Just bought my son a Blade CX2 for christmas and so far I am disappointed. Here's why.


Did everything the instructions say. It runs but cannot get it to hover in the house with no wind.
First is turned to the left. So I adjusted the screw inside to balance the two rotors. That worked.
But then it would slide to the left so I adjusted what they call alieron trim as far as it would go and it took out some but not all the sliding to the left. Now I try and take off using some alieron control to keep it centered and it wants to go forward. Even if I trim the forward control.

What to do. I have seen these hover beautifully in the store with no effort, Is something wrong with the shaft, the balance?

I bought it for him thinking that he could have some fun without being an expert, now I'm disappointed. Haven't crashed it yet so it's nothing we did.

Please help and please be clear because we are new at this.

Jim,

Sometimes it is difficult to diagnose heli problems over the internet, but it sounds like something is amiss, either with a servo, or an adjustment. Sounds like you may need to adjust the swashplate and/or linkage...

Maybe take it back up to the hobby shop so they can take a look. The CX2 should hover effortlessly, when properly set up, hopefully, they can get you set up, assuming you bought it at a hobby shop?

In the meantime, here's probably MORE than you wanted to know about the little CX2!!!

Good luck, and I'm sure there will be more suggestions coming forward...

I had to take mine to the hobby store for about what you discribe. Nothing broke. They twisted on the servo linkages to level the swashplate and to get the blades tracking. Now, two years later, they seem like minor adjustments, but back then I couldn't figure it out on my own. The adjustments are discussed in the link above by RotoryDoc.

Don't give up, but see if you can find some place to fly that is bigger than in the house. In the house is pretty tight for a newbie with a CX2. A gym, or even a barn is better space for just starting out. In a house, unless you have very big (20x20ft or bigger) rooms you will break a lot of blades and much more.

I had the exact same problem with my CX2 last month......I am brand new to the Heli. arena and was fit to be tied. My local store try selling me the MCX first, but I didn't want such a small Heli. I boxed the CX2 for now and have been having a blast with the MCX. I should have bought this one first, it is so easy and fun inside (when they say it's not for outside flight, they ain't kidding. The wind took mine for about a 75-100 foot straight forward super fast flight :-)

Good luck<br type="_moz" />

I had the same problem with mine when I first got it. It was extremely frustrating, considering how easy I was told it would be to fly. I took it back to the store the next day and they fixed it for me on the spot - the swashplate was seperated.

To all, thanks for the help. No LHS here and so I fixed some of it myself. I got the side drift out, but I could not get enough adjustment on the other linkage to keep it from drifting forward.

But what really irks me is how delicate it is. First flight after I fixed the side drift when it was going forward and I did not have enough control I lower the engine RPM and it landed on grass lawn from about 3 feet up and not hard. Landing gear broke!!!

It's going back to LHS to be fixed and then it's gone.

Thanks for the help, but to me it's just too delicate. Can't deal with it. I thought out of the box it was an easy to control RTF that my son could enjoy. NOT!!!

Going back to my winter toys, my Erevo and my Summitt truck for the winter.

Thanks again

Jim

I'm telling you, try the E-Flite Blade Mcx.......you will love it "right out of the box".

The heli isn't delicate.. Stuff on this heli breaks just like on every heli.. Every pilot crashes and breaks parts that's just part of flying a heli.. Thats why it's soo gratifying when you get good..

You've never broken a part on one of your rc cars? Do you call them delicate?

These helis are not "common sense" that's why I freak out when people think they should get much larger helis as their first.

Their is no way that you adjusted the servo linkages and the heli still wants to go forward... You were likely adjusting it in the wrong direction.. If the heli is going forward you want to make the linkage longer.. DO NOT use the trim on the remote to do this..

As a newb your son needs to work on hovering the heli 3 - 5 ft off the ground infront of him.. What he should be practicing is keeping the tail pointed towards him until he can hover like a pro with the tail pointing in most directions he should not be taking the heli too high or trying to fly it around..

Flying these helis takes practice... The easiest and best coaxial for indoors is the MCX... This heli is really only meant for indoor flying but the CX is really not a good option unless you have a VERY VERY large indoor space.. The heli will get blown around farr too easily outdoors in the lightest wind..

