i posted yesterday but didnt get any responses yet but i ve played with more now
my problem is every time i try to lift off my blade cp it trys to flip over to the right even when i try to counter react to it .or i react too much and i goes to the left too much . im still not 100 % sure if its me or the heli so i took it apart and put the servo arms all the way to the inside hole much less responsive but still the same thing i have leveled the swash plate i dont think its that
now this morning i was running it in my hand and when i bring it up to speed you can see the blade rocking all around by itself (the swash plate isnt moving) with it off if you hold the gear you can rock the fly bar back and forth a little bit is this normal?ps this heli has never flown two diffrent newbies couldnt fly it then i traded my cx for it .yes i do have a simulator

A couple of things come to mind. If this has had a few or even one whack into the ground there is a reasonable chance the mainshaft is bent. The other often damaged part are the blades themselves. Both need to be corrected to get the balance and running true issuses out of the picture. Then comes the torgue to the right issue. This is to me largely an issue of getting used to what the forces of the moving surfaces do, where to look at how those forces are acting and how to get used to controlling them. For my learning curve, which has included alot of rebuilding, I found the Radd teaching doesn't require air under the heli for most of the basic lessons. Air =Altitude =$'s and complexities of repair. When you are ready, then it flies with much more control and understanding. This said, I have come out of 14+ years in fixed wing R/C including as an instructor for a number of years. Good luck, let us all know how you do. And one more dollar and frustration saving tip that you didn't ask for, put mini fuses in line and save your 4 in 1 from getting fried, Doc

i believe this heli has had a hard life before me and the main shaft was bent when i got it but i replaced it the blades were also damaged but i replaced them and since damaged them because everytime i lift off it leans and hits them could it be play in the upper portion of the head doing this?like i said when i spin it up in my hand you can watch the blades tilt around almost as if someone was controlling it alittle bit but the swash plate isnt moving if this isnt normal i think it might be contributing to my problem .as far as i understand it is normal to tilt to the left but this is severe (i think)

Unplug both the main motor and the tail motor. Then plug up your battery and check to see if the servos are working right. Move cylic forward and aft, as well as left and right. Also push the throttle lever up and see if all servos travel down the same amount. Sounds to me that one or more of your servo's may be damaged.

If you go to the e-flite site they have a pdf of the manual. Also just my .02 cents, I am a newbie also. I just got to the point that I can hover a pack. What your experiencing is normal. I thought for sure my heli was defective. You you can take it to the lhs and have someone else fly it. That will confirm weather it's you or the heli. Once you get confirmation that the heli. is ok you will know that it's you. I had the same problem. Once you stop it from tipping it will slide to the left, once you stop that the tail will rotate. I read a post one day that put it all in perspective "One day you can't do, then the next you can't not do it" Once it clicks it will seem so easy. At least read the RADDS to get a since of how to practice. My main advice is to learn to controll the tail (keeo it pointed at you). It make a word of difference. Get it light on the skids and learn to slide it across the floor at will. Sounds crazy and not much fun but it works. Hope this helps. Keep at it.

thanks for all your help . fxman i dont like your anwser cause its what i feared the most
deep down inside i think its me too i just wanted to make sure this wasnt some common problem . i have read the radds and really thats all ive done through a bunch of batteries cause when i actually fly it i just crash. the cx i traded for it makes it seem so easy though i had no misconceptions

Like I said keep at it. my wife and I laugh at how 2 weeks ago I couldn't get it off the floor without breaking something. Are you practicing is a small space. I practiced in my home office. I had about 6x8 feet to work with. I also have a few wall patches to paint
My first real hover came when I went out to my garage. By practicing in such a small delicate area the garage seemed like a gym. Another tip to try is see if you can set your corrections before you throttle up. I learned where the right stick needed to be for a fairly level take off and worked on setting it there before throttling up. Are you trying to compensate for the left slide by setting the trim to the right? I found that just made my heli. tip to the right.

