    RE: .........

    Hi Markus, could you be a little more specific about the glitch? I would certainly change out the gyro and tail servo. Also I am not that experienced in these matters, but I can tell you that the stock servos are mostly junk. Switch to servos with metals gears for one thing. I did recently. Once you start putting money into these helis it will really anger you if you crash because your plastic gear servo strips out. Also it is dangerous if this happens.
    Disney, and Philly, have a lot of time working on these helis and have helped me out serveral times.
    Check back for their response.
    Safe flying,
    Bryan

    RE: .........

    I found a Youtube clip of this servo glitch looks pretty much the same as my problem. Looks like the most from Esky stock have to be replaced if you start upgrade something in my case Transmitter and ESC it appears to not work very well with stock parts. But looks like I should replace both gyro and servo as you say Bryan.

    RE: .........

    Hi Markus,

    Well, although I have no Belt CP yet, it is on the way though, I can think of a reason.
    It must be a compatibility issue between the new Rx to the Gyro to the servo.

    You can test about by this way:
    1. Unplug all the motor`s wires.
    2. Run the heli as usual and apply rudder stick inputs.
    3. See when this glitch happens. If it is doing it periodically or when about.
    4. Unplug the battery. Keep the motor`s wires disconnected. Unplug the gyro and plug the tail servo directly to the Rx.
    5. Run again the heli and see if now the problem is gone.
    If it is then you have definitely an Rx to gyro compatibility issue.

    Even though you may have a more simpler problem.
    Try centering the tail rotor and then set endpoints to the Transmitter. While you mess with the gyro`s limit.

    Ihope it is simply as that and you find it out soon.

    On the other hand I would never spent so much money for a gyro and a servo. Way too much especially if you`re a beginner just like me.

    My Belt CPV2 and my Belt CP X will be here at Tuesday, Ithink. Ihope I can manage them.

    Have fun,
    Spiros

    RE: .........

    Forgot to say that before you mess with the gyro`s limit adjustment first mark where it is now.
    Also Ihad found a nice video for setting up a Belt CP.
    The part that explains how to set properly the gyro`s limit is in this video, at the end of it.

    [youtube]http://www.youtube.com/watch?v=P4RzgRO1QCU&feature=player_embedded[/youtube]
    Well, it is a CP X video but for gyro`s limit is the same thing.

    Also Iforgot to say that if it is not a gyro`s limit and/or Transmitter endpoint setting and/or a combination of this then it must be a timing compatibility issue between the Rx to the gyro to the servo.
    But first see the DX6i manual if the timing can be set to another value.

    RE: .........

    I had set it up properly through a guide but I checked once again and it seem to be fine but still the glitch. I tested unplug the gyro and plug the tail servo directly to the receiver as you said and it worked properly. So then it looks like a new gyro is the next step and better change to a better tail servo then as well. 

    Thank you Spiros.

    So now I would like to know what you guys thinks about:

      [*]SPEKTRUM DX6I DSMX with the including recover AR6210[*]HXT900/662HXT900 9g / 1.6kg / .12sec Micro Servo (on cyclic)[*]HobbyWingFLYFUN Brushless ESC 40A wBec built-in [*]StockBrushless motor[/list]

      together with:

        [*]Spartan Black Quark MEMS AVCS Gyro[*]Futaba S9257 High Speed Digital Servo (on tail)[/list]

        Something you guys thinks/know would work very well? If not what would you suggest for anything as long as it's head lock gyro and got good hover properties?

        Kind Regards Markus

    RE: .........

    One thing about a good Gyro is that it will last you for years. From helicopter to helicopter. I have an LTG2100T that has been on several helis.
    If you want to learn how to fly better in less time, a good radio and a good servo gyro combination is a must. I have learned this recently after using the stock transmitter,and servos for a long time. If I would have had the money for these things sooner I would have been further ahead in my flying abilities.
    As far as the gyro, servo combination, I am not sure, but you cannot go wrong with the Futaba S9257 servo.
    You might try doing a search for what gyro is the best for that servo.
    Some where back through these posts Philly tells what gyro he uses with his Futaba servo.
    Just start going backwards through these posts until you get to his post on that subject. Or you can try doing a search in the search bar for servo and see if that helps.

    RE: .........

