Newbie here.... Need help with a T8FB and CC3D controller
« on: January 12, 2018, 10:20:17 am »
Hi all,

My apologies if this has been addresses already as I am new here. I am having challenges with a Sky Hero Anakin drone using a CC3D Flight Controller and RadioLink T8FB Transmitter on S-Bus. I am obviously using LibrePilot on this controller. For some reason, when I try and 'arm' the drone after setting Yaw Right as the arming option, it does not allow the drone to arm when I use Yaw Right. It just sits there.

The only way I can get the drone to arm is to set it to Arm Always which is obviously not ideal.

I was wondering if anyone could give me some advice on where to start looking to see where the challenge is?

Thanks

Ian

If board cannot arm there is a good reason, most of the time something wrong in configuration and a alarm in SystemHealth.

Please post post your config file.

Hello Forum,

I'm in the same situation. Arming did not work proper in first place (was functional on the working bench but not out in the field). And refused since than totaly.

Attached confic of my controler CC3D with latest firmware.

thx for help

You should first redo the transmitter wizard:
- Some inputs have a type set (Sbus) without channel number,
- Limits min/max are not consistent,
- Neutral for Throttle is not correct.

Even if you can arm, this Quad will flight very bad because every motor uses PWM-50Hz as bank settings.
This mean very slow Esc update and oscillations.

You should redo the Vehicle wizard and choose the right Esc type (Simonk, oneshot...) and redo the transmitter wizard.
Next you assign the Accessory# for arming.
Please note the board need to be steady during initialization after power up since the option "Wait until the board is steady" is checked in Attitude tab.

Stabilization > Basic > "Zero the Integral when Throttle is low" (at bottom page) should be checked.

Or

Could be that you have a dual rate set on some stick so that stick no longer reaches the "arming position" as far as the FC can see.

Also must be perfectly motionless to arm.  You can't hold it in your hand or even put it in the bottom of a boat because 16.09 has a feature where it waits until it is completely motionless before it will finish arming.

No Arming with CC3D controller

Hello,

thx for the input.
I did disable the not used sbus cannels to minimize the possible failures.

did recalibrate the reciver manualy, with the tool and changed the esc from 50/PWM to oneshot125.
restart the system and 'voala' the arming switch is working.
at least it is working in the hobby room, but the motors are flicking a little bit even when not armed.
recalibrate the 4 esc/motors, but they keep this behaviar.
may be the esc are not right programed (BLHELI 12A from KINGKONG)

Will try a test outside the next days

Esc maybe need to be reflashed with BLHeli but you can simply reduce the min value in Output tab to something around 980 or less (without re-calibration) to remove this motor behaviour.

Hello,
I just got outside to try the new setting and again the electronic did not arm.

So think, somehow I have a general problem with this batch of controler.
May be, comming from China, 5°C is to cold of them :-)

Will retest tomorrow and try also the ESC setting to 960

Is the board powered (led blinking) while the USB cable is not connected ?

Procedure for arming is Throttle to minimum and next use the arming switch, if Throttle is not to minimum the arming fails and you need to redo the on/off/on with switch.
Remove the option "Wait until the board is steady" in Attitude tab, just for test.

Hello,

so I tried the setting outside and failed again.
disaibled the  'wait for steady'
tried 'always armed' but the SW did not let me in the first place, it worked but is a stupide idea

now, even inhouse I can not arm

try to recalibrate, but same after that
See the input from the remote in the SW, also the arm switch

try to start from the beginning but think that will not work (did it 2 times)


thx

Thx for all your help

It looks like, that the ESC (BLHELI 12A from KINGKONG) did cause the problems

work around (I could not flash them) I did not use oneshot125 but 400Hz.

Now I can arm the FC and it is relatively stable, from my beginner view .....

so not good, but flying
