so Nitro wing your saying a battery brown out or weak power would cause a snap at the top of a loop ? sound's like crap to me ...... to me that would be more mushy and slow servo speed and or blow back ,, but hey what do I know, logically you would think if the battery went weak you wouldn't be gain more defecltion its more likely you would be losing deflection and it wouldn't account for uneven deflection .. I'd be wondering what's up with the duel elevator servo set up seeing someone changed 3DHS original set up and most of the time there set up is spot on , I'm beating this guy bought someone else's problem.....the slick is a great flyer I think we can all agree there, I fly the same plane and i knew something was super funky and I know the best bet of finding good information is the other forum .... I kinda don't like the fact that you fire blank information and what i consider misinformation out there , when a better suggestion was already Gaven .. and I'm pretty sure you don't even fly a slick do you ?
