Will moving the linkages further out on the arms help with flying outside? I just can't keep it in 1 spot with the slightest breeze. More pressure against the swashplate might help ?

Man, hows that for good timing!!!!! I'm just working on this very issues right now.
Like you I found my CX2 can't penetrate against an almost imperceptable headwind, even with stick bending full forward cyclic and prayers to the Almighty. To take her rear body off, if you can't pull her rear landing gear legs out you'll have to drill two small holes underneath to allow your screw driver to get to the tiny screws in the rear of the batt tray. Once her innards are exposed you'll see the links from the swash to the servo arms go in the closest holes to the servo screw, which is minimum travel. Not being too brave or wanting to cause binding of the swash I decided to move the links out by one hole, which will need to be opened up a little. The Z bends in the servo arm were also a little to tight for good control, so make sure that, whilst not sloppy, the new holes are an easy fit on the link wire. Not also, you may need to re-align the swash a little - just make sure the swash looks level by eye across the heli and maybe a slight tilt back cos this bird is nose heavy when the batt is in her. For perfect trim you could go to the trouble of adding a little tail weight until she balances under the main shaft then the swash can be totally level in the fore and aft direction.

Now the results! WOW! what a difference the cyclic response is far more powerful and yet she is still real stable. I hovered her in my 10x10 lounge for a whole minute with not a single touch on the cyclic stick - good enough in my book :D

I can't wait to try her out outdoors now - I am sure that increased response will allow her to bite her way into a slight headwind - not great perhaps, but far better than before. So, yeah, go ahead and move that linkage on the servo arm - works for me. BTW if you are brave enough to go out bu two hole positions and it still doesn't bind, let us know how it goes :D Good luck mate!

I went to the second hole with mine and really enjoy the new response I get, but I also found out that a quick move can cause my stabalizer bar to hit the blades. I cut off the curved ends of the stab bar and rebent the bar for the original weights and rubbers. It seems to hover the same clam way, but I have not got to fly it harder yet to see if I still get a strike.

BE careful, even with the adjustments the CX2 wasnt designed for any kind of wind at all. maybe 1-3? Maybe. I had mine 40' up with no wind, got a slight breeze and wam right into a tree. I have my linkage moved out to max.

I have read that blade-clash becomes a problem when you move to larger cyclic inputs and in wind so some people fit an after-market main shaft kit that increases the spacing between the two sets of blades. YMMV.

I'm just on the 2nd hole out for both the servos right now. 1 was set that way when I got it, so I figured I should move the other as well.

I have a new tail due in today, perhaps that will help the issue on flying outside a little bit.

I'd hate to have to leave this one as an indoor only flier.......

Ok, tried mine outdoors today with the links on the second hole of the arms.
YES, definitely easier to control in a slight breeze, for one thing you can get a more nose down attitude which helps penetrate into a wind (plus more forward speed when its really calm). She was hit by some gusts of upto (I'm guessing) 4 or 5 mph. Until I moved those links out, that kind of gusting would have blown her away into the neighbours garden, but now I've got enough cyclic to fight back.
Ok, its needs a lot of stick stirring to retain control, lets not pretend it makes the heli sit still in the wind, it Don't, but you get a better chance to keep control.

No matter what mods you do the wind is always going to be a factor, the CX and CX2 are indoor helis as with any other co ax heli, I even have slight trouble with my T rex in certain wind speeds
