RC12_OPTION is set to 94.

The RC channel moves as expected in the Radio Calibration page under Setup.

However when I press the buttons bound to RC12, the quad does not behave as expected. The VTX power does not change from 0mW. Arming doesn’t seem to make a difference. Is it being controlled by some dynamic RSSI control I don’t know about? The VTX in question is an HDZero Race V3. It is updated to the latest firmware.

We don’t have support for MSP VTX power which is what HDZero supports. You would have to wire up SmartAudio and do it that way.

Thank you for the reply. I think I must have been confused. I thought “DisplayPort” was a protocol in and of itself. But I need “DisplayPort” and MSP both, if I understand you and the following image correctly:

So if I’m out of UARTs, my only option is going to be to use stick commands.

Right and SmartAudio is not really recommended for HDZero. I’ve added MSP VTX to my list but might take me a while.
