Mendez 0 #1 September 13, 2004 Here's one I can't figure out. I'm jumping a Hornrt 190 in a mirage g4 Container..My openings have been honey most of the time, but lately my canopy has been doing some serious nose diving during openings. So: I go to pitch - The canopy begins to inflate as normal - As I look up I see most of the canopy inflated - a coiuple of the front corners are kind of bent inwards and kabam - Huge front/nose dive - corners pan out (Fully Inflate) and canopy stabalizes. It's been happening lately on and off...I haven't done anything different packing wise (Pro-pack, don't roll the nose but I do a slight tuck). I usually pitch belly to earth and stable... Anyone?

riggerrob 643 #2 September 13, 2004 Hee! Hee! So you are experiencing forward surge and closed end cells. Welcome to the good old days! Hee! Hee! First of all, this is not life-threatening, because your Hornet is doing what every ram-air canopy instinctively wants to do. I suspect that your brake lines are too long. First question: how many jumps on that line set? Secondly, can you ask you local rigger to measure the line trim? Does he have access to the Hornet line trim chart on Aerodyne's website? Can you print out a copy for him? The other possible explanation is that the outer A lines have shrunk too much (normal on Spectra suspension lines), and are inhibiting end cell inflation. New Hornets are pretty much even across the A lines, but as they age, you start to notice a difference. By the time you get a 3 inch difference across the A lines, it is time to re-line most canopies. Again, refer to the factory trim chart. Quote Share this post Link to post Share on other sites
Mendez 0 #3 September 13, 2004 Thanks for the insight man, The canopy has about 50 jumps on it...Its brand new. What's the life span on lines? In other words how many jumps until it has to be re-lined? I will definately print up the trim chart and have my rigger look into the brake lines. Thanks Again.
