What riders love
  • on the first time, you stall out up-side down and launch backwards! It is the craziest hangtime you will ever experience.
  • The inversion gives some of the most unique and sustained hang time I’ve ever experienced if you sit in the middle and the whip coming in and out of it is unlike anything I can get on another coaster.
  • On the first and third front spike you stall upside down or sideways depending on where you sit which is awesome.
  • Still the launch is punchy and the hang time is pretty wild.
  • Super underrated launch.
  • Launches are powerful.
  • Kind of a one-trick pony, but a really fun one.
  • Great in the middle because you don't miss the backwards spike or the crazy spinny inversions on either side.
  • I was surprised how much I liked this one.

Vs. other coasters at Six Flags Discovery Kingdom

You get good floater air on them.

I’ve enjoyed dozens of rides on it and I love the floater on the back spike in the back row.

@duditon1

You do not get airtime on it and it is just too short for its own good.

Ejector Productions

In terms of smoothness, this coaster is great.

The over-the-shoulder restraints are pretty bad, and combined with a minor rattle, you will definitely feel some discomfort in the upper-body/head region.

But for some reason it was a little rough and headbanging.

thecoasterBOII :)

The only downside is that it runs with one train, making the capacity bad (even though when I went it was pretty much dead and flash had no line.

Ejector Productions

Although the one thing is that if you don’t ride this first thing in the morning, it’s really hard to get on without waiting much.

Regardless, this is probably my favorite shuttle coaster at the park.

Kellen Grady, Captain Coaster review

Fun very unique coaster that does well not feeling repetitive at all with its short track length and back and forth motion.

Shmee, Captain Coaster review

Still the launch is punchy and the hang time is pretty wild.

Caleb H., Captain Coaster review

Of the impulses I’ve done, this is definitely my favorite - very glad to see Six Flags investing in it!

Zachary, review

This has punchy launches and two fun stall out on the back spikes.

Henry Japha, Captain Coaster review

The launches were fairly forceful, and the 45 degree spike provided an interesting bit of hang time, but those were the only positive standouts.
