Triflight 0.7 Beta 3

[fomoco_44]

@ Lauka

Just wanted to check that the default PID’s in Beta3 release are for the stock BabyTri?
I have just flashed it onto my stock MiniTri F3 and it flies really well, better than it ever has, and so now I am focusing on getting a good tune.
Do you have any hints/tips on PID tuning for Tricopters?….I know the theory behind tuning for quads, which I can do ok, but I’m not sure if there are any ‘Golden Rules’ to follow with Tri’s….i.e high yaw Pterm inducing roll oscillations or vice-versa, pitch Pterm on a front-roll as opposed to a back-roll, can you just lower I & D on each axis and turn up P until it oscillates(same as a quad) etc etc?

Great job on the code!!

Mboarman, the tilt to the right shen arming is not a problem. You should be able to take it into a stable hover now. I guess the firmware is setting the tilt angle to an approximate value required to compensate the torque imbalance coming from the rear motor. In hover you will see you that the motor is tilted at an angle.

Appreciate the insight, coming from the world of quads, it just seemed off that the motor has that much tilt in ‘neutral’. I expected it to be in the straight up vertical position. Time to lift it up.

Have fun!

@mboarman

The Tail Servo tilting over is how it counteracts the torque from the other two motors. So your video looks normal to me.

Been away for awhile and my memory is rusty and alot has changed.

Uploaded the beta3 firmware for rcexplorerf3 and running latest version of cleanflight. I am unable to set current meter or any power options. Says I need a firmware upgrade. Says battery amperage voltage settings not supported with API<1.33

Do I have to run an older version of cleanflight? Sorry I’m probably doing something stupid.

Hi BillyD, we’re on Betaflight now. That version uses betaflight 3.1.7.

Hope this helps!

[billyd]

Thanks. I can’t find 3.1.7 I can only find 3.1.3 or 3.2.x and above on the release pages of betaflight.

USING THE BETAFLIGHT CONFIGURATOR version 3.2.2:

When you install from this source: https://github.com/lkaino/Triflight/releases for your specific board, and type “version” in the CLI, it will identify it self as version 3.1.7, because it is based on Betalflight 3.1.7.

When you install from this source (untested version): https://rcexplorer.se/forums/topic/testing-triflight-rebased-on-3-2-2-betaflight/#post-40318 and type “version” in the CLI, it will identify it self as version 3.2.2, because it is based on Betalflight 3.2.2.

Thanks guys I use this open source stuff once a year at most and every time I do an upgrade I have to relearn everything lol.

Now I have to go re-learn BLHELI suite for the 5th time lol

[Terje]

Give the BLHeli configurator plugin for Chrome a try 🙂

**Here’s my recent Diff and Openlog from Triflight 0.7 Beta 3**

Please note that this was a very short flight to test the logging rate and that Notch-Filters 1 & 2 have been disabled. (Motors are not even running warm)

Ahh the log-file i tried to upload is too big. Here is a link to my Google-Drive: https://drive.google.com/file/d/1c5gg9JSo5LPAPguB615yj75mLekJLbsn/view?usp=sharing

[billyd]

Ok betaflight configurator 3.2.1 is no longer available on github just the source code.

[LitterBug]

Need to knock the dust off the Baby Tris and give this a spin.

Cheers!