    I think you got a point there Bryan. I have been searching some and Gyro Futaba GY401 seems to be something. Now I have been thinking of S9254 instead it can be bought together with GY401. I searched on google which would be the best and it looks like most of the people recommended the S9254 instead of the S9257. Guess it's just because most of the people probably have bought that package as well as I'm thinking of now.

    I'm very grateful of all help I got from both of you Bryan and Spiros Thank you!

    Greetings Markus

    RE: .........

    You`re welcome Markus.

    Well, just in case check your servos also. One or more may have been damaged and make glitches to the tail servo, or the tail servo itself.
    Ithink you had said that this happens only with the new receiver, but just in case.
    The same can be happen if you have changed the cyclic servos with some other brand, that may interfere with the different brand tail servo - Ithink this can also happen in some rare cases.

    Spiros
    I'm sure it's not the servo already checked . All my servos is stock and now waiting for some new after one of them got damaged. But now after I have decided to buy new gyro and tail servo I decided to move the stock tail servo for the cyclic instead. So today I got new blades and with them I got perfect pitch level and tracking excellent. Got frustrated with the stock blades to get them in pitch level and tracking good so now it feels real good since I'm a beginner and my first heli. So now I'm just waiting for the GY401 and the S9254 to come, will be some long days at work this week.

    I hope you will be fine with your Belt-CP v2 and the CP X but guess you have a lot more experience than me so you probably will be just fine .

    Bryan
    I was looking for a few minutes at the site and looks like there is much to learn for a beginner like me . All kind of the set up on my heli and my transmitter is through guides that I have been following step by step.

    I really hope I will be able to program the GY401 that I'm waiting for but I have already been looking some and seems to be some great guides out there so probably it won't  be any problem

    Hello there!
    My new toys arrived and Ihave them in my hands !
    Now I can join the madness of the Belt CP !

    Now look at them carefully, as they won`t be the same soon.
    a) I will crash them. Cross my fingers I will not but if I will then no worry. Spare parts are already in hand!
    b) I`ll change the color combination. First the tail boom and the skids. And definetely the CPX canopy, to a blue one.

    So... Iwill need some help in the near future.



    I wish good flights,
    Spiros

    haha sounds great

    Always good to have spare parts in hand or you ruin your day and a couple of days waiting and waiting. Well ok you got more then one heli compared to me so I guess you would survive. But hey that's not gonna happen

    Sounds like it could be some real good looking helis, when you are finished with your project and if you don't mind you could always upload a picture would be awesome to see.

    Happy flying,
    Markus

    Markus,
    HobbyKing has a clone Futaba S9257 that has been working flawlessly for me, combined with a HobbyWing clone GY520. The gyro costs about $20.00 and the servo is dirt cheap as well.
    I have the real stuff on my Belt, and the clones on my HK450. They both perform about equally.

    RE: .........

    Hi Markus,
    Thank you!
    Well, I have some different color parts.
    Blue: tail boom, skid pipes, tail blades, and I`ll get some paddles.
    White: tail blades, paddles, fin set, skids (450, if they can fit, Ithink not).
    Some carbon fibre fin sets, that Imay not use at all. Idon`t really like CF.
    Some other color parts that are not worthy.

    But Ithink the photo will take a long time to be up. As I will try to use (waste in crashes) all the green parts I don`t want and then fit the blue or white ones.
    What I have in mind is the V2 with green canopy, blue tail boom and skid pipes, and all other green.
    The CPX with a blue canopy, blue tail boom, silver skid pipes (as I have plenty of them), blue tail blades, white fin set and white skids. Paddles either white or blue but Ithink it will be white.
    Also there will be a 450 V2 rotor head in blue.



    Hi Bryan,
    Nice blades there!
    Are they a direct fit or do they need a mod like a shim, spacer, drilling or something else?
    Thanks for the tip.


    Good flights,

    THe blades fly great, very responcive.

    They do require a pair of 1mm shims on each blade. Otherwise they are a direct fit

    Spiros:
    Ah of course, you're right about that. I have decided to go that path as well as long as I'm feeling I haven't full control.
    The blue rotor head you are talking about I guess it's those in metal right? How should they be compared to the stock? I think I have heard being some kind of glitches with them installed but I'm not sure. Something you know about or have some experience of? I would like to have, been thinking of getting one later.

