Issues with 10261 Rollercoaster and Power Functions

Has anyone has issues with trying to get the Creator Rollercoaster 10261 to run smoothly with power functions. Ive built mine and seems to work fairly well manually but once I try connect the M motor it seems to run smoothy a couple of rotations round but then seems to encounter issues. The cars either jolt on the main hill, but the worst issue is the first wheel at the top of the climb. This sometimes seems to cause the car to stick at the top of the climb and almost cause the whole mechanism to stick and creates the most dreadful grinding noises. Ive tried loosening some of the gears, but keep encountering the same issues. As I say its fine manually, but this only seems so obvious when the M motor is connected. Anyone got any fixes?? Its as if the M motor is not poweful enough to run the coaster. 

Also having difficulties with trying to get the mechanism that propels the cars from the station to actually work at all. It moves the cars forward but doesnt seem to have enough power to actually get the cars to the bottom of the climb. 

What am I doing wrong or are these just ‘issues’ with the design? Ive watched videos online and the coaster seems to run as smoothly as anything in these.

    Is it seriously just me that has had these issues??

    I haven't got my Roller Coaster built at the moment but I did suffer the same kind of issues occasionally when first built.  It quite often got stuck at the first wheel as you describe, but I went through all the gearing along the top and made sure it all moved freely and with enough tweaking I eventually cured the problem.  Every so often it did jolt up the hill, but that just seems to happen when the cars don't quite sit on the chain right and I couldn't stop it doing that.
    No, the mechanism to launch it out of the station doesn't work very well does it! To be honest I just used it with the motor and gave it a shove myself to start it!
    The only other issue I found was after having it on display for a while the cars stopped making it all the way round, but that one was easy - I dusted the track!!
    It is a fairly 'delicate' design I think, you have to be very careful how it is put together and you only need something slightly out of position to cause problems.

    My roller coaster was pretty rocky at first. I had to double- and triple-check every gearing assembly to loosen it. 

    When checking for tight connections, pay special attention to the mechanism at the top of the hill where the chain goes down. That downward motion needs to be smooth, and tight against the gear. Otherwise, it can jam and your chain will snap.

    Every section of track needs to be properly attached. I moved it once and things got slightly misaligned and the whole thing kept breaking. 

    The chain needs to stay 100% centred - make sure the chain path is clear and nothing is moving it left or right. Finally, consider adding or removing links in the chain.

    No problems with mine, I have two, but you need to manually put more or less chainlinks in to see what works, if the chain motion is unbalanced the whole thing won't work.

    Strange as it might sound - also make sure the roller coaster is leveled. Even if it looks level it still might not be leveled. Like people have been saying make sure the track and everything else is tight.

    Just bought this set, and it's driving me crazy. From the review videos I've seen online, it seems that the gears should move as smooth as butter, and mine definitely do not. The chain seemed crazy tight, so I added two links so that it wasn't pulling the track apart. I'd hate to have to take the whole thing apart to figure this out, but it looks like that's where I'm at....

    Mine worked well when I built and reviewed it but after being idle for a few months I went to demonstrate it to @Legopants when he visited recently only to find it now makes the most dreadful noises, the chain pulls the ramp apart, the coaster gets stuck when going up and doesn't make it all the way round the circuit.

    So, I guess it needs maintenance of some sort to keep it running smoothly.

    @Huw: have you moved it around? I've experienced that when moving the Coaster around, the tracks might become slightly unstuck along the ramp, causing this. Also, placing it on a uneven surface (even just a baseplate underneath a corner) also causes great havoc.

    (although I do not expect our Magnificent Leader to not have checked this ;))

    I managed to solve my issue etc of the chain getting stuck and the track pieces being ripped up adding a 2x2 piece under each join of the track going up.

    Yes I have moved it and I suspect you are right that the track alignment needs to be checked.
