R9 is FrSky’s long range RC system and has been initially released in late 2017 as competitor to TBS’ Crossfire (CRSF) system. The R9 system has now seen quite some iterations and seems to work fairly well, especially with the latest FLEX firmware.
FLEX is short for flexible - because it easily allows you to adjust the frequency you are transmitting on without the need to flash different firmware per region.
With a properly set up R9 system you can easily have a control link over a couple kilometers.
ACCESS (Advanced Communication Control Elevated Spread Spectrum) is FrSky’s newest air protocol. Air protocols are used to transmit data over the air from transmitter to receiver. The air protocol is also sometimes referred to as transmitter protocol.
You will most probably have heard of D8 and D16, those were FrSky’s transmitter protocols up until now and ACCESS is the successor of D16 (D16 is actually the short name and the proper name is ACCST) - maybe ACCESS will soon be known as D24.
In this article you will learn how to set up your receiver with your flight-controller. Setting up your receiver consist of physically attaching the receiver to the flight-controller and software setup within Betaflight.
There are different protocols enabling receivers to communicate with the flight-controller. Some only work in one direction, others work bi-directional, so that the flight controller can send data back to the receiver and the receiver on the other hand can transmit this data back to the transmitter.
The Caddx Turtle V2 is a very popular micro HD, FPV camera. Most of the cine whoops like the Cinebee, Mobula7 HD or the Bushido are equipped with this camera.
Unfortunately the default settings are in my opinion not the best. Luckily you can change quit a bit when you have the control board for the Caddx Turtle. Not all of the models do include this control board. And before you get tempted: the Runcam control boards will unfortunately not work.
DaVinci Resolve is very picky when it comes to container formats, video and audio codecs - especially in the Linux version. The first step after reviewing my FPV footage (and deleting what I will definitely not use) is converting it into a format that resolve can handle.
My main cameras are a GoPro Session 5 on my five inch rigs and a Caddx Turtle V2 on all smaller rigs and my brushless HD whoops. But this guide will basically work with any source material you have problems opening in DaVinci Resolve.
As you might know, I am personally a big fan of the Taranis X-Lite - I don’t like the big clunky breadbox transmitters. I initially started out with a Turnigy evolution and then transitioned to the Taranis X-Lite simply because I wanted to use the OpenTX firmware.
The Taranis X-Lite comes with an expansion bay on the back. This is not the typical JR module bay that you might know from other transmitters like the Taranis X9D - instead it is a smaller version, custom to the X-Lite.
Nonetheless, there is still a couple of different external RF modules available for the smaller port of the X-Lite.
