    Bumped Gyro and PID back to 2000. Hover test is fine. Getting some drifting so can’t get a tail tune. But at least I got the heat out. Would be nice to see some BB logs to see what is different between 0.5 and 0.6. 🙂 I can do more limited LOS / tailtune stuff in my limited back yard. Haven’t tried FPV in my limited space and not enough daylight to head out to the field.

    Cheers!

    FYI, I have my FC hard mounted. I may throw some rubber bobbins on it.

    Definitely seems smooth in my tiny plot flying LOS. Can’t seem to get the drift out of it to get a tailtune. Going to put it away for now and work on one of my quads.

    Thanks for testing!

    It seems that next thing is to fix the blackbox.

    I don’t have high confidence in Cleanflight anymore, check this issue: https://github.com/cleanflight/cleanflight/issues/2494.

    Seems like Cleanflight is not so clean anymore. I wonder if Dominic tested the release at all.

    I’m seriously thinking of converting over to Betaflight.

    @lauka,
    Interesting… I was doing all my LOS testing in angle mode. I can see how the extra vibes from higher pitched props could get amplified by that. Not sure how much work it would be for you to code, but I’d be willing to test BetaFlight based TriFlight. I have a Trifecta that could be thrown back together to have multiple platforms and FCs for testing too. I’ve been thinking about setting up a dev environment. Haven’t coded much in 20ish years, but could still use it to poke around and compile test versions.

    Cheers!

    Managed to attempt an in-flight tailtune out at the field. Failed with double beep. Tried a second time, but could not get the drift out again…. Flew 1 pack FPV with the same settings I posted up yesterday. Kinda twitchy, Waggly, and not as smooth as it’s been with 0.5. (possibly due to no in-flight tail tune)

    Cheers!

    litterbug I had to balance my props on the baby they were way out of balance which led to significant vibrations. This might be the cause of your tune failure, not sure. If you haven’t balanced them give it a shot.

    Usually these tiny copter props come prebalanced, but the ones that came with my baby kit were out by a mile. Perhaps yours are too.

    @billyd,
    If I switch back to TriFlight 0.5, tailtune works fine, even with the higher pitched props. There is something about the way the 0.6 alpha version works that seems to amplify rather than filter noise. On 0.6 RC2-prerelease, changing from 5050 tri-blades to 5045 tri-blade props made the difference between cooking hot motors in 30 seconds and nearly unflyable, to cool running motors running for 4-5 minutes of somewhat aggressive flying. Both sets of props run cool and have completed tail tunes on 0.5. Both sets are brand new, run true, and appear balanced on my stand.

    Unfortunately the weather has taken a turn for the worse. Was sunny and 78F Friday, and Saturday was 32F, Rainy, Snowy, windy, and very gusty. Doesn’t look much better today. Not sure when I’ll be able to get out next.

    Cheers!

    I think we just need to wait for the fixes to Cleanflight.

    I started looking into the Betaflight rebase but it’s too much work for me ATM, without the parameter groups in Betaflight.

    @lauka,
    No worries. Going to try soft mounting my FC with some rubber bobbins and see what affect that has. I’ve been running them on all my more recent builds.

    Cheers!

    I mentioned this earlier in the thread that some of the parameters governing gyro lpf and other filtering appear to have changed from .5 to .6. Lauka had asked me to list them but I haven’t been able to get to it and I am not near my shop to check.

    Basically if you flash with .6 and try to copy paste a dump from .5 you will see errors for the values that are not accepted if you scroll through cli after you paste the dump. Some of the constant names have changed so the values are not accepted, and other values are different than in .5 for those changed constants.

    @billyd, I started from “default” and only changed what was needed for the Radio and flight modes. I later added the recommended settings for the baby tri. I don’t like copying cross-version when testing. Usually try to start with as close to default as possible and then add stuff back in and make adjustments. I noticed quite a few changes when I compared default values between releases.

    Parameters with new default values

    set gyro_sync was "ON" now "1"
    set gyro_lpf was "188HZ"  now "OFF"
    set d_level was "100" now "75"
    set tri_dynamic_yaw_minthrottle  was "235" now "500"
    set tri_dynamic_yaw_maxthrottle was "50" now "12"
    

    Managed to get the FC soft mounted today. Weather bad still, so no chance to get out. Gave me time to tweak my FPV/OSD setup a bit. Was slightly out of focus, clipping bright areas of the image, and my power field positions were reversed.

    Cheers!

    Thanks litterbug. I wonder if any of those new parameters are causing any issues…..

    If you fly in angle or horizon mode, Cleanflight 1.14 or 1.14.1 should be avoided at the moment, or any software based on it. The mistakes that have been made with sampling and filtering the accelerometer data mean that there is huge aliasing noise induced into the readings.

    I was helping out a user with altitude hold problems on 1.14 over on RCG and looking at his black box logs showed that the accelerometer data was varying as much as +/- 4g within the space of 0.12 seconds.

    That’s a physical impossibility!

    Cleanflight 1.14 is broken.

    @lauka , I see there was a 1.14.2-RC1 released on the 6th. Does this fix any of the issues we have been waiting on?

    Changes since v1.14.1:

    Improve accelerometer filtering.
    Fix RSSI reading on OSD.
    Add support for SPRacingF3NEO FC/PDB/OSD/VTX FPV Stacking System
    Other minor bug fixes.

    Cheers!
