Excellent. Thoughts on the pixhawk clone? ANything you would have done different in the other components?

Also, more video of the Position Hold when you get it tuned please!!!

Currently I'm happy with sll the components. I will test to flash the ESCs with BLheli fw though.
There will be more videos. Going to London on vacation for a couple of days but will fly again as soon as I'm back in Sweden.

Heh heh, me too!

Had a problem on my second flight, one of the motors continued to spin after disarm, managed to solve it after some googling.

APM:Copter 3.3-rc1 was released yesterday so I upgraded the Pixhawk and started to test.

AutoTune

[Vermiform]

During autotune, are you able to nudge the multirotor back to the center of your flying area from time to time or does it cancel the autotune routine if you touch the controls?

 

[mackar]

Yes you can relocate your multicopter without canceling the autotune.

Got a reply from the APM:Copter developers about the Autotune

"The release went out with AUTOTUNE_AGGR set to 0.05. This tends to be a little sensitive, the default should be 0.1."

Haven't watched the video all the way through yet but I really like those leds, so easy to see.

Where did you order those please?

Thank you.

I hope the retractable legs arrive soon so I can start testing the new functions to retract them implemented in APM:Copter 3.3

 

[mackar]

Got my retracts and have attached them temporarily, they retract as they should but I'll have to modify them since they bend to easy.

APM:Copter 3.3-RC3 is out now. There were some problems with Autotune in RC1 so I did a new Autotune, didn't really work as I hoped

 

[Vermiform]

How much wind?

 

[JoeBob]

Grass is good.
Pavement Autotune =
View attachment 24530
Only because I have no pride will I admit that not having a Kill-Switch when landing a failed Auto-Tune cost me $40 in props. Bent RX antennas (straightened with fingers) and scratches on my Ublox Neo M8N, but nothing else serious.

3.3 experience with my Pixhawk DiscoPros:
One flew but drifted bad. Pilot error to use 'Land' instead of Alt Hold to get it down.
The other barely spun up, like your bird refusing to gain altitude.
Check your radio calibration; endpoints and throttle center.
Check your ESC calibration.

Love the grass!

[mackar]

My problem was user error. Wasn't in AltHold when I engaged AutoTune.

Just got a reply from one of the developers and it doesn't have to be in althold anymore. Will do a new test later today if it doesn't rain.
