"Thanks for this, reminded me to balance my props/motors. Waay better now. Still a bit noisy at vcc, but helped a lot. So first of all, (re)balance. : ) Rod Davis said:

"M bad. Log is opens. : ) Rod Davis said:
That's odd. I just looked at the log and the FMT messages are there. The log file was generated on 3.4-rc2. I'm just using one of the modified TH9Xs 3DR shipped with the Iris+."

"@Rod: when i open the logs provided, it says there is no FMT messages. What kind of radio are you using?

"Ordered an ACSP5, hope that fixes my problem.
Im connecting servos, vtx, etc using dedicated regulators, no vcc to pixracer from there.

"Just after writing about my setup, i started to think about i may have board power issue.
