riggerrob 643 #1 October 18, 2005 How long do your tandem mains last? I remember F-111 tandem mains lasting about 2 line sets (600 jumps) in the Southern California desert. Now we have a 1200+ SET 400 in Pitt Meadows. It has been through 3 or four line sets and only now is flare performance starting to suffer. I realize that canopies landed on grass last far longer than canopies landed in salty desert soil. We also know that F-111 canopies are useless after a thousand jumps, but what about hybrid or all ZP canopies? Quote Share this post Link to post Share on other sites
RMURRAY 1 #2 October 18, 2005 I am not a TM but am interested, which tandem mains are hybrid, which ones are all ZP, which ones are all F111? rm Quote Share this post Link to post Share on other sites

skydiverton 0 #4 October 19, 2005 A SET400 is a licence built BT80 (Notice the triple end-cels) If the SET is like the BT80 100% ZePo it can last very long. ++++++++++++++++++++++++++++++++++++++++++++ Using your droque to gain stability is a bad habit, Especially when you are jumping a sport rig Quote Share this post Link to post Share on other sites
camamel 0 #5 October 19, 2005 I start dooing tandem in 85. Back then a 360 main (Hi lifter) was probably not as good, even on his first landing, as a Sygma 370 full zero P even after 2000 jumps. I think roughly that F 111 main are good for 1000 jumps. Zero P top skin main like the PD EZ 384 are good for 1500 jumps, and a full zero P canopy like PD Sygma 370 should last 2000 jumps. Even lines and control lines are more durable now than 5 years ago.Those numbers are good if you jump in a regular environement. The tripple S ( sand, salt & sun) can lower those numbers.When you think you're good...this is when you become dangerous. Quote Share this post Link to post Share on other sites

All tandem reserves are still only F-111. EZ-384 is hybred. SET-400 has F-111 ribs, but ZP top and bottom skins Firebolts have ZP top skins, but the rest is F-111 Quote Share this post Link to post Share on other sites
