skydiverkeith 1 #1 February 8, 2012 Opinions wanted... Is the student CYPRES a better option than the expert when flying an X2 with a Spectre loaded at 1:1? Conventional wisdom would say "no", but rationally, it just seems to make more sense. Am I wrong? and why?Blue skies, Keith Medlock Quote Share this post Link to post Share on other sites
LukeH 0 #2 February 8, 2012 QuoteIs the student CYPRES a better option than the expert when flying an X2 with a Spectre loaded at 1:1? No. Student Cypres is designed for student type mistakes and student type canopies. What attributes of the Student model do you think would benefit someone in a large wingsuit?

Skwrl 56 #6 February 8, 2012 I've got a Xbird and an Sbird, and a Storm that I load about 1:1. I'm not sure I understand your reasoning. I looked up the firing specs on the Airtec website. Quote[The student Cypres] will activate when the rate of descent exceeds 29mph (13m/sec). The activation altitude, however, is split. In the case of rate of descent being equal to that of freefall, the opening altitude is at approx. 750ft, as with Expert Cypres. However, should the rate of descent be lower than that of freefall but still above the limit of 29mph (e.g. with partially opened canopy), then Student Cypres activates when the altitude decreases below 1000 ft AGL. Conversely, for the Expert Cypres: Quote[It] activates when it detects a rate of descent higher than 78 mph (35 m/sec) at an altitude of approx. 750ft above ground level (AGL). Are you saying that you think the Student Cypres might be better for wingsuiting because a wingsuiter might be flying at less than 78 mph (but more than 29 mph) at 750/1000 feet? If so, I don't think I'd call that prudent - even my ginormous Storm can pull turns at greater than 29 mph if I fly it like a retarded monkey; I wouldn't want my AAD popping off unexpected.Skwrl Productions - Wingsuit Photography Northeast Bird School - Chief Logistics Guy and Video Dork Quote Share this post Link to post Share on other sites

Yes, sir. That's exactly what I was thinking. QuoteIf so, I don't think I'd call that prudent - even my ginormous Storm can pull turns at greater than 29 mph if I fly it like a retarded monkey; I wouldn't want my AAD popping off unexpected. That wouldn't be good! It didn't occur to me that a 7 cell so lightly loaded could be flown faster than 29 mph! Are you positive about this?Blue skies, Keith Medlock Quote Share this post Link to post Share on other sites
Skwrl 56 #8 February 8, 2012 QuoteThat wouldn't be good! It didn't occur to me that a 7 cell so lightly loaded could be flown faster than 29 mph! Are you positive about this? Positive? No - I can't say that I've measured it. I overstated that bit - and you're right to call me on that. I believe it goes over 29mph. I know I can definitely build up speed when I toggle whip... I'd have to play with my canopy and some logging altimeters... This might be a good question for the canopy forum. It certainly feels fast, though... The way I think about it, the situation that you're concerned about is a sort of a controlled wingsuit flight into terrain. To be going less than 79mph, I'd imagine you'd need to be at least somewhat in control of the suit. (Although I admit watching some of you twig-like guys makes me wonder whether or not that's true...) That would require the wingsuiter to be flying the wingsuit, not unconscious, not having a medical thing going on, or otherwise not incapacitated. For me, the risk of the "Event that Renders Skwrl Incapable of Pitching" is the main reasons I jump with an AAD. If I can't pitch, I'm probably going faster than 78 mph... I acknowledge that there's always the "I forgot to pull" risk (I'm thinking about the four way that went in on the South Pole), but I deal with that risk in other ways - I have four altimeters on me, two of which make lots of noise... Personally, I don't think controlled flight into the ground is going to be what does me in. [I am now knocking on wood so that none of you clowns gets to post a Nelson Muntz style "HA-Haw" jpeg on my memorial site if I go in that way.] Your results may vary, of course... In any event, before using a student Cypres, I'd want to be 110% sure I can't accidentally get over 29mph under canopy...Skwrl Productions - Wingsuit Photography Northeast Bird School - Chief Logistics Guy and Video Dork Quote Share this post Link to post Share on other sites
BMichaeli 1 #9 February 8, 2012 QuoteThat wouldn't be good! It didn't occur to me that a 7 cell so lightly loaded could be flown faster than 29 mph! Are you positive about this? That is very possible. Just bury a toggle and see for your self. you will spin much faster then 29mph. The difference is that students (nor anyone for that matter) should not be burying a toggle at that low altitude. that statement excludes swooping.

I'd bet you could practically reach that speed on just double fronts. I could be way off, but I'll bet steady state descent is close to 15mph, at least.www.WingsuitPhotos.com Quote Share this post Link to post Share on other sites
shveddy 0 #12 February 9, 2012 I was right above someone who was loaded at about 1.3, not flying like a retarded monkey and I saw his student Cypres fire. He thought that he could get away with a student Cypres at 1.1:1 or so, gained some winter weight and that caused it to fire. So the lesson is to not play with those sorts of margins.

DSE 5 #13 February 9, 2012 Here's a turn. Storm 150, 1:1.3 If you're still able to fly an X2 at the back half of a flight so efficiently that you're below student speeds/altitudes, that's incredibly impressive. Quote Share this post Link to post Share on other sites
Electronaut 0 #14 February 9, 2012 Students have managed to have student models fire even under big dopey lightly loaded student canopies. Moving on... I wasn't there and, hell, it happened before I started skydiving. But look up Steve Harrington's death. His AAD still managed to fire, a Cypres. The incident is in an issue of Parachutist around March or April 2010. As to his build and the suit he flew, I have no idea, others in this thread may know. And on the opposite side of the coin, look up Adrian Nicholas and his death due to a Cypres firing low. Quote Share this post Link to post Share on other sites

LouDiamond 1 #16 February 9, 2012 You are not the first one to think this, there was an actual case of "failure to listen to the advise he was given" several years back that I witnessed first hand. The simple answer is no, do not use student mode. I watched an individual use student mode after the mfgr and I both explained to him that it was not a good idea. The next jump he had a 2 out, one in front of another that he decided he would land. Luckily he was able to land uninjured except for some grass stains on his suit. He was jumping a 7 cell base canopy as a main and was still able to cause his AAD to fire when he turned his canopy. I was about a 1000 ft above him at the time and happened to look down and watch the whole thing happen."It's just skydiving..additional drama is not required" Some people dream about flying, I live my dream SKYMONKEY PUBLISHING Quote Share this post Link to post Share on other sites
