Well sure, I’d do that if I were you. I’d want one. What sort of power supply is required to make it work and for how long?

Thanks, guys, that’s what I thought and hoped.

I have never had one fail, but I won’t be replacing any of my kevlar harnesses until they either fail or show visible signs of deterioration. Aside from some kind of mechanical damage (ie being cut on some other object),…   Read more»

I have a couple sewn kevlar harnesses that have more than 20 ejection events on them and if I run em through the washing machine, they come out basically looking like new.W

But I like your avitar John. 😉

A combination works for Me.A longer cord has helped the most.Also less ejection charge, or the right amount of charge hashelped a lot also.

For my part, I can say that I have *never* had a zipper. Part of that is because I use a lot of glass tubing (less prone to zipping) and I used L-O-N-G shock cords (though not as long as…   Read more»

I think you are right on target on both counts. I use the long side of the range you mentioned with Kevlar, because really doesn’t have much “give” at all.The other thing to remember when discussing zippers is the width…   Read more»

As a recent victim of said zipper, let me say I’ve done a bit of reading and there is no ‘perfect’ solution… It’s just you against physics. I had a reasonably long harness (~20′), but with an early deploy at…   Read more»

I’m not experienced enough to know the answer to Adrian’s question, but I want to point out that I’ve read that a long shock cord helps lower the risk of zippers. Specifically, I’ve read that a shock cord (when using…   Read more»

I’m planning a dual-deploy setup with a small avionics bay as the coupler between the booster section and the top (main chute) section. I was planning to attach the coupler section permanently to the top section, which will also protect…   Read more»

Oh, thats how the one im working on now is. 8)

A zipper is when deployment occurs at high speed (and sometimes not so high) where the shock cord or recovery harness slams up against the side of the airframe and either splits or rips down through the airframe, Zipperless designs…   Read more»

Scott,Thanks again for towing the trailer! With the weather and your L2, you sure had a lot to deal with.

I’ve towed enough trailers to know… tongue weight is generally 1/3 of total load – our case more like 1/5 or 1/6. You need a beefy vehicle and expect to get crappy gas mileage.WarrenV8 DODGE VAN I already get crapy…   Read more»

cool

Scott, I will be out Saturday with your rocket.Art
