Ok, now that I got that out of my system. It's been a while, so I don't remember the exact difference, but the B400 has a different head, than the HK/TREX helis do. So the information in the pitch curves is backwards from one to the other.
While the wife is out hiking with a friend of hers, I'll break out the helicopter, the DX7, and the flymentor. I'll see if I can get them all to be friends, and I'll try to make sure to document it all.
I might have to do it in the living room though, the workshop... ugh, the workshop....
