Physics Problem with a rope and a helicopter

Link to the a file in question.

I've been trying to work this problem out for a while now to no avail for the past few days.

I'm trying to build a simple helicopter design with something attached to it via a rope.

In the example above I have had to remove all custom sprites and images, so I hope black boxes will suffice for now.

As you can see the rope looks odd and doesn't stick to the helicopter.

Any help you can suggest will be greatly appreciated.

Does no one know how to fix this problem?

Come on guys, please. This has me really stumped, a link or anything to a solution would be ideal.

I don't expect this done for me, just need some advice in the right direction

sorry work and can't try it out for myself, but have you used the joints correctly?

I tried something "similar" what you described (okay, without a heli) but with a rope, would an example of this help you?

I since edited the joints so that they now correctly link together

*Updated the file in drop box*

I'm now just struggling to stop the Magnet (Attached to rope, attached to helicopter) from being able to spin all the way round.

I tried a limited revolute joint but that just seemed to cause the magnet to bug between odd positions that I didn't set.

Thanks for the example, its not far off what I'm hoping to achieve but the hook of your rope is attached to a static object whereas mine is controlled by the player.

Use a limited revolute joint with the lower/upper angles set to -90/90, say. Disable physics collisions between the rope and helicopter/magnet. And use 'apply torque' to rotate the helicopter.

Spot on Ramones, works perfectly.

Need to alter the limitation a little for the perfect effect but I can't thank you enough.

3 days of struggling and in less then 30 seconds I can see it working like a dream.

Can you share the CAPX for who have the same issue see the solution?

I'm talking it because many people is beginning and it can help them a lot.

Sure thing, the link should remain the same as I've just updated the drop box file. Hope that helps TelleS0808.
