Copter-3.5.0-rc8 has been released for beta testing

@cala2 i saw that my I values weren’t close to the new IMAX, so if yours are at max then yes, your tune would change.

@rmackay9 @Leonardthall

I hadn’t flown my tricopter since 3.3, so i am a bit behind. I reconfigured everything from scratch, did autotune 2 times to get a nice tune (i always do that and i feel like the first tune gets it close, but the second tune ontop of the first gets it all the way).

Flew:
Stabilize
AltHold
Position Hold
Drift

600mm Tricopter Frame
10x4.5 propellers
2216 800kv motors

I think the new release will be amazing, and i love the new position hold autotune, makes life sooo much easier. It’s pretty cool to watch it turn into the wind and in the yaw part of the tune do a little circle maneuver :smiley:

Thanks to all the guys that make this firmware possible, sorry you guys had such troubles last year.
Thank you Randy <3
Thank you Leonard Hall <3 (i think you did the tricopter specific improvements, sorry i didn’t test until now)

Hi Cala,
No you should not have to change your tune with the filter or I MAX default changes.

Hello,

First try with Navio2 and 3.5rc8 today.

Stabilize is OK, Altitude Hold and Position Hold OK, RTL is OK.

Here is an onboard video:

Myself and several others have loaded plain old RC8 onto our green cube equipped solos. No custom build, no baked in defaults from ROMFS. Just 3.5-RC8, and load the required parameters. It’s flying great!

I am still having same seg fault on different Erle brain3 consistantly :frowning: The 3.6 dev version would have the same issue too. Tried running with gdb(no issue), running with --debug version (no core dump file generated), so I am not moving forward… Hopefully this problem could be resolved soon.

I flew again yesterday with rc7 and twice had the “home location updated” message while in flight. At RTL the copter tried to go back to the flight location, not the arm location. Is it just me?

Did you take off before the GPS was ready? That’s what happens if you do that.

No. I always wait for ready to arm in PosHold to avoid that issue.

Strange. Can you post the dataflash log to be looked at here. Also, your post says RC7, but we’re on RC8 now. @rmackay9, this looks troubling, but never seen anyone else have this happen before either. What would cause the home location to change multiple times in flight?

Same here (“home location updated” message while in flight), some weeks ago on a small pixracer quad. Will check I find a log and make a test with rc8.

Can one of you create a new post in the 3.5 forum for this issue? Please include details such as what vehicle, what flight controller, what firmware, and post dataflash logs.

The best practice i have developed is to have geo-fence on the separate switch on my Taranis. This way if I have a need just to start drone quickly in alt-hold, shoot some scenery and quickly lower it down - it is doable with no wait time to lock into GPS. In the usual scenario you flip switch for geo-fence up and vehicle is not going to arm until it properly locks into 3D GPS - that in combination with RTL function properly configured more or less guarantees that you will not have any issues and it will return where it started from.

Iam currently testing Boat Mode with Coptor 3.5.0 - RC 8 with green cube on Solo using Solex. I note that when setting INS_GYR_CAL to 0 via Tower and rebooting, the LED sequence stops at the Blue disco lights and does not complete the initialization to Red/Green White/Yellow. Solex will not control the LED’s and is not in control. Using Tower, that will arm Solo and the solo controller will allow flight in manually or stabilize.

Has anyone really managed to make boat mode work with Solo,green cube and 3.5.0 - RC 8? If so how?

I have a boat ready for testing and want to see how EKF2 will deal with movement on open seas. I have perfected hand catching without any finger loss.

The LEDs staying in blue strobe under those circumstances is something I need to fix. The LEDs are waiting for the gyro calibration to begin and then complete. With the gyro Cal disabled, it never happens and they never switch out of blue strobe. Despite that, the solo is operating normally. It’s just the LEDs that won’t do their thing.

Thanks, look forward to the fix. The problem is compounded by the Solex not being able to communicate in this
mode so cannot turn the blue lights off which disrupts the video due to the flashing.
I also note that continuous movement is still causing a similar disruption.

What do you mean solex is not in control? It won’t be able to stop the LEDs because mavlink override comes long after the initialization stage. But you should still have all other flight controls and interfaces.

In the meantime, I suggest some black tape over the front lights :grin:

HI all … I have tested rc8 with various flight missions, manual and auto it seems fine … although now I have to switch the retract switch twice before they retract up PITA… how can I set this back to flip switch and retract directly?

I will be testing with Navio soon just waiting for motors to arrive for new “safe frame” we designed for the Polytechnic.

I’ve just moved up to 3.5.RC8 as advised due to fitting a Pix 2.1 to my big copter and it flies like a turkey.It’s actually scary.It flew nicely on a Pixhack with 3.4.6.So I posted a seperate thread in the Pixhawk 2 thread with logs and wondered if anyone could have a quick browse and see why it’s now so bad.Thanks.

Flew a few batteries today on rc8 - did not get any home position updated messages.
