I was bored, so after a two year hiatus I pulled out the knex and got to work.
Two and a half weeks later, this is what I came up with...

Name: (Insert Name Here.)

Height 6.5 red rods.

Length: About 55ft.

Track Style: Arrow Dynamics "Out 'n' Back" hyper.

Elements (In order):
Station
Turnaround
Lifhill/first drop.
Airtime hill.
Slight left curve
Turnaround
MCBR/drop
Slight right curve
Airtime hill
Airtime hill
Helix (downward)
Brake run

Here's a few pictures of the coaster. Because pictures are worth a thousand words. Or at least a few paragraphs.

PS: I know my drops are straight, they're supposed to be like that. (Arrow style yeah!)
PPS: If you see any sharp spots, or warped track, please point it out. I'm actively adjusting this thing to perfection.

Looks great!!

The only spot I see of concern, is the valley before the turn around. It kinda curves, flat, curves. (I know Arrow likes awkward transitions), but it just feels out of place, when I see your other valleys are more consistent in the curve.

Cool layout, but there're a few bad points:

- Arrows DON'T have a straight part before the drop, that's Togo.
- Arrows DON'T have a MCBR
- Please make the supports Arrow-ish.

Move on, it's an epic layout!

^Then it would have to either be a Morgan or a Togo.

This is actually surprisingly good! The helix's shaping looks perfect!

Thank you guys for the comments!
Ickus- I will re-profile that turn today, and see if I can't get it a little bit smoother.
RNB- Point 1: I agree with you on the straight spot on the top of the lift, but that was due more to necessity than anything else. I'll see if it's possible to fix it.
Point 2: Not necessarily. Both desperado and Titan are Arrow hypers with MCBR's.

Point 3: How so? Should I change the low height supports to tubes? If your could elaborate a bit that would be great.

RollerKid500: Thanks! I really am trying to make this coaster as refined as an Arrow can be, and it's great to hear that my effort is not a complete waste...hehe.

I will have more pictures up today. Thank you!

Try using the default yellow ration. It should help the shaking.

I threw together a video for the new ride.
If you have any name suggestions, I'm more than happy to take them!
Thanks for watching!
