Most drivers leave their Isaac systems in the car all year, but a few are constantly moving them. A pin like this is either of no use, or a "gotta have" item.
What do you think? Is it worth offering?

Nice to have, not need to have (i.e. under $50 for me). I'm kind of with Mark on this one, a cotter pin should be fine as it's rarely under any direct load. As long as you have postive lock, it should be fine ... no?

I understand why one would be ill-advised to replace any other parts of the ISAAC system and I wasn't proprosing replacement of the black pin that goes goes under the belt.

I was not clear. Sorry.
The clips you are using are fine. That is virtually a zero-load application, so most anything will work. We used similar clips for the first few months of production, but had problems so we made the switch.
BTW, I'm pretty happy with my ISAAC system. However, now that certification is becoming probable in our sanctioning bodies, are you going to try to certify your system?
Thanks,
Mark

It might make more sense to offer something like that clip posted above as a standard item. Not as impressive a component as the mil spec QR pin, but for the occasional user it makes a lot of sense. Hmm.
Tell you what Larry, if the QR pin makes the sale we'll get you an Isaac system with wall-to-wall QRpins--price TBD.

Greg, I like that " Retro-Certification for those of us that already them![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)
By the way, I wacked a concrete wall
w/ my drivers side rear quarter @ the Sebring PCA Club Race, and ruined the rear wheel and Snapped the swing arm. Does this "Hit" require that I send it back for a "check-up"?

Is there any difference between HANS and Isaac using them on an open face helmet?
I am aware of the debate on safety on open face helmet on this board. Still have a pretty new MAG5 Snell 2000 helmte, I would hate to replace. But I would like the additional safety of a H&N protection system.

GBaker,
Hi. HANS is making a point of its ability to control the head position on the "whip back" in a frontal crash too. They show in time lapse photos the whip back head postion to be almost level in the fore aft plane vs allowing the head to move in the bellybutton to "looking at the sky" arc. Further thay make a point about the HANS ability to assist in the maintenance of the helmet in the correct position on your head. They make a point about these issues being an issue that sewing machine devices cannot address. How does the Isaac address this issue and is it important? Or is this HANS hype? I assume keeping your head on is the primary goal but the crash is very violent are their other dimensions we need to be concerned about?

The obvious arguments about the advisability of wearing an open vs. full-face asside, what makes an open-face any different from a full when limited to just the H&N displacement/deceleration issues?

That said, I just picked up the latest copy of Racecar Engineering last night and there is a short news item about the HANS and its use in rallying. There was a photo of a driver in an open face helmet with a HANS. So, perhaps Hubbard-Downing has changed their position. Or perhaps they have made some modifications to suit an open face helmet better. I don't know the answer to that one.
I'm sure Gregg can give you his position and if you call H-D I'm sure they will be happy to give you their lastest info/position.

Then again, they are driving full bore around cliffs and the such, maybe the HANS is superfluous