If you want to confirm that your helicopter is set up right mechanically I posted a detailed setup instruction in a nutshell on the main BCPP thread here:
http://www.rcuniverse.com/forum/fb.asp?m=5099530
This applies to the BCPP but the BCP is similar, it just doesn't (usually) have the Bell-Hiller mixers.
Once you have determined that the head is set up right, then apply RADD's religiously.
Here's what hovering a helicopter is like: shape your right hand like you're holding a can of pop. Now put a sheet of glass on top of the circle formed by your thumb and forefinger. Place a marble on the sheet of glass. Now walk around the room, keeping the marble centered on the glass, while alternately rubbing your belly and patting your head with your left hand.
And if the CX is like a tricycle, the Blade CP/CPPro is like a 10-speed Italian racing bike.
Don't be surprised if it's difficult, but keep after it and you'll get it.

Oh yeah I'd suggest you put the servo links back into the outer center holes of the servo arms. You will need the responsiveness this gives, and there are other ways to "gentle" the heli. The first one to try is to add flybar weights. But first make sure it is set up right and that the servos are working properly. You are using the stock transmitter? Since you are an experienced RCer I thought you might be trying to use another TX...
Oh yeah #2
the blade rocking while you hold it--this is probably the feathering spindle rocking in the dampers where it goes thru the orings in the main hub. It's normal as long as it's normal--I mean there should be a certain amount of this rocking. On mine, when the blades are lined up fore-and-aft along the boom, I can rock them at least an inch up and down at the tips before the main mast starts to flex. This is normal.
The flybar rocking--all this stuff in the head must be almost ridiculously free to move. It took me a long time to understand how it could possibly work with everything flapping around like that. I still don't fully get it. Without seeing a video I couldn't tell you if what you are describing is normal. The flybar rocks everywhichaway, and if it is binding anywhere the thing won't work.
The flybar paddles must be exactly balanced and parallel to each other and to the flybar control frame so that they track evenly, or the heli will shake and wobble.

i am using the stock tx although i have an older futaba 7uaps i was considering on using although from reading these posts it almost seems like too much trouble for gains i might not even notice since ive never actually flown a cp. i have already moved back out to the outer holes on the servo arms .i didnt really see a problem with the limited travel but the reponse was too severly decreased. i also went to my lhs and checked out a new cp and it had just as much play in the head so mine is normal. and yes fxman im practicing in a very small room (my kitchen)as its already dark when i get home from work i only have the weekends to play out side.im thinking about getting those plastic blades cause i just ruined my fourth set of wooden ones about five minutes before this post. i think that covers everything . i thought i had pretty fine motor skills until this curse entered my life now i wondered how i can even get a spoon in my mouth without dumping my breakfast all over my self

Uhh, yeah,,OK. It is possible that the kitchen space is just too small. Imagine a bubble of air, with the heli at the center, about 2 or 2 and a half times as big as the rotor disk. The air is swirling around in there pretty good. I experimented in a small kitchen with a Blade CX and could just barely hover it in there, and I know it would be disaster with the BCPP.
You don't need much more room, but a bit. I'd say 8x10 clear area is about minimum, just because of that swirling bubble of air.
Radd's, Radd's, Radd's.
Now the heli is an "eCCPM" helicopter which means the 3 servos that work the swashplate are mixed in the transmitter to give the correct motion. So if you can program your Futaba for heli eCCPM mix, you can use it, but I'm unfamiliar with that radio so I dont' know for sure. I'm using a SPektrum DX6 in mine.
And you can fix the wooden blades pretty easily, I've gotten many crashes, er, flights out of mine before they are too ugly to fly anymore.

i have never tried programing it for a heli but i was considering it because it has a spot (i guess youd call it a base program for helis ) so i assume it would work i would just have to read up on it but i dont think ill do it until i can fly it on the stock tx so at least then i could appreciate the diffrence. when i said the kitchen im basically just light on the skids i dont actually lift off in the house . i usually practice doing that and then on weekends i go outside ( after flying my planes cause that is my first passion wich is why i thought i would do better with helis seeing i have alot of other stick time)i will be getting the cx2 though because it was just fun being able to fly in the house. although ill wait a bit judging from these threads there seems to be some motor or gear problems cropping up. any way thanks. i just ordered the plastiblades . ps i did repair the wooden ones many times this time i split it right up to the holders. pps one last question my lhs has an mx400 they have had forever and i think i can get a good deal on it (75$) i might pick it up for the future any thoughts on this heli
