I ordered a custom Spectre 170 and have put 80 jumps on it. Until recently, the openings had been nice. Recently, after my canopy opens but prior to releasing the brakes, the canopy will fully inflate, but then partially deflate where I have a “falling” sensation, then it will reinflate to “stable” flying. At this point I have not put any input to the canopy. It’s not until after releasing the brakes that it really feels comfortable to be flying under. It will sometimes even "buck" a little until brakes are released. Once brakes are released, the canopy flies, flares, and lands great.
The only thing that has been done to this canopy in it’s 80 jumps is having the brake lines shortened twice, two inches each time, and only from the cat-eye down. Maybe it’s just coincidence, but this problem on openings hadn’t happened until after the second time I had the brake lines shortened.
I’ve never had the sensation of stalling on opening like I have recently been experiencing. What could cause this?
I had two riggers independently measured the control lines from attachment point to cat-eye. They said they were correct according to the spec chart. Everything else looked to be in good shape and the line trim is measured correctly.
I am 5’7 and my exit weight is 180lbs. 300 jumps in a couple years, flew a 190 Pulse before this Spectre 170.
