blades are rail 716mm and rail 116mm.
I am using the CC gov. I also played with gov gains as well, I couldn't compound, or relieve the issue at all with the gov gain.
I run BD on my E5, so no, the tail has been rock solid. The BD probably has the strongest tail and best tendencies in FFF of any controller that I have touched. if they could get the elevator bounce worked out in the hard stops then it would be the perfect unit. oh, and piro comp like the vbar, that is really neat and I liked it.
I mean, I really like the way the vbar feels, but the tail is killing me! I get the fact that the heli has to be flown constantly, but I flew a guys N7 with a CGY750 on it, and the tail was right where it was supposed to be the whole time when I was flipping. another thing I like about the vbar is the pitch pump speed increase. that really helps with tick tocks. on tick tocks it wants to walk left too (tail [nose right] and whole heli too).
