Rory here. Part of the Chicken Release team.
Going to reply to Hernan's post.
"First I have some complains on your system.
"Gives a reliable and consistent position for the release mechanism to the rider."
It seems to me that the release (velcro gripped ball) could spin with the loop so its relative position to the rider change from right to left, from up to down. I agree that usually you could fix that and when the loop is under tension is more like one line than two."
We thought about this. Didn't have a better solution so tested the device as it is.
Doing this with the ball attached to a center line with and without a chicken loop we have never managed to get it to twist away from pretty much exactly the same area / position. Perhaps if the line wasn't under tension it could move, but if it's not under tension, the won't be an immediate need to activate the kite release.
"Another potencial problem could be the safety line tangling with the ball."
Not thought of this, but have also not encountered it. Although to be fair have mostly tested it with a release line that goes to a back line and so to the side of the bar, not straight up past the middle of the bar and therefore the ball.
It is safer to mount the wichard looking to the spreader hook. This puts the release line in a real fixed position. Other benefit is that you have to pull the release line out and not "in". This setup is wildly used and proved to works fine, mostly by non leash users."
Attaching it to the hook means the whole assembly moves away from the rider, so their depower distance starts further away from their body, which gives problems at max depower. ie you really have to lean / bend your body at the waist, towards the kite. That is the main reason we went for moving the shackle back towards the bar. Also some hooks vary, so a system that could be retrofit to all hooks is not as easy to design. Also we believe you should always ride with a safety line.
"The problem is where to attach the leash? "
Our system lets the leash be attached above the swivel point so that you can do spins .... The safety line / leash has a split pin release if you want to detach from that as well.
"You could not attach it to the swiveling eye of the shalcke because it will be gone after release. So?
Part of the solution is the "two QRs in line". The first QR lets go the bar. The second QR (closer to harness) lets go the whole thing (bar and leash). This way you could attach the leash to the swiveling eye of the second (wichard) release and have the whole system (bar & leash) rotate as a unit."
One problem with 2 Wichard shackles is cost.
It's the highest cost item in the device and 2 means ..... We have looked @ what you say, but couldn't see any added value.
The Second part of the system is the firts or "primary" QR. This one has to:
1- be non rotating (to not change the relationship between the leash attachment and the depower line)
2- be symetrical (to give a consistent position of the release in relationship with the rider)
3- release under full pressure
I have found that a well executed pin and tube release (stronger than the wipi pin&velcro leash release)
have this caracteristics.
- Yes, but where do you attach a safety line / release for still having the kite attached but de-powered ?
Another benefit is that you could detach the whole system in one move (bar & leash). It is not very conmon but I like to have the option (tangled with a motorboat, leashed line broken, etc.)
- hence our folded over pin release on the safety line.
I hope you understand this explanation (my english is limited).
- hopefully I have. Thanks.
I will send you a pic of the system if you want."
