QuoteI took my vented Flik293 with a mesh slider out of the Otter at Perris the first few jumps just to get some time under it. While it was not a comfortable opening it didn't damage anything. The second jump the pilot forgot they had a HnP and let me out at 6500'... Well not wanting to be the the air under a 293 with a load coming out in the near fututre I took it down to about 3000' feet before I deployed and it smacked me, but again no damage.
Why on earth would there be? BASE canopies are designed to open at terminal with a mesh slider.
Do you want to have an ideagasm?
My sabre 190 before i made a bigger slider for it was craccking open in 300 feet at 120 it was killing me.
Track high, Pull LOW!!!

Very few ZP canopies are compatible with BASE jumping.
Triathlon 230 is the only one that comes to mind.
Triathlon 260 would be even better, if you could find one. Aerodyne only built a handful of Triathlon 260s.
Then again, Triathlon is really little more than my old Cruiselite 220 updated with modern materials.
Rob, would you jump a 900ft cliff slider up on a Tri 230/260 ? Would you jump a 300ft antenna slider down/off on a Tri 230/260 ?

Only if I was desperate.
I was trying to make the point that most modern ZP canopies are incompatible with buildings, antennas, spans or earth.
Triathlon is one of the few seven-cell ZP canopies.
The only obstacle I would seriously consider jumping - with a large Triathlon - would be a 600 foot bridge with few supporting pillars ... to reduce the risk during an off-heading opening.
Even in that circumstance, I would probably still sew a tail pocket and tail gate onto my large Triathlon.

A vented canopy is designed to open quickly at sub-terminal speeds. While a slider will slow it down as wil a D-Bag and rolling the nose/tail, a vented canopy still opens very quickly. When BASE jumping terminal with the same canopy I use rubberbands on the slider to further slow the openings. However I wanted to know if there wer limitations I should be aware of; either in opening characteristics or performance, so I packed with mild rolling of the tail/nose and no other mechanisms for slowing the opening.
As I mentioned previously it was a spanker, you can here me cussing on the video, but no damage to myself or the equipment. I had more confidence in my gear than I ever did previously even though I had already done a number of BASE jumps before I ever received my new rig.
Also, who knows would you rather the thing came apart at 3000' with a reserve or off a 300' cliff with nothing but rocks to break your fall. It was a good test!

And also to open at terminal speeds with a mesh slider.*

I don't.

I don't use any of those either.
Again, absolutely no reason why it should cause damage, it's what it is made to do.
* With maybe 2 exceptions that I'm aware of.

I was not suggesting that it should do any damage I was just reflecting that it didn't. A couple of others had commented on HnP slider down with a Sabre2 190 and the damage it might cause...
I don't think a sabre2 190 HnP will open any faster than a vented BASE canopy and I don't think the opening shock at 80knts will be anything greater than taking a vented canopy with a mesh slider terminal.
I do think the consistency of opening and heading performance of the Sabre2 will be much worse. I would also think the forward speed of the Sabre2 would be much greater. The high aspect ratio of a BASE specific canopy creates a much larger frontal area which increases resistance to forward movement along with the difference in trim and control line configuration.
I think these things would influence the thought of whether to BASE jump the Sabre2 much more than the opening shock of a ZP canopy without a slider. A hard opening on-heading is much more survivable than an 180, with line twist, a lot of forward speed, and an object staring you in the face.
