Ok, Ive searched this one and saw that some people had the same issue, but reversed. My cx-2 seems to want to go right (clockwise) all the time. Ive turned the trim, and the proportional pot, and still always wants to go right. I can get it close. but when I get it close to center, then it has alot more power turning right then left. Is there anything I can do adjustment wise other than the transmitters trim and the pots to help it stay centered when Im flying neutral? And has anyone been able to get theres to turn the same speed right and left? Ive had a cx-2 before and it always turned right alot faster than left. Or is this just the natural tendency of a coaxial bird? Hope someone cane help and Thank you!!!

It is normal for the CX to always rotate faster in one direction than the other.

Ok, so I decided to figure this out again. I took it up for another flight, and this time I could actually hear that it wasnt right. I really dont know how to explain it. But it sounded like it was pushing a whole lot of air but not moving accordingly. (Like a car with a slipping clutch). I put in a fresh battery and it was a little better, but still wasnt sounding like it should. So I narrowed it down to a blade issue. So I took them all of and inspected them. I noticed that on both the top set and the bottom set the blades didnt have the same curvature. I grabbed some other blades I had and through the process of elimination I found that a few were a little off in the way they curve. I installed the 4 I had that all were the same. And to my surprise now it was turning to the left too much. Which was good, I now knew it could be fixed, just needed some extra tuning. I reset everything back to neutral and made adjustments to the trims and pots, and got it perfect. Not only did it hover correctly, by turning the gain counter clockwise I got it to turn to the left and right with the same speed. Before it had about twice the speed and power when going clockwise. Now its the same both ways. I took it outside for a flight and its so much funner when its working right. !!!!

If I would have jumped in here sooner, I may have saved you some work. But you got smarter on your own, so maybe that's better!
Anyhow, these coaxial helicopters are really sensitive to tracking. When you look at the edge of the rotor blades as they spin, they have to cut one line. If you see one is higher than the other, the tracking is off and the heli makes a decent fan, but it will hardly fly at all.
You know that the upper blades can be adjusted via the flybar link. The lower blades are victims of the curvature of the blades - as you said. I suggest boiling all of the blades to allow them to return to normal pitch, and then you should be good to go.
The blades come from the factory in good shape, but when they are shipped to the US in boxes weighing several hundred pounds, you know they'll get squished. Just boil a pan of water large enough to hold blades, dump in a couple and leave them for a few seconds - long enough for them to be heated all the way through, then pluck them out and hang them vertical for a bit - in under a minute they are cool enough to hold their shape.

Here's a link to a bunch of good information. Learn it all and you'll be simply brilliant.

I have found with these cheaper helis their is just no point in trying to get everything perfect.

The heli will never sit perfectly still in the air.

If boiling the blades doesn't help.

You might want to take the heli apart check for bent shafts and test both motors...

Not true. If you are careful and get it all good, these helicopters will hang in the air like they are hanging on a string. I put mine over the driveway one night, walked 10 feet to put the Tx down, walked back to the helicopter still hovering right where I left it and I pushed it around the driveway with my finger. It went wherever I pushed it. Then I walked back to the Tx and flew the CX to a good landing spot. That was with a STOCK CX. Not a CX2. It was all original. I just took my time to get every detail correct. You will not get that steady hover indoors unless you are in an auditorium or warehouse or gym or some very large place with dead air. I got the good hover outdoors on a calm night. My best flying has been on fairly still nights outdoors.

I have flown the CX in five mph breezes outdoors without problems - after a few minor modifications. I DO NOT recommend that for first time fliers, but when you get the right combination of weight and battery power, it works OK.

Soloboss, I agree completely. I have mine so well balanced out now, that I can fly it in my driveway if theirs no wind. And I could sit down under it like it was a fan and enjoy with cooling. Now like you said this only works outside in my case. (Since I have no indoor areas to fly other than my garage) But even in my garage if I get it high enough and out of the way of anything that can interfere it hovers perfectly. And the TBE is gone also now. It just took a good studying of the blades and picking the best out of the bunch I have. The guy that I got this from sent me a set of aftermarket blades that say cx-2 on them, but are a different configuration. They have only one screw hole on the top. So I need another aftermarket part for these to work. I already bought the aluminum bulkheads and swashpplate, so Im thinking if I wanted to run the aftermarket blades that Id have to get some more parts that would defete the purpose of why I bought the eflite alum parts. Whats your experience on the different blades? Are they any better? Stronger or better performance? Or should I just stick to blades that will fit with the way I have it set up now? Thanks alot!

Ok, I see how they work, they actually dont replace the bulkhead, they just make the blades a 2 piece instead of just one. So I could just get the pieces that go from the bulkhead to the blades, and that would allow me to use the other set of blades I have? So Ill ask the same question, Is it worth switching to this? Or just keep running the one piece blades? Thanks again

Have you guys seen this site and watched some of the videos? http://www.flyrcrivesud.com/upgrade_parts3.html

They make some pretty bold statements on how their parts will improve performance. Is it really possible to increase your forward and reverse speeds by alot? And if so are you doing this in exchange for stability, like a trade-off one for the other?

Hey Custnam,
About the flyrcuseud or whoever they are, there was a pretty severe episode some time back. It involved unsubstantiated claims and counter claims from our forum members and it got pretty ugly. I got enough garbage emails from them that I just blocked them. And I admit that I've slept just fine since.

If you want durable blades with better than stock lift and the advantage of pivoting mounts (called blade grips) I recommend the goodies at Xtreme. I had them. They work. They like the stronger Xtreme 180 ball bearing motors. And they REALLY like the 180 motors with replaceable silver brushes.

As far as those other guys, I've sort of wondered what happened to them. Maybe you should use your money for a significant upgrade and full report back to us!! LOL! In these days of video editing there is no way to know how the test results actually turned out. I have yet to hear anyone who is impressed with their stuff.
