Daizey 0 #1 March 20, 2004 Not something I plan on doing just something that came up in a conversation I was having with someone. Perhaps its a dumb question, but I was curious... Say hypothetically a person has an extra reserve. Could they take that and put it into their rig and jump it safely as their main canopy? If so, pros/cons to doing this? I've heard yes it is possible a few times from people, but never heard if its actually a practical and safe thing to do....just curious *daizey* Quote Share this post Link to post Share on other sites
riggerrob 643 #2 March 20, 2004 That used to be common practice back when F-111 Ravens were fashionable as mains: late 1980s. However, after a few dozen jumps, you can no longer pack that main into a reserve container. You see, riggers are downright ANAL about reserve cleanliness, porosity, etc. Quote Share this post Link to post Share on other sites
Daizey 0 #3 March 20, 2004 ok but say you never planned on using it as a reserve again...just as a main.... I guess what im also asking is how a reserve differs from a main...and if buying a reserve and using it as a main is safe and can be done? *daizey* Quote Share this post Link to post Share on other sites

CanuckInUSA 0 #5 March 20, 2004 QuoteI guess what im also asking is how a reserve differs from a main...and if buying a reserve and using it as a main is safe and can be done? Last weekend I made three jumps on a demo PD143R canopy hooked up as a main loaded at about 1.45:1. The first two jumps, I deployed virtually right out of the airplane for some soft yet abrupt openings. But on the last jump, I was forced into a terminal opening. The King Air didn't slow down on jump run and I had to wait to slow down before deploying. I didn't get slammed, but it was a fast somewhat violent opening. My other observations are that the reserve does NOT flare as well as a similarily loaded ZP 7-cell, but I was still able to stand up all three landings. I wouldn't do this full time (jumping a reserve as a main), but it was a good experience which I hope to repeat again several times again this weekend while the demo reserve is still available. But I think once we start jumping reserves as mains, they should continue to be used as a demo only canopy. I don't think I would want to jump one of these demo reserves as my actual reserve. Try not to worry about the things you have no control over Quote Share this post Link to post Share on other sites
riggerrob 643 #6 March 20, 2004 Since 99% of reserves are 7-cells made of F-111 fabric, they fly like CReW canopies. The nearest production canopy is the Triathlon. Albeit, Triathlons open much softer. Compared with modern mains, reserves open harder, glide steeper and have a small "sweet spot" during the landing flare. Fortunately, most of reserves designed in the 1990s (Amigo, PD, R-Max, Smart, Tempo) have larger "sweet spots" that allow them to be loaded more than 1 pound per square foot.

My Lightning actually opens faster than my reserve tho :-) Quote Share this post Link to post Share on other sites
