"O.K been flying today and there was a strange incident when switching to loiter again, where it shot off in the wrong direction, so tell me exactly what file you need and how do I know which it is? I dont have wireless telemetry?"

Dave C replied to Randy's discussion ArduCopter 2.5 released!"Sunshine! Yee haa!
And I've been flying my tri about in acro - in a 3*3 garden!!! Then nose-in hovering in stab. It's making me a better pilot this APM :)

Dave C replied to Randy's discussion ArduCopter 2.5 released!"Go for it, I've just done 6 batteries in the garden with those params, tried a bit more tuning but have ended up back where i started. It's a joy to fly, inch perfect.
I'm vibe reducing now, (strenghtening my shaky frame) then…"

"Wilson,
Hard to say what is wrong. It could be so many things - compass not working, PIDs set badly...really hard to say. I think it's better to ask around on the forums so you get more opinions than just…"
Dean Wynton replied to Randy's discussion ArduCopter 2.5 released!"Weathers looking good down here, might creep out and try your params Dave?"
Dave C replied to Randy's discussion ArduCopter 2.5 released!"Yes, a well tuned tri is very nice to fly, it feels like it has a definite 'forwards' compared to a more symmetrical quad. For info I've only ever used 3s."
Dean Wynton replied to Randy's discussion MPU6000 scaling issue"Are you using apm1 or apm2?
Cual tienes? apm1 o apm2"
Dean Wynton replied to Randy's discussion MPU6000 scaling issue"Maybe I missed out some of the patch somewhere? as it is much better now..
I haven`t been able to reproduce the compass bug or has it happened again so far? If it does I will be sure to send you a dataflash.."

"Dean,
There's only one additional fix that's in the mission planner version vs the 2.5.5-Beta patch that I posted ahead of the release. That fix is related to the TRI servo so it shouldn't improve the…"

"Andke,
It sounds much more like your compass is not working at all. By default the APM assumes that it's facing north when it's booted up but it updates to the correct heading when the first compass messages…"

"I will be there!"
Mike Mac replied to Randy's discussion ArduCopter 2.5 released!"It’s fixed now. Looks like the Mission Planner was pointing to the old Y6 file and now it has been changed to point to the correct file. I loaded it this morning and will fly it in the next day or two."
Glenn M replied to Randy's discussion ArduCopter 2.5 released!"Cheers for that. I've just put nx-4008s with Gemfan 11x4.7s on my tri (running 3s for now, will be on 4s next week), so I'll have a go at tuning it according to your guide.
I do love the tri compared to the quad! I'm building a…"

I've had chance to play with the tri a bit more, again only rate and stab tuning, but I think I have discovered a really nice way to tune the APM for tri, at least for mine anyway.
I went down the rate_D tuning route - hand testing…"

ContinueTrex450 loiter testing using Arducopter 2.0.50Beta

This video is of some loiter testing I did this morning of my Trex450 running the latest arducopter code, 2.0.50.
If it were a quad I might not be super happy with the results but for a traditional heli, I think this is a pretty good performance. The altitude hold is very solid using…

Quad position hold with mouse sensor (reproduced)
Posted on January 26, 2011 at 8:00am 8 Comments 2 Likes
You might remember this blog post by Marko Klein Berkenbusch on using a hacked mouse sensor for position control of a quad. With some help from Marko himself, I've mostly repeated his results on a branch of ArduCopterNG and thought I should share how I did it as it's slightly different. Please note that this is not…

I have been working on my own Quad with the NG code and have setup the Sonar and have it working very well . I have an indoor version with sonar and IR sensors and would like to know were the IR sensors are conected, what pins. I see you were working on implementing this so If you could help with basic setup I can try my hand at testing. Thanks for your work on the Sonar and good luck on the obstical avoidence.

Thanks Randy.
I do not have write access to the svn repository.
So I will send you the changed AP_ADC lib probably later today.
I am not sure if a circular buffer is needed. The beauty of a 1st order IIR filter is that we only need one "old" sample and if a second order is needed only two old samples. But I will look a little better into the filter selection before committing anything to you.

Hi Randy
One of the way to introduce technology of arduino as IMU is that something like what you have done. Most of the Japanese model flyer love to fly traditional helicopter.
Another approach may be exhibit something very unique at MAKE fair at Tokyo Institute of Technology. There will be many open source hardware and software freaks as well.

Ravi said… hi randy, i had been following your forum for align450. i just got my APM2 purple. i loaded the ardu heli firmware. everythings looks to be ok on mission planner. but there is no PWM on servo out pins. i armed the APM2 and does gets armed. the radio callibration bars move proportionately. evrything seems to be OK. but in 'status' there is no PWM on channel out pins. it shows '0' PWM on all out channels. can uou please suggets what might be the reason. the APM2 works fine with arduplane and arduquad firmware. ravi

I had a different problem with my APM2 that I was able to solve by following the procedure found in the wiki with a search for APM board problems. My board would not connect to the planner and it works now.
Good luck

I appreciate your help
