I'm running Dshot1200 at the moment on 3.1.7, I have been flashing the nightly build to tweak the wraiths with the new blhelisuite 32, then flashing back to 3.1.7 to fly. Current and voltage worked with some calibration. Voltage was spot on from the factory, but the current sensor was way off. I do have one Bf f3 board on another build that's having trouble with current reading, but I'm not super worried about it, as voltage has been my main fly by, and the current was really only used to make sure my esc's we're sized up enough to not burst into flames.

Have you tried a full erase and flash on the board?

Yes, at the beginning I did a full erase when I updated the firmware. My problem is that each time I select "Onboard Voltage" and fill out the fields and Save and Reboot, then it comes back up as those fields being empty again. Like I never set it up.

My Betaflight software doesn't go to Dshot1200. Maybe because I am using the Chrome Extension and not the full program..

Hmmm that funky you may want to ping the vendor and let them know that sound like something up with the board if it's not working after a full erase.

To set dshot1200 you need to go into cli and set it manually. 3.1.7 supports it just not from the drop down menu. I can't recall the exact command but typing in set pwm will pull a list and you'll see what it's currently set to and can change it there pretty easy.

Thanks for the feedback. Unless there is a compelling reason to go to dshot 1200, I'm enjoying dshot 600 for now. Happy Flying.

I set it there as soon as the got the wraiths so I can't say if there's a difference, but 1200 sure is smooth while still being very responsive if that's possible.
You won't be disappointed by these esc's I have them on 3 ( soon to be 4) quads and love them on each build.
