    My motors are make glitching sound randomly. Anyone know why?

    Just upgraded the board from Naze32 to F3FC. Didn’t have this problem with the Naze32. Thought it might be related to the tail servo, replaced it AND the tail motor ESC and I’m still getting the glitching. I tore this thing apart and resoldered all connections. No luck.

    My setup:

    •FrSky Taranis x9d plus Tx
    •FrSky X4RSB Rx
    •all RCE parts (motors, ESCs etc)

    What the heck? That sounds awful! Like a loud ticking.
    What firmware are you running? Can you try flashing the 0.5 final https://github.com/lkaino/Triflight/releases/download/0.5/triflight_0_5_F3FC.hex

    Doesn’t look like you have anything else attached to the F3FC?

    Are those the Aikon or LittleBee’s ESC’s?

    I’ve experienced a similar weird noise on the RS2205-2300 and DYS XM20A after using these ESCs for developing and debugging new cool feature for CleanFlight Configurator.
    Flashing them back to BLHeli 14.6 solved the issue, probably just resetting all the settings back to defaults may help too. Do you have ONESHOT feature enabled on the FC?

    Thanks for the input David and hertz.

    I’m running the Little Bee 30A ESCs that I purchased from the RCE shop. ONESHOT is enabled in the FC. I am running the latest Triflight version (I have also tried an earlier version with no luck). You are correct David, nothing else is attached to the F3FC.

    Very perplexed right now…

    I should also add that I tried resetting all the settings in CleanFlight back to defaults (started with a clean flash), which resulted in no change… still getting the glitching.

    Need to get a camera in the air this weekend…

    Update:

    • rebuilt tail boom with all new parts (servo, motor, ESC and wiring)
    • checked all connections on the board
    • replaced the reciever

    STILL GLITCHES

    Just noticed errors at the bottom of the Cleanflight interface (not sure if they’re related to the glitching though), see screenshot.

    How does the VBAT reading look in cleanflight? Is it stable or does it jump around? Saw in the forum thread that it’s reading 2.6V?
    Can you do a screen record of the sensor tab while the glitching occurs? Interested in how the sensor and motor output lines look.

    Very strange problem indeed. Not 100% sure what it is yet

    VBAT seems pretty consistent in Cleanflight, however there were minor fluctuations observed. Link to VBAT, sensors tab and motors videos below.

    During the recordings I held in air to avoid wobbling caused by tail servo.

    Interesting to see barometer graph change so much since I was holding it at approx the same place in the air.

    Wow that is horrible. I’m pretty sure it’s the 3.3V regulator that’s not outputting a stable voltage