Keep your CX2 and get an mCX. I had the CX2 first like you and had issues like you and was frusrated like you. But I bought the BNF mCX s-300, binded it to my Tx and was very HAPPY! I just now got my CX2 flying right after repairs and Guess What? I DON'T CRASH MY CX2 AS MUCH! And I don't call them crashes, just some blade strikes against the wall or a moderate landing. The first thing I did was upgrade the landing gear and there are blade grips out there that allow the blades to fold which makes them more durable in a blade strike(the grips and blades are an uprade and will not work with stock equipment, however).... I'm getting that next....... The mCX allows you to fly it around the house easily cause it is so small. The CX2 needs a lot of space indoors to get the full potential, ohter wise hovering, a little forwards andbackwards and a little side toside is all you gone get in small spaces (sounds like a dance huh?).

Thanks for the advice. What is the upgrade for the lending gear, I know from my last relatively soft landing that they are weak. Is their someone that makes them out of better material? If so who and where to get it?

Thanks
Jim

I second the week landing gear.  I also second that a CX2 is too big for a house.  I learned to fly mine at work (in a shop) with 20' ceilings in a 50' X 100' area.  It had a hoist/landing pad in one corner.  I would not fly it in anything smaller as you could not do anything with it.  When the furnace kicked on it would blow it around.<div>
</div><div>If you want to fly indoors, and you do because there is no wind, go for the mCX.  It is 1/4 the size and only need's 1/4 the room.  So a 20' X 20' is more then enough to learn.</div>

Hi Jim;

I own both a CX2 & an MCX and love them both. It is kind of frustrating when you open an RTF heli expecting it to fly decently but doesn't. I had a similar experience with my CX2, but I'm not one to give up easily. I studied the heli, printed out the wiki guide noted above, and set forth to make my heli fly. I was able to figure out the control issues with it, and actually wore out the stock motors! I also broke my stock landing gear on a hard landing one summer day. I have been getting my replacement parts from BoomTownHobbies. I have their Extreme 180 motors in my CX2, and I replaced the stock landing gear with the Extreme ultra flex landing gear. The ultra flex landing gear is so tough, it comes with a lifetime warranty!

Here's their web site: http://www.boomtownhobbies.com

Here is the landing gear I use: http://www.boomtownhobbies.com/BoomT...s_p/bth002.htm

Good luck and don't give up!

Well, I finally got this CX2 running well. The Hobby shop agreed that it was screwed up, probably worse than they have seen one. Also the squash plate (I think that's what you call it) was messed up and so was the shaft holding the blades. Since it never hit anything I can only guess that I got a lemon. I also took the opportunity to put the cooling fins on the motors and put the aftermarket landing gear that takes more pounding. It now flys great and hovers right in place.

Before I ship it back to my son I was told about this after market boom that is just a straight rod with horizontal and verticzal stabilizers that replaces the rear plastic fuselage. They say that this boom will make it fly better outside and make it less susceptible to an errant wind that may show up. ( yes I know I can't fly it outside in the wind).

Does anyone have experience with this conversion. Any opinions appreciated.

Thanks
Jim

Hi Authorjim1!! Yeah, I went with that conversion with the CF tail boom and I'm glad I did! One things for sure, it did help my outdoor flying a lot and, to me, it was well worth the money. Personally, I think it looks better also Since I have NEVER posted any pictures on this forum before, but here's some pictures of my bird! I hope it works

Yeah, me again!! Here's some of the improvements I made on the bird; aluminum swashplate, aluminum upper and lower rotor heads, heatsink, non-breakable skids, a carbon fiber outer shaft, and a shorter carbon fiber flybar. I've had this bird for about 2 years now and she still flies as well as the day I bought her. Good Luck with yours

Wonder how your fly times with be adding all that wait?

Well jdphotoguy, your list is pretty extensive! However, in my opinion, I would make a few minor changes. For one thing, the aluminum mainframe and battery holder are really not 'needed' items and the extra weight wouldn't be worth it. As for the motors, they are a good idea, but I would add a heatsink to them. I've been flying stock motors for the last 2 years and haven't had to replace them yet. However, before you go for the high performance motors, you should first learn how to fly the little bird. Again, these are only MY opinions As for the skids...GREAT idea!! Boom kit....GREAT idea because it will help with outside flying. The upper\lower rotor heads and swashplate are virtually indestructable and a good idea. Flybar, you can use the stock flybar, shorten it and put it in a carbon fiber sleeve and you'd be surprized how long it could last. (depending on the severity of the crash, of course!) As for the flybar weights, you can buy little 'collars' at the LHS that would suffice nicely. One other thing you didn't mention was the upper bearing cup. I got an aluminum one and that be a good idea also! I don't know how much help this was, but I hope it gives you some ideas! GOOD LUCK!!!

Thanks BenMer, your comments are exactly the kind of information I was looking for and thanks for spotting my exclusion of the bearing cup, I'll upgrade those as well.
