What size hexagonal or octagonal chute would this be equivalent to?

Thanks!

A 12"-13" 6 sided chute has about the same descent rate...everything else being equal.

Ok,

(and I ask this question out of ignorance)

What would be the advantage of using an x-form chute at nearly twice the cost of a ripstop 12" chute? I'm thinking the "cool factor." :cool:

John,

2 questions:
1) Do you have any pictures of these chutes?

2) Are you planning to offer them in different sizes in the future?

Thanks.

Now I'm no expert when it comes to aerodynamics so anyone can pipe in here but here's my theory. A reg chute while motoring across the sky will create some lift (at some point) due to the nature of it's shape (somewhat like an airfoil) which helps it to drift (staying in the sky longer. The advantage of the X type chute is the lift effect is somewhat disturbed by the shape and thus tends to drift less. So, you use a slightly larger chute to maintain the same decent rate, without the drift. I realy like them for high alt stuff.

I will probably offer a 20" and a 26" (for those 18" and 24" chute models). I will have a photo tomorrow as soon as I get my camera back. COLORS- next will be all orange, all yellow, red/yellow and red. For Halloween, I will be offering a Black/Orange.

Question-

Is the 14" chute equivalent to a 14" hexagonal chute, or does it have more drag or less drag? I may buy one, don't hold me to that though.

Less filling, same great taste....

Actually a 14" inch X chute has probably more drag, and less lift.
