Question for you guys,

Anyone round these parts used a slingshot bar with an ozone c4?

I recently got my hands on a 9m 2010 c4 but regularly ride fuels ('09 and '11) and have SS bars.

Wondering if there are any issues to resolve besides making the pigtails "agree"

I know both kites claim to run with equal lines, just thought I'd ask in case any of you have done this....

Call Josh at cleanline surf shop in Seaside, Or. He's been riding C4's and could probably help you out. Nice kites...

I think since the C4 is a SLE technically, that you might need a little more throw than your current Fuel bar has. If I may pimp myself out here, I have a 2010 Ozone bar that has been used literally twice. Not twice as in, I used it for 2 seasons twice, but really only twice. I got it just before getting on with F-One and haven't used it since. PM me if your interested. Sorry to hijack.
Anyway, I think you could use the Fuel bar but try it out on a light wind day when you may not need all that depower.

When mixing bars & kites:

1. Check the safety type is compatible. ie: one line, two line, front line, rear line? Total throw available with the safety needs to be sufficient.

2. Total depower available. (bar throw & depower strap combined. ) The bar should have close to the same amount that the stock bar had. Too much depower throw and you risk inversion; too little and you have limited depower.

3. Check that both bars are tuned the same way. ie front and rear lines equal length with bar pulled in and no depower pulled in. The slingy bar is set up for that, I have no idea as to your kite.

4. Bar width should be close to stock.

5. It goes without saying 4 and 5 line setups don't mix....

No reason a modern 5-line bar (with 18" of throw) cannot fly a 4-line kite. I just hook up the 5th line (with an extra 2" extension) to one of the front pigtails, did it all summer going between my SLE and C kites.

If you know what you're doing, sure it can be done. There are certain risks involved though. Anyone who needs to ask what bars can mix with what kites though should never even contemplate such.

Modern kites are much, much safer than those of just a few years ago. As soon as you start venturing outside of factory tested configurations you become a test pilot and forego much of the safety margin built into today's kites. I'm not saying somebody couldn't, or shouldn't, go there. But if you're not willing to flight test your new configuration as rigorously as the factory does theirs, then you're taking an unknown risk each time you ride.

I'd hope that if you're using 5 lines on a 4 line kite you've spent quite a bit of time deploying your safety in varied conditions. You should have forced an inversion to see if the safety still deploys. Multiple kite loops, self rescues, anything to try and get the safety to fail.

With 5-line kite, I leash to 5th line.

With SLE kite, I leash to the below bar depower trim-line.

I initially was switching my leash over to 5th-line to self-land, but then I started using the anchor setup with a log, so don't use the 5th-line for anything with the SLE kite. Hooking it up just saves me taking it on/off each time I switch kites. I know there is a small risk adding an extra unused line on my flying setup, it adds more variables into the equation when something breaks (and I've had things break).

I agree that the recommended setup is best. I just wanted new kiters out there to know that mixing/matching works.

Thanks for the advice y'all.
My thinking is it should be ok.
Bars are just about the same length, and both use single front line flagging, equal line length etc.

The interesting difference is while the ozone bar only allows a certain amount of travel when throwing the bar, the SS bar's capability is basically unlimited.

I guess if the SS bar needed a mod for the c4 it would be something (a stopper) to keep the bar from running up too far, to avoid any risk of kite spins.
I doubt it would spin anyway with tension on just one front line, but I'll be sure I check that....
