The patrons have decided that for this month, everyone will have to build a B&M Wing Coaster! These wing coasters, made by the company B&M, have very wide vehicles, which have their seats to the sides of the track! When making a ride like this, it's always fun to make them interact with surrounding scenery. Often these rides have keyhole elements, where it looks like the wide train will just fit through a hole shaped like the vehicle. I recommend checking out some POV videos, like the one from Gatekeeper at Cedar Point. Something you could probably also consider is making a station where it looks like guests are queuing from both sides!
It would be possible to make a wing coaster by having backwards multi-dimension coaster trains, but that is very tricky to do, so for this contest you will be allowed to use the custom B&M Wing Coaster trains! Keep in mind that these vehicles are very light in the game, so you'll probably want to set their mass a bit higher. I have covered this type of coaster in a tutorial which I recommend you to check out!
