Well, I guess it had to happen.
I was getting cocky, and flying it through a doorway, and WHACK! The rotor hit the doorway... Surprisingly, it didn't break the rotor, but it did break the lower rotor head.

Guess it's off to the hobby store. lol

... and of course, I had to do this on New Years Day. The only LHS that is open is out of lower rotor heads...

Oh well, I'll fly the sim, and head to a different LHS tomorrow.

If i may i would suggest getting the aluminum lower head. That is the one week point on the cx2.

I was considering that.
Oddly, the CX2 comes with an alum upper, but a plastic lower.
You'd think they'd have...

Oh well.

I use my wifes Lama V4 to chase the dogs and cats around the house. They get to running and I go after them full speed (at least as full speed as that thing will go) Done popped so many door ways with that, I bought three packs of both A and B blades. So far, all it has done is cut the last inch of two off the blades.

Chasing dogs & cats?!? LMAO!
My dog won't stay in the room with it, and he's to mellow to run, so I don't get much chance to chase him. Besides, I'm not THAT good yet.

Fun little habit to the CX-2 that I wouldn't have noticed if I wasn't flying outdoors. Since it's a coax, the bottom rotor is controlled, by the pilot, and the upper is controlled by.. the flybar.
When you nose it over into forward flight, it runs along for 15-20 feet, and promptly comes to a near stop as the flybar pitches the top rotor to cancel out the bottom rotor. Makes it really frustrating to try to make a fast forward pass. lol

I'll be doing a mod to the flybar before to long to get rid of that little problem.

But, as I also learned, air currents change when you're going through a doorway. I guess I'm not doing as well as I thought I was.

Guess I need some more practice before I try that again.

Well, ...

I went down today and picked up another outter shaft, and a new set of bearings. I thought that the other shaft was bad because after putting it in, things still wobbled, and it looked like the outer shaft was bent.

So, I put the second new shaft in, and guess what... Things STILL wobble. No, it's not the inner shaft doing it.

So, with some much more careful investigation, it looks like the upper bearing cup (the one that holds the top bearing for the inner shaft) is all out of round. If that's the case, it has been that way since it was new! What is frustrating about it is that I had my hands on an alum. one today at the hobby store, but talked myself out of it. Shoulda just got it while I was there.

So, I get to go BACK to the LHS AGAIN tomorrow, and get it.
The only part that won't be alum now will be the swash plate.
Go ahead, someone tell me the alum swash plate is better... it'll make me just buy the darned thing while I'm there and be done with it.

Take the blades and flybar off and spin it with the motor and see if you get the wobble. I'm not sure about yours but on the CP Pro the flybar is the main cause of wobble. I finally said screw measuring the things with a dial caliper because it never worked, they were too far out of balance. I finally just started sliding the bar off center one way or the other until I got it smoothed out. I would get the flybar where it didn't make the thing shake a wobble, then put the blades on.

OOOhhhh how I hated the CP Pro.

Thanks, but I already did that.
I did the spin test with the blades, and flybar off. So it was just spinning the shaft & heads.

My CX-2 has gad a wobble since brand new pre crash. I think it's the flybar that is doing it on mine. I increase The RPM and the wobble kinda works itself out and is eliminated with higher RPM

With mine it was the top bearing cup.
When I took the original off and checked, the bearing was very loose.
The new one is nice & tight, and the head shake is gone.
Well worth the $9.95 (for the alum. one).

So did I

...knew it was only a matter of time...stupid dry erase board jumped in the way when I was comin in for a landing in my office cube promptly dumping the chopper into the trash can...perhaps an homage to your thread after this one, 2old

Lucky for me, I have some fresh head gear and blades on the way and in the meantime, it'll give the thing some downtime so I can install the lipo alarm/lights...then the LED flybar with red and blue LEDs...think I'm gonna need that police shell for the CX2, now that I think of it...

Anyways, I like the idea of having folding blades on an indoor heli...just seems to make more sense to me than the rigid mounting of the stock CX2...hell, even the air hogs reflex has collapsable blades. LOL

I did read somewhere that the "xtreme" rotor shaft, blades etc weighs more than the stock equivilent, but I'm willing to risk it for a more durable assembly alltogether...hopefully.

Anyways, just thought I'd chime in with a "Me too!"

Happy flying!

Welcome to the club. lol

Mine is all fixed. I've replaced almost the whole upper end now. The only original part left is the swash plate, and I know I'm counting days on THAT too.

