ArduCopterMega, the next version of the official ArduCopter code, is flying well and will bring full UAV navigation to ArduPilot by syncing it up with the APM codebase. Right now Jason Short is testing it on different airframes. The video above is it running on a stock Gaui 330s frame, with default settings. Late in the video Jason tries some different PID gains, but you'll see there's a bit of oscillation and they're not as good as the default. Awesome to see that the code can handle quads of such different size (the Gaui 330 is about 60% the size of ArduCopter) with the same standard settings.

the smaller the frame the more oscilations i see.

someone else should load it on a mini quadcopter and tell us the results.

When can we expect to see ACM released as alpha?
Comment by robert bouwens on February 1, 2011 at 12:26am

@guntars

already visible in the svn.

broswe the source source code and you see arducoptermega.

Is the ArduCopterMega support Hexa frame?
Comment by robert bouwens on February 1, 2011 at 2:15am

hexaframes are support.

you may build one and provide us with all the details.

What's battery you use. I'm use Gaui 330x-s frame too. With 2200mAh (2S) it work perfect with default PID. No need to tune up. But when change battery to 2200mAh (3S) it cause oscillation.

I have been flying NG code with great sucess for GPS and sonar for position and altitude hold. I am starting to fly ACM but not shure how to tune PID,s as I cant conect to configerator and no Xbee suport. What do you sugest.

Having looked at the new code and loaded it to test (even if pre-Alpha) it looks good. The only recommendation I would make is in the APM_Config.h I would still stub in and comment out many of the config options such as GPS_PROTOCOL, etc. I do like the new test harness which works very well. Thanks for all your efforts.

Sarawuth: we use a 3s 2200 battery. But remember we're using the alpha ACM code, not ArduCopter RC2. It's got a totally new control method.

Jack, we don't recommend that anyone other than the dev team use ACM at the moment. It changes by the hour and is not fully documented. The dev team can't answer any questions about how to use it until it's released in beta.
