FCX Dual pin reserve hook up?

[cvfd1399 0]

Attached is a drawing of how I saw a dual pin reserve hooked up. It seems to me this is wrong. The puller is only held on the pin by being over the pin, and stopping at the pin/cable connection. With the puller being hooked up to only the first pin that way, if the unit is activated and the puller pulls the first pin out it is then free to slip off the pin b/c the pin can swing out to the side allowing it to fall off before it completely pulls the bottom pin out. Unless the cables are the exact same length, or the bottom pin is shorter allowing it to come out first is the only way this can work. I am not a rigger, but is this right, or should the puller be attached on both pins?

This sort of installation is quite common. The pin spacing is critical; the end pin must clear at the same time or very slightly before the pin where the puller is attached. Pin spacing varies from manufacturer to manufacturer. If your ripcord is not original, checking pin spacing is doubly important.

FXC does not make a 2-pin adapter that pulls parallel with a typical 2-pin ripcord (both pins swaged to the same cable), because they'd need to make adapters for every conceivable pin spacing -- and because there's no need to. Their 2-pin "Y" puller is intended for a 2-pin 2-cable ripcord like one used by a Strong Eagle or Hawk.

Two things to try when the reserve is repacked:
-- When the reserve is finally closed, insert the ripcord pins without taking out the temporary pins. Pull the ripcord slowly, and watch which pin releases first.
-- If you aren't satisfied with the slow ripcord pull test you just tried, finish the pack job with the FXC installed. Fire the FXC using the plastic bag method, and see if the ripcord is pulled the way it needs to be.

I can’t really figure out your drawing, but I think I know what you’re trying to say. With some manufactures that have 2 pin reserves the closing loop is ‘free’ that is you can pull it out if there is nothing stopping it. So if only one ripcord pin releases the closing loop should slip through and release the tension allowing the p/c to launch (in theory).

It might be a "continuous loop" as you stated, that would be another way if only one pin came out it would still deploy the PC. I have never seen the reserve so I don't know.

Can anyone post a few pictures of what a dual pin reserve connection looks like using a FXC 12000.

Sorry, but I do not have photos of FXC 12000 AADs installed on 2-pin reserves.
There are two popular patterns. The first pattern is the same as your first photo.

The second pattern involves a Y shaped cable, involves a larger stiffener and is not half as popular.

Again, a caveat about consulting the container manufacturer's instructions when installing any AAD.

Thanks for all the help. I cannot contact paraflite regarding this rig they do not give advice to civilians regarding de militarized gear. All fcx said was 125$ for recalibrate, and 90 days waiting period. He would not give info on how to install it on this rig, he said to contact paraflite.

Jumpshack may be able to help you out with this. I used to have a jumper with a racerwith an FXC 12000 hook up and it was just as I think you are describing. Remember; the pin spacing is generally set so that if one pin goes, the other will go at the exact same time. To do otherwise could give an uneven launch. Make sure the pin spacing is correct!

I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet.

IIRC, the Para-Flite Swift container had a two-pin reserve. Is your de-mil rig similar? It may be possible to treat your rig like a Swift on steroids, the way a Tandem Vector is basically a very large sport rig.

Ask Para-Flite if they have drawings for an FXC installation on a Swift.

Since Para-Flite never sold any MT-???? harness/containers to civilians, a civilian packing manual was never published. Better to bug one of the military riggers - who posts here - into photocopying the US Army manual for you.
... kind of like when FXC told me to read the United States Air Force manual on an obscure - ejection seat only - AAD. Fortunately a rigger who worked at Edwards Air Froce Base was able to get me a photo copy of the USAF manual.
