telemetry data (longitude, latitude, altitude, airspeed, heading course,
position, flight status, etc.) from your plane to your ground station can be blocked.
5. We advise you choose 2 - 4Hz for Telemetry and 15 - 30Hz for Remote Control when using the
FY606 to avoid two-way signal blockage. Whereas for the half-duplex FY602, choose 1 - 2Hz
for Telemetry and 10 - 15Hz for Remote Control.
6. Because of communication ‗stress‘, too high data transfer rates will also reduce the Data Radio flight range.