I looked at the folding blades option. Not a bad idea. The only reason I didn't do it (or at least not yet) is the lack of blades locally. I know I'd be the one who smacked his last blades into the foot stool, and then site & wait a week or two for more to come in. At least with the stock set up, I can get my blades locally.
Other than that, I really liked that option.
In fact, with that option, it might be fun to fab up a mold, and start making carbon fiber blades. Yeah, the stockers are inexpensive, but not nearly as cool as a set of fibers would be!
Then the carbon fiber tail boom.

But.. I will most probably not do any of that.
If I decide to stay in helis, I'll save my pennies toward something a bit bigger.. Probably a 50 nitro. I could take it to the field with my planks.

A 50 nitro is very nice, but I converted my Raptor50 last summer to electric, and its even nicer. After many years of nitro, which I do like a lot, I changed to only electric, and it different, nicer in some ways, but also a bit more expensive upfront, you´ll have to use a substantial amount of money in batterypacks, but then you only have to pay when you crash. :-)

Well, I figure it'll be awhile before I can consider pulling out the night ranger 3D micro again.
I'm hoping that with enough practice in the sim and with the CX2, the training gear I have coming in the mail for the cp and some pacification measures(read, moving the servo links in a notch, balancing it correctly etc), I might be able to start out with the CP deal using the micro and if I like it, then I'll commit to a 50 sized CP(electric).
There's just that huge and steep learning curve between what I'm doing now and trying to go CP and micro size it all in one step.
I'm only doing this(to myself?) because I've already bought the CP and realized too late that I wasn't up to the task just yet.
On the lighter side of things, depending on how things go with the night ranger, it could be a decent learning tool as I've read all over the place that bigger helis are more stable which should keep the price of learning on the larger heli down thanks to the beating I've given the night ranger...but now I'm just getting ahead of myself.

At any rate, I'm digging the making things remotely hover and fly around deal and have my sights set on getting a decent night rig going because it just looks like way too much fun. Perhaps a lofty goal for me, but it should be more attainable than, say, full-on 3D action chock full of piroflipping chaos...because you know that's how it'd have to be.

Nope, I'm not out to really show off or anything...I just like the whole scale, flying around with maybe some banks and nifty turns in the dark with cool little a light show. Kinda reminds me of tron with UFOs or something.

I flew exclusively nitro planks, refusing to get into electric.
If I go to something like a 50 size heli, I would do it to get out of the electric problems.. short flight times, long charge times, etc. WIth nitro, it's just fill & go until you finally drain your radio batteries.

Yeah, there's the nitro mess. But, I put up with it on my planks, I can put up with it on my heli I guess.

Dunno, I'll have to wait & see. Maybe after some time of cleaning a nitro heli, I'll give more thought to electric.

Thanks for the info though. I didn't know there was a straight conversion for them.

Good choice.

Like they say... There's no replacement for displacement... even if its only .499 ci.

Hey 2old2fly, you get the wobble knocked out of that CX/2 yet? I had pretty signifigant wobble from the fist time i spooled mine up.
I replaced the stock lower head and swashplate with the aluminum ones and was stunned at how sloppy the plastic swash was when I got it off. Seeing that I thought for sure I had found the problem, but no it was still there.
I got to looking it over and noticed a pretty good amount of endplay in the inner shaft, so I loosened up the upper hub and while pressing upward on the bottom of the inner shaft seatted the upper hub to the bearing cup and tightened it up. I walked up to it while hovering and the whole shaft assembly was rock steady, even with the plastic bearing cup! hope this helps

A "fixed wing" is just a seized rotor...

Hey Heligun!

Yeah, these things are pretty sloppy from the factory. I've been finding that out. There's a really good reason that they produce the alum. "upgrade" parts.

In my case it was the upper bearing (the little one in the cup). The center hole in it was HUGELY oversized, so the inner shaft was free to wobble around. As it turned out, I could have just replaced the bearing and been fine, but I put the alum upper cup, and the alum lower head assy on, and it made a tremendous difference. The whole shaft is rock stable now.
I think the alum swash plate may be next.

But first, I'm going to order a couple more battery packs, and a decent charger. This 2 hours charging time per battery is killing me!
I have 2 batteries, but it's still like 20-25 minutes of flight time, and 4 hours of charge time.
I'd like to have 4 batteries, and a charger that can charge them at 1c and bring the charge time down to an hour each(?). That would at least help!
So, that's what's next on the budget.

Thanks for writing in on this.
It's interesting to see all the looseness we're digging out of these things.
But once ya get 'em tightend up, and trimmed, they fly nice!
I'm really enjoying mine now.
