    Hi All

    Just got my first serious helicopter in the UK and set it up as per the threads I can find and have a bit of issue I need some help with. The controller is a DX6i and I have used the inputs as suggested on this forum but have no control over forward and backward movement. Side to side is fine, lift is fine, tail rotor and gyro work well but i have not real movement front to back. These are the settings I have used as originally posted by Boggy:-

    dx6i settings for the blade ( standard servo's)

    beginers level
    d/r - expo
    pos 0 100% expo as req" (with expo + values numb the controls - values sharpen them)+20% is a good start point for beginers
    pos 1 80% expo as req"

    travel adjust 100% on all exept rudder=90%
    all sub trims 0 (perfect mechanical setup! )

    gyro sw=gyro (these values should be used as starting points and reduced 1% at a time if you get a tail wag,or raised 1% at a time if it drifts)
    pos 0 73%
    pos 1 73%

    normal
    throttle curve .................. or alternate curve
    pos L 0%......................... pos l 0%
    pos 2 60% .................. pos 2 50%
    pos 3 85%.................. pos 3 60%
    pos 4 85%.................. pos 4 85%
    pos h 85% .................. pos 5 100%

    stunt pos L 85%
    pos 2 85%
    pos 3 85%
    pos 4 85%
    pos H 85% you can up these all if you want higher head speed but 85% gives a nice speed for ff figure 8s etc ( will need higher for stall turns loops etc)

    hold 0.5%

    pitch curve
    norm pos L 35%
    pos 2 43%
    pos 3 50%
    pos 4 75%
    pos H 100% this will give lift off about mid way between half/3 quarter stick)

    stunt posL 0%
    pos2 25%
    pos3 50%
    pos4 75%
    posH100%

    hold 35%43%50%75%100%

    swash mix airl -75%
    elv -75%
    pitch +85%

    channel reverse ...(swash mix and channel reverse will need tweeks for those that have replaced servo's)
    thro N
    airl R
    elv N
    rudd R
    gyro N
    pitch N

    swash set to ccpm 120 degree's ( if your going to use these settings for phoenix flight sim also.. start a new model memory copy the settings over and set the swash type to normal 90 degree's 1 servo)
    throttle cut inh
    dr/combi inh
    timer set as req .. switch=throttle cut
    power A-EU 328


    for more advanced pilots the stunt throttle curve can be altered to 100% or made into a "v" curve to your own preference

    for non standard servo's

    the channel reverse and swash mix may be different so to set these up first follow this quick guide.
    set throttle hold or better still disconnect the motor then

    move the throttle stick up and down. all three servo's should move together,as you raise the stick the swash should fall. as you lower it the swash should rise.( if there is a problem go to the reverse menu in the set up list and alter the pitch/airl/elev servo's till they all work together in the same direction.

    now the right stick.
    stand behind the heli.
    each movement of the right stick should move the swash the same. eg forward tilts the swash forward etc. if you have a problem go to the swash mix menu. you will see the 3 values set with either a + or - %
    if the swash tips back instead of forwards change the value of the elev mix to opposite what it is now set at(eg from +60% to -60%)
    if the swash tips right instead of left change the airl value to opposite.
    if the swash tips at an angle when you apply forward stick change the pitch mix value to o

    I haven't read all the way through, but you don't need to fly it to test the fix. The swash should tilt down and the back tilt up with right hand stick moving up, and the opposite with the stick moving down. The stick up and down movements assume the tx is vertical. The servo connected to the centre of the swashplate should be moving one way and the other two moving the other way. The swash itself should stay in the same place. The swash should also be level and stay level as you move the throttle. There's an intermediate arm that connects the front servo to the swash, it must be in the right place. It's on splines. I'll read through again later if you still have problems.

      hi mate thanks for your reply. The swash plate doesn't move very far either forward or backward, however when I manually move the swash plate it seems like their is a potential 75% more movement than the servo uses.

        You really need to setup the helicopter properly using a swash plate leveller and pitch gauge rather than copy someone else's settings that may not be appropriate for your fitment. PM me and I can email you a crib sheet if you'd like.

          A pitch gauge would be a good idea. You should be able to get the same tilt foward and back as left to right. You may have a problem with the front servo, although if you have the swash wouldn't stay level from min to max collective.

          Sometimes the model memories don't tell the truth about the settings, or they can be messed up. It does happen sometimes. The cure is to start a new model memory from scratch.

