@Lauka: Am I right to install the triflight_0_5_F3FC.hex from
https://github.com/lkaino/Triflight/releases ?

comparing the preconfigured PIDs to the old ones delivered with the older alpha version they are much different. would it be clever to manual copy the old ones to the new triflight? is the firmware writen for the big tricopter? But the values aren’t the one dave gave out vor V4…
or where comes the difference in the PIDs?

Sooner or later I want to learn how to PID tune a copter, but I hoped it would be later^^

Just guessing, but have you tuned the servo on the bench before? Like Dave shows in his video of setting up the electronics? While I was trying to get everything running I went over and over again with flashing the board to start on a clean setup and forgot the tuning of the Servo once or twice.
Don’t know if tailtune refuses to tune in flight if the servo hasn’t been tuned before.

@norwenkel: good to know that these errors are usual. Is there a list or documentation about the errors? didn’t find much usefull on the web.

Good to know I can do something for more serial devices…
When the first flight are satisfying and I get some practise I will think about what to upgrade. But this is maybe worth another thread (if there isn’t already one) or i will do some research in the forum(s) and youtube.
OSD sounds good to me, the rest is for now too much for me.
Thanks for the input!

@Lauka first of all thanks for the effort you put into triflight! And thanks for mentioning there is a new version. I just downloaded the hexfile from the page of the Mini Tri in the shop.
Maybe Dave can update this link?

Now i got back at the bench.
what i did so far:

_____________
taranis

companion 2.0.20
opentx _x9DP-mode2_EU (2.1.6 variant217)
factory reset (eeprom erase)

_____________
internal XJT
flash internal module
XJT_eu_150413

_____________
X4R
flash external module
X4R-X4RSB-CPPM-EU Version 150624 (on frsky-rc.com it is listed as Version 150729)

bind with taranis while CH2+3 are jumpered (in D16 with channels 1-16)

_____________
Cleanflight
Configurator 1.2.3
firmware: triflight_0_5_ALPHA2_servo_release_RCE
full chip erase
baud manual to 256000
-> usb device successfully closed (after flashing)

now in cleanflight- connected it shows 0 packet errors and I2C errors: 3

connecting via sbus
make all adjustments like JRach (scroll up in this thread) and David (his video how to set up electronics)
– setting up ports
– configuration like JRach wrote down
– leaving PID alone
– adjusting the taranis on the correct microsettings
– mapping the channels in the right order (forgot that on first try- copter wont arm because throttle isnt at zero ;))
– setting up all modes and switches
– calibrating servo
– calibrating accelerometer
– calibrating escs

and now: TADAAA!!! it works!
JIPIEH!!!

I will try it out rommorow- hopefully the weather is nice to me.
Thanks to you all giving me hints and tips!

What does the I2C error:3 mean?

[horstrainer]

@Norwenkel Yes I use triflight 0.5.
I will start from zero with:
-board(with manual baud rate)
-TX (EU-OpenTX)
-RX (EU- LBT- will try cppm and S-bus).
-I will check (again 😉 all cables and the whole setup
-with and without telemetry

If that doesn’t help i could try the non EU version for rx and tx, but i doubt, that this makes a big diffenrence.
I will report the outcome.

Where do i get/see the i2C or packet errors? (didn’t find much helpfull with a (very) short google research)

@ GAntonjo: Thanks for the clarification. I just thought the hint on “no CPPM” could identify which firmware i used, but I will try both ways- maybe that helps.
To the Question of “my way of flying”? Right now i don’t have a way of flying because i am just learning. I had 2-3 Lipos of LOS flying when evrerything coincidently worked- FPV is the next step.

@ Terje: black (brown), red and yellow cables connect the CH4 with UART1 (GND, +, RX)like the picture of the F3FC board shows. Telemetry was tried, but for Troubleshooting I de-activated it and deconnected the s-port cable (don’t know the colour because I don’t have it in front of me right now) on the TX pin of UART2.

Right now i don’t care about other ports that i need for OSD or Blackbox or whatever. I just want to fly FPV and get it running. So I will test everything again- hopefully tonight.

Thanks for the help so far! It’s a great community! I am very happy to have asked here in the forum.

Hello GAntonjo,
Do I understand you correct? You suggest to use cppm?
After reading a bit on oscar’s site
I thought its better to use sbus.

https://oscarliang.com/ppm-sbus-d4r-ii-x4r-sb/

But I can try cppm. If it works i would be happy.

[horstrainer]

Hello norwenkel,
I am using the X4R sb.
Firmware is the one with lbt. More precise info is coming tomorrow. This one has sbus afaik (not cppm).
In the receiver tab of cleanflight everything is working as it should. That should show that its not the wrong firmware in terms of cppm or sbus…
Thanks for the input.

[horstrainer]

Thank you very much for the input!
I will try this tomorrow.
Isn’t it even better to try it without telemtry? Or is telemtry needed?

From what I remember, everything should be like you mentioned, but i will check and doublecheck that and will go through this process again.
Maybe I can try it in the morning before work.
Thanks.

First FPV-copter, so I went for everything as stock as it could be to minimize the first mistakes. So nothing special about the setup.

BUT I wonder if anybody out there had the same idea like me.
The shape of the MiniTri and my affection to planes with a painted shark mouth let me make the beast a bit more like a beast
…and this finally reminded me at the bombs from Super Mario!
