pst 0 #1 May 30, 2003 I have heard that a brand new canopy, should be broken in with 10 - 15 hop and pops before taking it terminal. Is this true or is old stories since they now use pre streched lines. Quote Share this post Link to post Share on other sites
nacmacfeegle 0 #2 May 30, 2003 I dunno about not taking it to terminal, but its a good idea to do some high hopnpops to get the feel of the way the new thing flies.-------------------- He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.

jlmiracle 7 #3 May 30, 2003 I have never heard of that. It's recommended to open high to play around with it but I've never heard about doing hop n packs to "break it in".

wmw999 2,452 #4 May 30, 2003 Reserves often have their first opening at terminal. The only reason to do that is to familiarize yourself with the canopy, as far as I'm concerned. If quality control is such that you have to worry about a canopy being OK if dumped at terminal, I'd have to wonder about the canopy.

ThighMan 5 #5 May 30, 2003 I normally do a Hop and Pop to "SET THE LINES" on a new canopy. I don't think it is required, much less for 10 to 15 jumps.Airborne Blue Skies, No Wind Feet and Knees Together Quote Share this post Link to post Share on other sites
marcin 0 #6 May 30, 2003 I was told by Atair to not take to terminal my Impulse on first 1-2 jumps (I dont think I complied), because of the lines. Quote Share this post Link to post Share on other sites

darkwing 5 #9 June 2, 2003 I think it is nuts to suggest that you need 10-15 low speed deployments. As mentioned above, reserves seem to do just fine. I wouldn't bother doing even one. -- Jeff My Skydiving History Quote Share this post Link to post Share on other sites
GroundZero 0 #10 June 2, 2003 10-15 seconds is terminal velocity... All parachutes are designed and manufactured to open at full speed. Go skydive. Chris Quote Share this post Link to post Share on other sites
jeremyneas 0 #11 June 2, 2003 I agree with Thighman, I have always heard that you need to "set the lines" on a brand new canopy. So on your first jump take it subterminal and throw as stable as possible for a clean deployment. I am not a rigger, nor do i make parachutes, so it would be best to contact your parachute manufacturer. I have never heard of a 10-15 jump break in period, just one jump.

Yoshi 0 #13 June 2, 2003 I think what he is talking about is making sure that the brake lines are set correctly, but I could be wrong. I think even opening at terminal that would be fine..I dont really get why any manufacturer would suggest non termi openings for any number of jumps...other than opening high to make sure that the canopy flies right and the the brakes are set correctly. -yoshi_________________________________________ this space for rent.

DJL 235 #14 June 2, 2003 An Ass at my DZ just got his canopy religned and found that his openings sucked. After much prodding he found out that it was religned out of trim so that as it broke in, the openings and flight characteristics would improve, thereby increasing the usefull life of the lines. I'll see if I can dig up the correspondence or have him post it."I encourage all awesome dangerous behavior." - Jeffro Fincher Quote Share this post Link to post Share on other sites
jeremyneas 0 #15 June 3, 2003 Actually, I think it has something to do with the first time you put a major load on new lines. You want them all to set evenly. Lines, the attachment points on the parachute, and so on. In reality, I have just heard this from a number of experienced riggers and maybe it's old school, but it doesn't hurt to do it. Once again, I have no idea of the validity of it. J.Neas Quote Share this post Link to post Share on other sites

Quote Share this post Link to post Share on other sites SFerensak 0 #17 June 3, 2003 I may be wrong, but don't all canopy manufacturers test jump their parachutes before they send them out to customers? So in the case of a new parachute (not a reline) wouldn't the lines already be set from the jumps already put on it or is the manufacturer putting sub-terminal jumps on it as well?

Take your new canopy to terminal on jump number one. This old idea comes from the early days of spectra lines. Some of the early producers of spectra line did not stress/stretch the line and uneven loadings would stretch lines differently. In the earliest days of spectra here, we actually pulled it before installing it on canopies. Today, feel free to take all new canopies to terminal on jump number one.

Many new cars recommend you vary the speed of the engine considerably for the first 100 miles or so i.e. don't just cruise at 70 for an hour. It's for engine breakin. Can't see that applying to canopies though.

Hmm. Where did you hear that? The car I have now doesn't do that, and it gets pretty good gas mileage (~50mpg.) Engine computers have a few specific functions like spark advance, mixture, and WOT control; what gets 'set?'
