ArduHeli more information Please

Thanks in advance for any help
ArduHeli is this different firmware designed more for helicopters using Pixhawk controllers?
I am reading bits and pieces about ArduHeli but no real information about it?
Thanks

Read through articles and I think it will take some time. I am also webbing the info here and there.

Also Mr. Bill Geyer was very kind to answer questions.

Hope this helps.

There is only builds for Pixhawk controllers at present. It is a development fork maintained by me, used to fix bugs, incorporate new features into ArduCopter, and fly and test those new features for extended period of time on a stable codebase that does not change until new tested features or bug fixes are merged with it.
