Default RE: problems with my cx2

Well, if it's supposed to move like that within a 1 foot span, than I think it's okay. By "dancing", I mean that it rocks back on forth, it will fly forward about 8 inches, then fly backwards about 8 inches, almost in a rocking chair pattern. Sometimes it makes flys in circles without any stick movement. What do I have to do to break in my new engines. I'm new to electric flight, so this is all brand new to me!! Thanks for the help!! As for some of the other things: I haven't changed blades, it still did this with my old stock motors, max flying time is between 10-15 minutes but I can't do much flying right now because I have to fight it to keep it on track. I've tried to trim the radio out, but it still moves even after I've maxed out the trim. Also, when I give it left rudder, it moves really slowly, but right rudder is fast as normal. The heli doesn't have a lot of hours on it, all in all, I would say it probably only has 1 hour on it.
It's sounding like you may have a flybar that is binding and probably a little bent. Check for proper operation of teh flybar. It should be loose enough so that you can flick it with your finger and have it bounce up and down a couple of times. Another thing to check is blade balance. Have you done that yet?

You do not strictly HAVE to break in new motors, though it's better if you do. With your other problems, let's leave that aside for now.

10 - 15 min. flight time is great! It's hard for me to believe that you're having all of these problems and yet you're getting more flight time than a lot of us with perfectly operational Helis....

It is normal for the Heli to turn (yaw) faster one way than another, though with your prop mix pot properly adjusted and with a fresh LiPo, there shouldnot be that much difference. Try this, put your Heli on a surface clear of othe robjects, like a workbench or kitchen table. Turn on Tx and plug in battery. SLOWLY raise throttle until one of the shafts starts to turn. Note which one it is. Ideally, both shafts should start to turn at the same time, or very close to one another when raising the throttle. If you notice a large difference between the two, then your Prop mix pot on your 3-in-1 unit needs adjustment.

The bottom line is that flying a Heli does require that you actively control it. To get one of these Helis to a true hands-off hover can be done, but it takes a lot of tuning and perfect parts.
