Hello there,

Yesterday evening times compiled my first version of Libre pilot and played at the CC3D , has contrary to expectations look works well . With the settings for Heli I noticed immediately that already so some errors from the Open Pilot GUI 15:02:02 were eliminated . That's great , I'm thrilled.

That sounds like good news,

I almost tried to update my CC3D this morning, until I remembered that 15.05. is missing the CC3D support. So well, I will take a look at the current LibrePilot git

Folks, I have to think of learning to complile software, certainly is not anything complicated, and many years ago I have tried compiling the Linux kernel.

Hi there,

are there any recommended/tested values for the tail servo (yaw) stab settings for a 450 class heli?
I tried a variety of settings but tail is still unstable...

best regards,

Andre

Unstable:  oscillates?  drifts?  ?

You should probably start with AxisLock mode on the tail.  It is better at holding a locked position.

Then you should look into tuning PID's, in particular the Yaw PID.

Hi Andre.
Usually medium/large size multirotors suffer of tail wag.
You have to increase the yaw PIDs without fear of overdoing.
I've always had the red flags in the Basic tab with my 450.

Update:

Heli is quite stable now, had to repeat the "level" procedure after FW update.

Observed another thing now.-

- operating with 3 servos on the swash plate in manual
- using curve 2 as suggested for collective pitch
- when I move throttle to zero, the collective switches to negative max, when I rise the stick
just a bit, collective steps to neutral (all 3 servos).

Not really a problem, one only needs to give the main rotor a bit of time to spin down
before setting throttle to zero.

I am running  "next" 20151106 21:22, release 15.09 showed the same effect.

Best regards,

Andre

Is it still needed to configure the neutral servo position near to the minimum as described in the openpilot forum ?

Hi,
I am in the same process of setting up my 450 Flybarless with the cc3d.
I used the instruction as per the setup in this page: https://frickelnundmehr.wordpress.com/

I am having the same issue where mid sick, the swash jumps up to go back down when I lower the collective. Or it does the inverse, it jumps down and goes backup up when i raise the collective.

Not sure where this comes from?
I did level the swashplate, and tune the radio...
Thanks
D

Since a picture is worth a 1000 words, here is a video of what happens...

My HK250 did that once, too.

Make sure in Configuration / Vehicle / Curves that you see    0,0 .25,0.5,0.75,1  and -1, -0.5,0,0.5,1
And make sure you use default throttle curve, D/R, and pitch curves with no tail mix when you do manual calibration of your TX - failure to get that might cause your swash trouble.

I think the problem may be in your curve settings.... make sure you don't have any curves in your transmitter and reset your curves in CGS as well see attached picture. I made a little instructional video.. see if that helps. once you get the hang of it,.. it is very easy to setup this controller. I have 3 helis with cc3d, two 450 size and one 600 size...

Hi Guys,
Thanks for the pointers.  I re-checked and everything is at it's default.
Here are my settings.
I checked on my remote and i see that it shifts at -5 and not at 0 if that can give you a clue... (-100 to 100) is my channel.

[daveapplemotors]

I noticed this in you UAV under HW Settings:

<field values="5,2,3,4,6,1,9,7,8,0" name="ChannelNumber"/>
           
It seem to assign channel 5 to the throttle.
What happens if you try this:

<field values="1,2,3,4,5,6,9,7,8,0" name="ChannelNumber"/>
