Has the CX2 been wrecked recently ? Do you fly outside or inside ? Does the heli balance perfect ? You can adjust the battery to help... Make sure your blades are balanced, and are tracking correctly. Also on your flybar it should be move quite freely. Flick it on one end, and it should flick back and forth 2-3 times...Sometimes, which I do everytime, ya need to use some light sandpaper to sand the "balls" on the flybar to get rid of the little extra flashing burrs that are on there. You would barely see them, but it counts for very smooth transitions of the flybar assembly.
For advanced users for more forward flight we shorten our flybars, and move our servo linkage rods out a hole or two. Gives more authority and nose in digs for a little bit better outside flights. Also you can move the batt forward just a tad to make the nose a little heavier to aid in forward capabilities...Remember stock, the heli is set up for indoors, and mainly for hovering, as they have in mind that a beginner is at the controllers. As you get better, and understand the CX2 more you can tweak it a little to obtain a little more performance (forward flight) but in return you'll give up a little stability, but you won't notice as your better than when ya started anyway (hopefully...Lol..)
But yeah, best bet would be to read Soloboss's guide and you'll then be certified, everything I mentioned is in there...But we're all still here waiting and willing to help. Seems you might have got lucky and came to the right place ...
Good luck...!
