Long range radio systems using 900MHz including the Frsky R9M and TBS Crossfire typically use a single dipole antenna on the receiver. The optimal antenna positioning can be different from traditional 2.4GHz systems with diversity monopole antennas on the receivers.
F1, F3, F4 and F7 are the different processors in flight controllers. This article explains the differences between these MCU, the advantages and disadvantages and help you decide which FC suits you best.
This tutorial explains how to setup the R9M TX module and R9 Mini receiver in Betaflight. The R9M is a long range module that operates on 900MHz band. It’s compatible with most Frsky’s radios including the Taranis X9D-Plus, QX7 and Horus X10.
This tutorial explains the different flight modes in Betaflight and how to setup Betaflight modes. The process should be similar regardless the quadcopter, flight controller or radio you use.
In order to activate flight modes and features in Betaflight you need to setup the switches in your radio first. I will show you how to do it in OpenTX which is the same system used in the Frsky Taranis X9D, QX7, Horus X10, X-Lite, and Flysky Nirvana.