            Ok all seems much better now after that however when I increase right stick to move the elevator servo it also moves the two aileron servos preventing the swash plate from tilting much. In other words as the swash plate tilts forward the two ailerons servos drop reducing the amount of forward tilt on the swash is this correct before I go have a test fly not sure how to post a video of what's happening otherwise I would let you have a look. As a beginner to larger scale helis I appreciate all your help.

              No it's wrong. You've got an error in your setup. The two servos either side act in the opposite way to the one at the front for elevator. Are you sure the swash stays at the same angle when you use collective (throttle stick). What servos have you got? It's very easy to fix. You just need to change the swash settings or the servo direction. I haven't done this for a while so I'll have to think. You may well have the servos connected to the wrong channels. It isz easy to work it out from first principles.

                Don't worry I took it outside for its first test flight. Small hover 3 feet of the ground then pitches violently to the right. The servo on the right hand side is now just buzzing as though the gear internally aren't meshed at all. Back to eBay for new servos then will take it to someone to set it up. I have spent nearly 3 years on my little Cx2 and am very capable of all aspects of flying that. The hobby shop never even offered me training gear so had to get that myself from somewhere else may I add! They told me it would be ready to fly straight out the box and I only needed to charge the battery so pretty peeved with them and my obvious lack of set up experience. Maybe stick to planks I think lol.

                  Was this a new heli? If they sold you a package ready to fly straight out the box, then you can take it back and get a refund. I started with a Twister Storm and it is cheap and in many ways nasty. There are much better options for learning. CX2 to Twister Storm is not the best move. It is ok if you have looked at all the other options and not liked them. A 450 is very easy to damage and in many ways the worse way to learn. I would have a look at an msr, msr-X, mcpx,or 130-X. They will all survive a fair bit. The ones on the left of the list will survive best and be easiest to fly and the other way round for ability to handle wind.

                  Don't do anything without talking to some heli people and finding a proper model shop. You will enjoy flying the Twister Storm eventually.

                    Hi CJc yes the heli was brand new out the box, unfortunately I bought it about 18 months ago and never built it! So GeeDee have told me its out of warranty when I questioned them yesterday about a slight twitch in the servo which it now turns out has failed. I stripped the servo out and three of the teeth on the main drive are missing. I haven't crashed it even though it did wildly dive to the side this morning it was saved by the training gear. I have ordered a new servo and I'm going to try find someone in Nottingham ( not GeeDee Models) to help me set it up correctly as in all honesty this is like whitch craft. Lol thanks for all your help so far and I will post again when it's fixed. PM me of you know anyone in Nottingham who charges a reasonable fee to setup the Twister that would be handy.

                      You can do it yourself with some help. You don't need a new servo. The gears are available. They are easy to change. The gears don't go unless the servo has been damaged by the arm being pushed back suddenly, usually in a crash. I have some Twister Storm bits and you should be able to get more bits very cheaply or for free if you ask on the forum. Especially the servos. Most of the Twister info that comes with the model is correct. In the setup for the swash there is a sign that needs to be changed. It might be on the elevator. The esc is shown as being mounted the wrong way round (It should be heatsink out not in) and the esc to motor wires should follow the colours and not swapped over as shown.

                      In a 120 degree swash you have three servos and they must be connected up the right way. Two of the servos will move when you use the ailerons. The other servo won't move. The servo that doesn't move will be the one to go on the centre line. The other two servos will go either side of the centre. You then need to adjust the sign of the swash control and the servo directions so that the swash goes up down the same amount as you move the throttle.

                      I've found my Twister Storm info.

                      Your settings are completely different from mine. I used a DX6i and standard servos.

                        Hi CJC1949
                        I have decided to book a setup with build and fly as these settings seem to work better but not 100%, think its more of me having some inexperience issues rather than anything wrong with the heli. I will update you once i have been on 2nd May

                            I had my setup lesson with Jason at Ultimate Build and Fly and cannot highly recommend him enough, That was the best money I have spent on helicopters so far. I now have a stable helicopter and i know slightly more about the Helicopter than I do the surface of the moon. I have had several flights and can confirm that I am now able to hover tail in, facing right and facing left however although I can nose in on the Phoenix I haven't quite plucked up the courage on the real thing yet, may put the skids back on for that one I think.

                            I am now looking at joining a proper club as neither of the local ones I emailed have responded so going to have to maybe look further afield which is a bit pants but i will just keep looking. Think I should have researched local clubs better before getting into the Hobby as they all seem to be 45 mins-hour drive away and alone time is precious as any married man will tell you

                            Thanks all for you words of advice and hopefully one day I will be able to offer my pearls of wisdom to some newcomer to this dark art
