FlySky RSSI Telemetry

December 7, 2021 Patrick Gilfeather

RSSI, which stands for received signal strength indication, was covered in the last post. The topic covered how the Nordic Seminconductor’s nRF240L0 wireless device could be used to measure RSSI values. Those values reveal the reliability of the radio controlled reception and interference that might be present. RSSI telemetry is basically a tool to see invisible radio waves that operate on the same operating frequency as the radio controller (TX) and receiver (RX). FlySky is a manufacturer based out of…

RSSI Interference

November 30, 2021 Patrick Gilfeather

Before diving right in on this topic, we should ask what is RSSI and why does interference matter. First off, RSSI stands for Received Signal Strength Indicator and it’s a measurement of the radio frequency power level present at the receiver (1 and 2). A radio frequency transmitter typically has a fixed power output level. As a receiver moves away or around the transmitter, the received power level varies. RSSI is a way to measure that variation. Typically the variation…

Modified Volantex Ranger 600 Controller

November 23, 2021 Patrick Gilfeather

The stock Volantex Ranger 600 TX is as basic as any TX can get. The undocumented throw reversals prompted a closer look at the controller. The terms controller and TX apply to the hand held radio controller used to operate the remote controlled plane, TX will be used going forward. One item that was replaced with a yellow LED was the beep indicator. Since a lot of bench testing was going to take place, the blinking LED would be less…
