Hey everyone,
I’m hoping someone here might be able to help me troubleshoot an issue I’m having. I recently picked up a Cinelog 20 BNF and am running it with DJI Goggles 2 and the DJI Remote Controller 2. Everything was working fine out of the box, but after my very first crash, I started running into problems.
Now, when I try to rebind and rearm the drone, I get a "Remote Control Stick Error" message in the OSD of the DJI FPV Goggles 2. I tried reflashing the flight controller via Betaflight (Comand line with geprc's manufacture profile), but now the board no longer recognizes any stick inputs from my controller when the drone is connected to Betaflight and powered with a battery (throttle stick is all the way down and googles are set to sbus fast).
The DJI O3 Air Unit is still transmitting video just fine, so I don’t think that’s the issue.
Has anyone run into this before? Is there anything else I can try to fix this? Or does it sound like I may have to replace the flight controller?
Any advice would be greatly appreciated!
Thanks in advance!

I haven't used a DJI controller before but if its like Expresslrs you might have the rx set to the wrong Uart. So maybe try setting the rx to uart 1?
If you still have video but zero stick input and see “Remote Control Stick Error”, this is almost always a broken or disconnected SBUS signal between the O3 and the flight controller.
The crash likely loosened a plug, broke a wire, or cracked the SBUS pad on the FC. Reflashing Betaflight won’t fix that.
If the Receiver tab shows no movement at all while powered by a battery, it’s not a settings or binding issue.
Check the O3 to FC cable and the SBUS pad first. If that connection is damaged or the SBUS input on the FC is dead, the fix is either rewiring to another RX pad or replacing the flight controller.
