Hey there! Sorry it took so long to post my build of the Lepin Roller Coaster 15039. I bought the set from Shenzhen China (see more about that here ) during my vacation to Hong Kong. After the trip I got sick for a couple of weeks and then I got busy with other things and then just took my time on the build.





Anyways, here's the pics. Warning! This is a massive picture dump, so I hope you have some decent internet speed.

















Almost all done with the signage.





A sudden realization, that this thing is huge. It's pretty much occupying my whole build table. Not sure where I'm going to put it after I'm done building it.





A couple of track pieces need to be hoisted in using the Tower crane.





Unfortunately, one of the workers took a tumble, but Emergency services responded right away. Let's hope he makes a full recovery.





This set comes with a ticket booth and a concession stand. After building it the first time, I decided to remove the booths. I mean who eats ice cream and stuff right before you get onto the roller coaster?





















Almost done! Just need to attach the last few pieces of track and hook up the chain.





Big opening day crowds.





Go see the clown to get your tickets.













I moved the height check to the coaster entrance. It was originally near the steps leading up to the waiting platform. I figured by that time you had already bought your tickets for the ride that it would suck if you failed to meet the height requirements. In my build, you would check your height before buying the tickets, to avoid being disappointed. In the above pic, the roller coaster staff (dressed up as a unicorn), would check to make sure you were tall enough to go on the ride. If you pass, she opens the gate to let you in. The brown refuse bin is for patrons to toss out all their food and drink before getting on the roller coaster.

Here's the goods, lots of parts bags and the huge raggedy manual.The sticker sheet looks pretty good, although I haven't applied any of them yet.Just a glance at the manual, the instructions are probably lifted directly from the Lego version.Good assortment of minifigs. The yellow and blue ones have Lepin logo on their back.The popcorn vendor.No wonder it took so long to build the roller coaster, there's only a small crew working on it.This black piece wouldn't fit into the studs, but luckily I had another piece to replace it with.The gears are really problematic on this set. Especially the ones in the middle of the pic, and there's three sets of them. They don't turn very well at all.Same two guys now working on the other side of the roller coaster.Woo! Actually my Lepin coaster cars don't glide so easily on the track.Here's a couple of roller coaster employees showing up for work.All employees have to wear costumes. Here are a couple of them in panda bear outfits. The waiting girl is not impressed.Heard some strange sounds coming from the gears, maintenance crew going to check it out now.Another staff member shows up to help with the crowds. Walkie-talkies let staff give each other help and status. I put in some yellow barriers to direct patrons back out after riding the roller coaster. The old way let too many people sneak back in for free.There you have it, my Lepin roller coaster build. I had to rebuild parts of the roller coaster a couple of times because some parts would fall off, especially the gears under the platform where to get on and off. Some pillars would not stay together so I used longer technic pins through the centers.At this point I can manually crank the driveshaft and it will drive the chain to move the coaster cars up the track, just not smoothly. The wheels at the top turn and help to move the cars along, but I think they are the major source of friction on the drivetrain. In future, I might replace the gears, but for now the Lepin Roller Coaster still makes a nice display model.Thanks for spending the time to look at all the pics!
