Kingda Ka Top Hat Fins

Now I'm not sure if TTD also has these but I'm wondering what these fins are for?

Possibly trims to help control speed of the train coming back down the hill.

They are on the "down side" on the top hat. They are there to reduce the chance of a Roll-Back. TTD don't have them which makes it more prone to roll-backs.

How?
By launching the train a little faster than needed, then these trims re-move that extra speed so that the train don't go too fast on the downward spiral...

I love rollbacks. Got one on TTD and it was awesome.

But that does make sense, Thanks!

I do 100% agree with loefet but maybe the're like holding brakes on B&M diving machines?
Just a thought.

^^ If you have ever seen a single video of Kingda Ka you would know they aren't holding brakes.

They're magnetic brakes, so they can't hold a train. Basically magnetic brakes exert a braking force on a train that is proportional to the speed of the train (so the faster the train's going, the harder the brakes). So if the train's not moving, it can still roll freely, so couldn't be held on an incline.
