DSC00590.jpgThis is the position of my servo arm at 12° negative.
My servo arm seems to be a little 'higher' (more anticlockwise than yours at 12° postive).
But.......t think I have fixed it!
My main problem was that I was binding at about 3/4 high stick, so if I adjusted my swashmix so that this didn't happen then I wouldn't get full travel at negative stick, i.e. nowhere near enough travel from high to low to get near +/-13°
As I couldn't adjust the A arm, I decided to offset the elevator servo 'wheel' (sure that's not the right term!) by about 5° anti-clockwise:
(this is at mid stick)
I can now get full travel from high to low without binding at +55 on the swashmix.
Once I got everything levelled out again and at 90, I was actually able to get far more than +/-13, had to knock the swashmix down to +40.
So all in all I'm happy, but just not sure if what I have had to do was to compensate for something else in the kit/build being wrong.
Thanks so much for your time in offering help.
Good good good,if the next photo is one of it flying better still.
I too followed the manual when building the 600N v2 le and got the same outcome. Not enough range on +ve pitch. Everything is and was ninety, swash level. Then I took the head off and dropped a swash leveller/balancer (Turnigy 600) on, of the type that sits on the swash's prongs. And bingo. Though the swash was level, it sat as it turns out, about four turns higher on aileron and pitch sides when compared to the manual. So having adjusted links so that the balance tool sits on elevator as well and reset all other links per manual, I'm happy to report plus and minus 13.5 degrees, zero degrees at mid stick. And no binding; could get 14 degree each way I think with a push.
So for you guys who had, or are having problems; eyeballing swash levelness is/ or maybe ok but in this case it needs to be lowered onto the elevator A-arm link to get full range. Give it a try and let us all know how you've got on.
I could be reading this wrong. But how can the swash be level but then you have to adjust the aileron and pitch sides 4 turns to get it right? It must have been sloping towards the elevator to start with if you had to give aileron and pitch 4 turns to then become level with elevator?

I've never used anything but my eye whilst leveling the swash on any heli. I am very carefull o make up my links though to the exact measurements in the manual & build it from the bottom up. Works for me & boy does the v2 fly like its on rails. Just can't get enough of mine but I'm o ly using plus & minus 12 degrees any more than that & your going to kill your head speed & big the motor in pitch pumped maneuvers.
Just to clear things up a bit maybe. It looked level and with the tool still looked level but it, the levelling tool, wasn't resting on the elevator's swash prong. And so I adjusted the other two shorter so that all three prongs of the tool rested on those of the swash. Hope that makes sense.
If I knew how to upload pictures, I would that of the tool I'm talking about.
I have today found this link; and shows how the tool was used.

Hi guys what swash mix settings did you start with?
I'm having same problem.
I started with Futaba's 10CGH default 50% then reduced to 18% for no binding and got 5 to 7 degrees +ve pitch. Got 10 degrees negative. Since balancing the swash with tool my swash mix is around 28% and I'm getting 13.5.
Before using the tool, my swash for all the world looked level.
Cheers Leicester managed to sort mine out by adjusting the two long links by 2mm first to get 0 degrees at mid stick with swash at default 60%. I then reduced pitch down to 32% now get my 10 degrees either way.
May consider getting a swash mix tool.
