Dronin on Rcexplorer F3FC integrated board

I’ve deleted all the previously posted links and replaced them with this one:

It’s a complete Dronin installer with the latest flight firmware for the F3Fc. It’s based off this repository:

I’ve pulled it down. Is there and real difference to the last one I flew other than it’s all rolled up into a tidy package? Heading to the dome tomorrow to fly but not sure I’ll have time to switch beforehand.

Cheers!

Same stuff, just wrapped in a single package now. No need to change what you have loaded now.

Does not seem to be getting a good in-flight tail-tune. I get 3 long beeps during the armed tail tune…. but when I disarm, it gives 5 long beeps for done fail, instead of 5 short beeps for done success. Thrust factor is still set to default.

If you’re getting to the point where it emitting 3 long beeps waiting to be disarmed, then it’s collected all the data points, which means it’s detecting the sticks in detent and the yaw gyro is below the noise threshold. All good there then.

So I think it’s computing a trim angle that is out of range, at least that’s my guess. To rule out a settings issues, here’s some screen shots from one of my tricopters, this one is using a DTFc flight controller with the BMS210DMH servo and the feedback connected. Here’s the triflight setup object:

Here’s the status uavo with the the servo command at neutral:

Serov is pointing straight up. Next is a full right command:

When viewed from behind, the servo is at 45 degrees. And finally a full left command:

When viewed from behind, the servo is at 135 degrees.

I’m curious if your ADC readings and computed servo angles roughly match, taking into account setup differences between airframes. If you have a logger can you take a log during the tailtune? I could then run that log thru a matlab script and see where the calculations might be failing.

Went back through and double checked all the config… Didn’t really change anything other than slight adjustment to the servo end-points and re-ran the table top tail-tune. Went out to the field, and it completed the tail tune on the first try. Thrust factor came out to 4.1 Flew pretty good. Was just banging sticks with no real purpose.

Still playing with this and have been comparing native dRonin tricopter to the development build with the TriFlight code @jihlein has been working on. Flying today with an autotune done indoors in clean air and now with the dynamic yaw compensation enabled (min 2.35 / max .5)

Cheers!

Nice work, Litterbug. Question: what OSD are you using and do you know if it is compatible with triflight? I want to use it for PID tuning and to report voltage, current and flight time during flight.

[LitterBug]

@marloth-ausgmail-com I am using a micro MinumOSD running MWOSD 1.6 firmware. Need to re-upload the fonts as it appears my battery indicator is messed up. It works with all *flight variants as well as dRonin.

Cheers!

Thanks mate. Do you also use it for PID tuning?

[LitterBug]

I’m pretty sure you can do PID tuning with the correct stick commands. It shows the stick sequence on the boot screen when the OSD starts up. I use autotune with dRonin and do everything through the PC Configurator so I have not tested it with the F3FC.

Cheers!

Bringing life back into this thread. Been testing a new version of dRonin with the latest TriFlight routines merged in. Here’s the result:

FYI…
@jihlein is still playing with this on the latest release of dRonin (wired)

@LitterBug Is that on the RCE F3FC? That is looking really smooth. I am compiling notes now, and got a board to bench test with – no guarantees on when, but I am so going to test dRonin on the baby tricopter, even if it isn’t the latest release 🙂

@jihlein The link for the installer no longer works. Has this has been replaced or superseded?
