Just an annoying problem with the motors pulsing in Altitude Hold.I don't seem to be able to tune it out entirely. I've disabled the Sonar. The Quad holds altitude quite well but the pulsing upsets…Continue

I've been planning on getting a phantom for sometime but recently it was suggested that I look at the arducopter. I've been doing some research and like the 3dr quad and hex rtf version. But I'm not…Continue

Hi guys! Our quad is already build and programmed (I think so), and when we tried to take of for the first time, we noticed that it not stable, as you can see in this video:…Continue

HELP,

I have APM2. So far everything perfect, flying good, auto stabelisation of cam perfect.

But, when i want change value in MP for CAM_P_G and in CAM_R_G and then try to SAVE it or WRITE PARAMRS, it shows me a error, that it could not do it, if i change any other value for CAM_ .... it does not show any error.

Bradley.

totally agree with u,

threads start with a particular question or problem and somewhere get diverted to another topic..... so it damn difficult to follow, 

and it would be great if a thread would maintain its originality, there would be far less questions asked repeatedly and avoid clutter and confusion.

regards

Thank you Randy, 

Before I post a thread I am going to try to find something about it.  If I can't find it then I will.  Thanks for all your help

@Bradley,

>>Can I set Channel 6 variable to control a setting that would help out in the windy conditions and then tone it down when it is not so windy?

To be honest, i don't know enough (I'm not sure anyone knows enough) about how the loiter behaves in different conditions to give good advice on what tuning values should be increased/decreased.

 

P.S. I'm repeating your question because comments posted to this group are also emailed to people and they can't see the original questions because this group doesn't really act like a thread.  Sometimes, it's better to start a discussion.

Thanks Randy,

Can I set Channel 6 variable to control a setting that would help out in the windy conditions and then tone it down when it is not so windy?

@Bradley,

     Re your question:

>>"When you have channel 5 set on RTL should it return to launch and land? Or should it RTL and loiter?"

    the answer is that it will land after a while.  the amount of time it waits before landing is set in the "AUTO_LAND" parameter.  The value is in milliseconds so 20,000 = 20 seconds.

 

@Andre Kotze,

    Re the quad swirling in a clockwise direction when you go into loiter..it could be because your declination is off so it's missing the target of the loiter.  I think if you're swirling clockwise you need to decrease your declination.  Try decreasing by 10 degrees to see if that helps.

Also,  When you have channel 5 set on RTL should it return to launch and land? Or should it RTL and loiter?

First auto Flight today!  This is Kansas and we had some wind today  gusting to 28mph.  I thought I might as well try it because i very rarely get calm days. 

Quad took off just fine and then had a really hard time getting to its first WP.  So then I swtiched it to RTL and it came back and landed perfectly. 

2nd. Flight I took off just fine and then it drifted bad with the wind and then I had to put back in stable and get it back closer to me so I could land it myself. 

Can I set Channel 6 variable to control a setting that would help out in the windy conditions and then tone it down when it is not so windy?

When I put my quad in loiter mode it starts to "swirl" in a clockwise direction.  The circle gets bigger the longer I leave it.  What do I adjust?  Thnx,

New firmware (2.5.3) for AC is GREAT!  Its the most stable and smooth I have yet to see.  Good work Devel team and thank you! I am so glad I put my money and energy into ArduCopter.
