I'm almost ready to maiden the 7HV (finally). Noticed a few things with the tail, most troubling is the drive train does not feel smooth at all. If I spin the main blades, the tail rotates but it does not do so freely and the whole drive train feels notchy. Compared to my Furion, if you spin the main blades, they (and the tail) continue to spin unencumbered for a little bit and it is smooth as silk. Not the 7HV, it stops immediately and is notchy. I checked the belt, only one 90* turn. Any ideas?

The manual I have is for the v1 tail. I cannot find a download for an updated manual for setting up the tail. I set "zero" position so a line drawn through the two bolts that make up the pitch slider mechanics is parallel to the tail case. In this position, there looks to be a lot of pitch to the tail. I did not measure it (I will) but it looks to be more than 6-7*.
Thoughts? Did I do it wrong?

My 7HV will not freewheel as much as My whippy, but thats normal. When spinning it shouldn't feel notchy but again you can feel there is a belt.
