I have had my blade cp for about 6 weeks without a successful hover. It keeps wanting to tilt to the left (standing behind heli)not in a tail spin. I have played with the battery positioning, trim and compared controls from left to right with no luck. Question... should it be relatively stable as I am trying to get off the ground or will it be unstable until I get airborne? Frustration.... high
Happy Holidays and thanks in advance.

with the little helies...it will do that...
you have to get at least about 8-12 inches up to get a hover, if you try to hover at an inch, it will tend to roll, as your flying in very unstable air...

I'm having the same problem. I chipped the blades on the first battery so I don't know if
the instablilty is caused by that or by some other reason. Waiting for crash kit to arrive.

My blades chipped after the first few minor tip overs and I repaired them with Packaging tape. As far as blade crack performance, I did see a difference but if your pretty good at hovering then you can handle it but there's nothing like new blades. Now as far as you not being able to hover it, you might want to check and see if everything is in trim. I recieved a Blade CP on xmas and I am totally new HELICOPTERS but I am pretty advanced in airplanes, and now I am able to do very very stable 10ft hovers with my BCP, Like (rjm1982) said, you need to get about 12 inches off the ground in order to achieve a pretty stable hover, when flying under those specs it will tend to move all over the place due to (GROUND EFFECT). Please note I am a total newbie to helicopters also , but my advice is keep practicing and think of the heli's blade as a big PLATE spinning on a needle and your basically trying to keep it stable. So pretty much controlling the main blades is the whole part of hovering a heli. As far as tail movement, I would suggest increasing the GAIN so that the tail is much more stiff and doesn't sway when trying to hover. Read the owners manual, it has some great tips, also check out this website as far as trimming everything out>> www.bladecprepair.com

Thanks for all the feedback guys.... I'm feeling a lot better now knowing I'm not alone. No flying time since my last SOS (working too hard, no time to play) but eager to get going again when I pickup my crash kit from the LHS and try some of your recommendations.
Thank you all and Happy New Year.

I held my heli in my hand and powered it up to see if I could feel it pulling to the left and I learned alot about
what it tries to do when you take off. Mine wants to tilt to the left strongly. I tried idling up pretty high and
experimenting with the right stick and it does not respond equally in all directions. It has a strong tendency to
tilt left. When I tilted to the right full stick I could barely feel it compared to the left. The mechanics seem to
be working correctly so I don't know why it favors the left side, perhaps something is misaligned or needs adjusting.

There is a very good article on balancing the blades in RC Heli magazine, Issue 2. They even use a Blade CP as the demo. Should be on newsstands now.

All helis do this, but with small one it seems worse because the tail push it side ways, when you get up 8 or 10 inches it will be easier to control, get the trainer gear if you think it will tip over,
Make sure that the swash plate is level 90 to main shaft, (UNPLUG MOTORS FIRST)do this with the idle up switch on and stick at center. assuming that you have not changed the blade pitch or servo arm positions, servo arms and linkages should be at 90 angles and blades close to zero pitch. Level swash plate 90 angle to main shaft at this position.
Also note if the Heli spins nose left or right and either correct with rudder stick until you hover it too set the proportional ,
correct the lean with opposite on aileron, viewing from behind, it might also go forward or backward correct, get used to moving the stick in circular motions,

I am getting much better at this now.....finally... here are a few things I have learned.
First of all....read the manual....I did a quick scan over it without really absorbing any of it
in the beginning because I couldn't wait to get flying. There are some things in the manual that are
important.....The tips about adjusting the gains are very helpful.....I found that adjusting mine made
it much easier to control.....also the tip about having the heli on the ground, and still, while connecting the
battery so that it initializes itself properly.....both of these tips are stated clearly in the manual I
just never paid attention at first.
Secondly.....get out in a wide open space to fly. If it is windy outside don't even try it. For me
I think that because I was trying to learn in the garage and on the front driveway with trees above and around and
there were just too many obstacles. I was too concerned about hitting the obstacles that I couldn't relax and fly
like I was able to in the simulator. Fewer distractions around will help you concentrate on keeping
a stable hover, and manuevering around a little bit.....you will have to compensate for even the slightest
breeze and you need room enough to feel comfortable about that.
Lastly, if you have a hard landing.....check the tail blades....it will get tilted off center very easily and
that will greatly affect your ability to control it.....after every hard landing make sure the tail blades are
completely vertical.
Hope this helps some of you....I am on my third set of blades now but I am getting more comfortable
with my ability. I plan to take the training gear off as soon as I make a few more gentle landings...

4 in 1 control unit setup help
duh, I inadvertantly pulled out the lower connector on the right side of the 4 in 1 control unit
Their are 3 possible spots to reinstall and no mention anywhere in the manual, or horizon on which is correct for reinstalation?
Please advise.

Hi i'm new to heli's, I just bought a blade cp last night and am happy to say I have gone thru a set of blades already,, ( probably not somthing to be proud of ) ha oh well I had a ? for all you heli GURU'S .... the flybar paddles, what angle do they sit in relation to eachother, ,, are they supposed to be acting like a prop or should they be level ( no pitch)
#17
I was told at the lhs that the fly bar paddles should be flat and even at neutral...that means throttle at low point (for the blade cp, make sure you aren't in the "3d" mode)....also as a prior helo mechanic in a prior life, keep your trims centered when checking this

Aerial, I was in the same boat as you about a month ago. My heli would go crazy when trying to take off. And me being a beginner I would get nervous and just throttle down. But I eventually got over the fear and just starting giving it enough throttle to get it about a foot off the ground. It isnt till you get about a foot off the ground when the helicopter begins to fly like it is supposed to. If you just keep trying to staying close to the ground the Cp is just going to turn left and right....tilt left and right and do whatever it wants to. Eventually after getting your CP a foot off the ground you will start to become a little more familiar with the control and be able to keep it straight and not tilt one way or the other while trying to take off. Hopefully you have a set of landing gear because they help out much with the learning process. Just be patient....you will get it over time. Like I said I was just like you at first getting frustrated with not being able to hover. And you just have to face reality that you are going to break parts while learning. I went through so many sets of blades at first and now Ive been on the same set of blades for a while. So just hang in there.

I agree with the rest of the people responding, left is normal due to the tail rotor, right may be the fly bar paddle (my input), and yes in ground effect take off will be altered by turbulence
