Building a rollercoaster, aka "The Pirate"
Carsten Svendsen posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
**Recovered from the server chrash** As some may have seen in the generals section, I'm building a rollercoaster vehicle with some help from legolijntje Almost obviously, I'm also building a rollercoaster and it's a bit larger than I first thought. (This one) Scale equals 1:28,125 and the complete lenght of the track will become 26,84 metres and 1,78m x 5,69m in dimensions or 10,11 m2 The scale is based on that the original rail have a distance of 90 cm in between, and my track has a distance of 5 studs (or 4 studs, mid-hole to mid-hole) that equals 3,2 cm At this stage I have build a 1,5m long track and I'm not to happy about the results. I think that it's the car that's the problem because the track should be smooth enough. I can't upload a video in this given time because I don't have enough internet left (already used 55Gb this month), so in the next weekend, it will come. However I can show you guys my experiments and findings so far. There are 3 different track parts that I need to make: - A 4-sided track for the first hill including lifting mechanism (3,02m) - A 3-sided track for the middle part of the coaster (15,64m) - A 2-sided track for the last few metres of the coaster (8,18m) I'm not quite sure about the 4-sided track yet but I have build a 3-sided one. This track consist of the following process: + = + Link = It's really flexible: And in full it looks like this: For the 2-sided track I figured I'd just do this as it's easiest and I see no reason why it shouldn't be like that: As it looks now, the car drives really well on straight lines, but as soon as it starts to curve, the car derails. It's because there are no wheels under the track but I will see what I can do about that. I think, that to make the car go all around the track, I need to put in a motor in one of the cars to get it around. Also, the gravity is really weird; IRL the car doesn't come as fast down the hill as the LEGO version does, but then the LEGO version slows down muh faster..... It's a strange world really....
