This F@#$*ng Crossfire LQ thing again...

 I really don't know why this is so hard for some people to understand. Here's a quick explanation if you can't read manuals.

Crossfire

Operation Modes - There are two Op. Modes: Normal and Forced Telemetry.

Normal Mode:

  • Allows you to use 3 RF Profiles (see below)

Forced Telemetry Mode:

  • 50Hz and 4Hz update rates (switches between RFMode1 and RFMode0 based on signal quality). Basically, like the manual says, do not use it if you don't know what you're doing. I believe there's a bug...try it and you will understand. Good luck.

RF "Profiles"

  • Dynamic = Switches between RFMode 2 and RFMode 1 using unicorn magic.
  • Forced 150Hz = RFMode 2
  • Forced 50Hz = RFMode 1

RF "Modes"

  • RFMode 2 = 150Hz update rate. LQ Scaled [RTFM..300%]
  • RFMode 1 = 50Hz update rate. LQ Scaled [0..100%] <--not 100-200 ffs!
  • RFMode 0 = 4Hz update rate. LQ Scaled [0..100%] (only used if Forced Telemetry mode is set).

LQ prewaring at 70%, critical at 60%


Tracer

Tracer = RFMode 1 at 250Hz mode. LQ scaled [0..100%]

 LQ prewaring at 30%, critical at 20%. Now, if you are one of the few people that read manuals, you will notice why the TBS manuals need a bit of improvement. One place has the warning at 30% and another at 50%. Considering the issues people are having with random signal issues, I'd recommend starting with 50%. UPDATE: A later revision of the manual has 40% prewarning and 30% critical.

UPDATE 12/22/2021:

TBS is adding LoRa to Tracer. Initial tests look promising. That signal looks solid compared to "other" systems. RFMode 1 at 250Hz and RFMode 2 at 50Hz may break the OSD in INAV. Already thinking of a solution but TBS should change the modes to the corresponding numbers that align to legacy CRSF.

Now go and crash something.


Happy Halloween!

FrSky FPort Protocol New protocol came out from FrSky and Betaflight. The fix for uninverted-inverted drama. F3? F4? F7? Change a setting on Betaflight and done. In other news, I received a Kiss FC and four 24A Race ESCs today. I may get another set this weekend. (Stop it!)

 Why the FAA's Remote ID Rule is a Bad Idea The Federal Aviation Administration (FAA) recently published its final rule on remote identification (remote ID) of unmanned aircraft systems (UAS), commonly known as drones. The rule requires most drones operating in US airspace to broadcast their identity and location information, either through a built-in capability or an external module. The rule also limits the places where drones without remote ID can fly. The FAA claims that remote ID will enhance safety, security, and accountability of drone operations, and enable more complex and beneficial uses of drones in the future. However, many drone enthusiasts and industry experts disagree. They argue that remote ID will impose unnecessary costs, burdens, and restrictions on drone users, and infringe on their privacy and freedom. Some of the main criticisms of remote ID are: - It will create a barrier to entry for hobbyists and innovators who want to experiment with drones, as they will h...