    One thing I have been able to buy recently is a good battery charger. It charges in almost half the time and you can watch each cell to see that it is getting the correct charge. It also allows me see how far down the charge has gotten after each flight so that I don't fly longer than I should on any one battery. You gotta love that!

    RE: .........

    Hi again Markus,
    Well, as for the rotor head.
    Yes, Ibought a blue metal (clone) of T-Rex 450 V2 rotor head.
    Obviously I have not fitted it and more enough I don`t know if it is better to the flight performance and/or to the damage in case of a crash. Neither if it is cheaper to repair.
    But after some searching in the net I found that many have fitted one. Some say it is better to the flight performance, some find it be indifferent to the stock. But they may have not set it perfectly - you can`t know.
    Some have problems to install it properly (does not fit well), some do not. I think the thing that no clone is the same makes a difference too. The skills also do play a role here.

    Well what Ican is to let you know why Idid bought one.
    1. I would need some spare parts for the stock one anyway. So I found it "cheap" enough to worry if it is just a waste.
    2. Ilike the color. It is not a big deal if the flight performance is worse, but it is a big advantage (for me) if it is the same or better. The birds will not fly all the time. Most of it will decorate my house.
    3. Some say it is easier to fine tune (as it is the CPXrotor head). Well, I think the Belt-CPV2 head is "easy" to fine tune as long as you have get used to it. Time will tell.
    4. I want to see which will cost me less to maintain. The stock head (either V2 or CPX) or the 450V2 head. And which will need less repairing time.
    5. Why not? Trial and error for just a few euro.

    In addition to the rotor head, that comes with a 450V2 shaft, I took a King2 shaft as they say it better for the conversion.

    Now there is also another important thing that you can`t just take an advice and go for it.
    It is the preference of the individuals.
    Some find better a main gear that does not wear out in a crash. Well, I think it is better to wear out than the damage goes to more parts. Though I took also a Blade400 main gear to have in hands so to make my own decision/judgement.
    Some find better to have a rotor head that does not explode in parts in a crash but I think it is not the best thing. Time will tell.

    Sorry I saw this late. But the 9254 servo is a standard size servo and you will have CoG issues. The 9257 was the way to go. you'll have to add weight to the nose of the heli and move the battery way foward. You may even have to buy a 2200 battery to help. the 401 gyro is already heavy. I have that gyro on two of my belt CP's (day and night). with the 401 and 9257 I still had Cog Issues. CoG issues especially backward is dangerous. Please make sure your heli is balanced. Hopefully you don't havemuch of an issueas you don't have the upgraded tail. I use the 9254 in my 550 hurricane.

    RE: .........

    In my humble opinion, I have found it to be better to have the metal head. There are less parts to break in a crash. You may however bend the main shaft. Just don't get the pink stuff that you see on Ebay. The pink metal that they use is very soft and tends to strip out. I have what I think is a Trex knock off from Xheli on mine and have had good luck with it. The only thing about Xheli is that sometimes they run out of product and don't tell you and you have to wait until it's back in stock.
    I have ordered stuff from them recently and got it in a fair amount of time.
    Spiros, you will find that the blade 400 main gear will hold up better in a crash. If you crash hard enough though it will strip out thus saving any important parts. Also the one way bearing in the V 1 that I had was hard to replace.
    I went with a trex tail assembly because anything else had failed on me. I got tired of fixing things just to crash and have to fix them again.
    As I mentioned in an earlier post I finally switched to metal gear servos because I have had several Esky servos strip on me while in flight. Not only costly, but dangerous.
    I agree with Philly about the standard size servo for the tail being a little heavy, buy I have off set the weight of mine with a small fishing weight attached in the front of the canopy with  double sided tape.
    Speaking of canopies, if you look around enough on some of the heli web sites you can find some very nice fiber glass ones for very reasonable prices. I think I got 2 from hongkong and paid like 5.00 each for them. They have small imperfections in the paint but who can tell when you are worried about not crashing! LOL!
    I hope this helps,
    Bryan

    I'm running an 11T pinion on the Belt and a 10T on the HK, but the HK has a much bigger motor.
    I'm using 1800 and 2200 20C Turnigy batteries right now.

    Joaquin
    Thanks Joaquin.
