Note that there is a stick filtering (6-sample averaging) that exists in OpenTX, which introduces a varying delay. To properly measure latency a custom version of OpenTX was built to get rid of this filtering. Crossfire Micro TX module with Crossfire Micro V2 receiverįurther Reading: Does the Frsky X-Lite support Crossfire?.R9M-Lite TX module with R9 Mini receiver.The latency are measured with the TX modules installed in the Frsky X-Lite. Measuring Latency in R9M-Lite and Crossfire The latency is measured between the points before OpenTX and after RX (bold text). Gimbals => TX Interface (OpenTX) => TX module => RX => FC The latency in our RC link can be divided into 4 parts: Check out our review of the Crossfire vs. You can learn more about the TBS Crossfire in this article. The latency test was done by Andrey Mironov, with his permission to share the result here. Here is a screenshot of the Model Setup in OpenTX. Using the correct frequency for your region is critical to signal reliability. You might want to get a 45 degree or even a right-angle RP-SMA adapter.įlash the correct firmware on your radio and RF module (and receiver), and select the correct mode for your region. The way we hold the transmitter will have the antenna pointing directly at the aircraft which gives a weak signal. You need to mount them in a specific way to have the best possible signal. Radio receiver options are also pretty good, the R9-mini and R9MM receivers are even smaller than the 2.4GHz R-XSR, even better at half the price! But just like any 900MHz systems, antenna mounting is different than 2.4GHz. You might even be able to go behind obstacles you could never dream of with 2.4GHz. You can fly around big fields and not have to worry about losing signal. It’s easy to install on the X-lite without doing any mods, basically just plug and play! The X-Lite actually support Crossfire too but it requires special mounts.ĩ00MHz radio system provides a much more solid and reliable link compared to the built-in 2.4GHz RF module in the X-Lite. The R9M-Lite is an affordable long range option compared to the Crossfire. We previously reviewed the R9M module, which is for the radios with JR module bay such as the Taranis X9D-Plus, Q X7 and Horus X10S. The R9M-Lite module is the miniature version which is designed specifically for the Taranis X-Lite radio.
