"Jason,
Will changing the code to utilize gps instead of barometer or mixing the two a simple operation like changing the value of a parameter? The ardupirate code which used gps for altitude hold seemed to work with less variability. Posted a…"

Traditional helicopters in 2.0.38?
Started Aug 1, 2011 0 Replies 0 Likes
Is there still an option to fly 2.0.38 on a traditional helicopter frame? I don't see the 'heli' setup option anymore on the cli. Nothing I see in the change log leads me to believe this has been…Continue

In ArduCopter_2.xx is the barometer still mixed with GPS altitude? I'm asking because we are seeing huge errors in the altitude as soon as we get above sonar range. We have done two different tests,…Continue

We are running ARducopter_34 on a traditional heli setup. Stabalize mode works awesome but Alt_Hold is still not working that well. We're working through this issue, but we noticed that when we…Continue

How are people setting up thier radios when flying traditional helis using arducopter? In the setup it says to use Airplane/Acro mode, and connect channel 3 from the receiver into the ardupilot and…Continue

John Locke replied to malcolm churn's discussion 600 size heli"Good luck with Alt hold. Chad and I spent several weeks on it and never got it to work well. We tried multiple sonar locations, shielded sonar cables and even bought a second IMU board because our barro was giving out suck noisy…"
John Locke replied to malcolm churn's discussion 600 size heli"Huh. We have been running the tail and external gyro as if we nada 'normal' heli but had the gyro enabled in the code. We may have to change that. Would it be possible to more clearly state what the consequences of using an external gyro…"
John Locke replied to malcolm churn's discussion 600 size heli"Hey all
It looks like the Pitch_Max setting is the same one we were playing with when we got rtl to behave a bit better. We set ours to 10 degrees and that worked pretty well.
Wears running 3.6 of the code at the moment. Looking forward to 3.9…"
John Locke replied to malcolm churn's discussion 600 size heli"I wanted to post an older (weeks ago) video of Chad and I flying in stabilize mode with our Logo 400. You can see we have a really solid setup in Stabilize.
You'll have to excuse Chad not wearing a shirt, it was over 105 outside that…"

"
1 meter seems the normal barometer output precision. Not as bad.
GPS precision with altitude is not very good. In the best case about 2 meters i think with active Waas correction."
Steve Smetters replied to John Locke's discussion Barometer freak out"John,
Did you ever find a solution to this? My altitude on barometer jumps around like crazy even while sitting on the bench. It will vary between -50cm to positive 35cm.... jumping in between all over the place."
John Locke posted a discussionTraditional helicopters in 2.0.38?
Is there still an option to fly 2.0.38 on a traditional helicopter frame? I don't see the 'heli' setup option anymore on the cli. Nothing I see in the change log leads me to believe this has been depreciated, but it's not working anymore. I really want to try out the new filters on the barometer and sonar as alt_hold has been a problem. Any thoughts?See More
John Locke replied to Jacob Marble's discussion Eclipse configuration for ArduPilotMega"I have the same issue. I was able to get part of this to go away by 'verifying' an example project in Arduino, but now I'm getting the 'No rule to make target "all". Stop.' This is in the Libraries…"

John Locke replied to John Locke's discussion Barometer freak out"Just verified the libraries. They are the ones that came with the v2.34 zip file and they all svn match those online. We're going to try and put the ardupilot in a plastic bag to completely remove and wind over the sensor. Don't think this…"

Developerjasonshort replied to John Locke's discussion Barometer freak out
"Odd, I've had much luck with the barometer. You can certainly go in a change it in the code, but I believe GPS has too much latency to do alt hold well. But I've never tried it. Are you sure you are using the latest libraries?"

- Hi,
I think I have the same issue as you with the 406a. it was giving me the same garbage ( binary ) fresh out of the box.
John did you ever get your gps working? I have tried everything... I am about to return the unit. just wondering if there is any hope.
thanks!
