3Qs: Hand brake landing, Sticky safety, and Luffing Sami.


Hey guys,

Three separate questions, but I'll do it in one post, save spamming the forum.
I'll also try and keep it as short as possible.

1- The top hat safety on my '08 frenzy is a bit 'sticky' for lack of a better word. I can pull the safety fine, but the pin doesn't actually release until I knock it with my hand. It hasn't been a problem yet, but wanna get it sorted before it does. Is there something I can do to fix this ?

2- Again RE my '08 frenzy I'm wondering about the hand brake strap. I assumed it would be comparable to the brakes on a FB, as in; pull them to back stall and land the kite. but this isn't the case. Pulling the strap powers the kite, just like pulling in the bar.
Is the strap just there for reverse launching the kite ?
At the moment to land the kite I've been using the (sticky) top hat safety release, but I don't imagine its good for the system...

3- RE My Samurai II 5m, which I use on my turbo bar.
The kite luffs constantly. Its so frustrating ! Basicly at the bottom of the sine wave movement, just as the kite is turning back up the bottom end will luff, fold up, and cause the kit to loose the majority of its power. Its only started to do this recently. I've tried fiddling/ trimming with the brakes no end, but cant seem to sort it. I checked the bridles, and line lengths and they're all okay as far as I can tell. There was a little bit of sand inside the kite, but I really don't think it would be enough to cause the problem !
Any ideas on what to check next ??

Thanks
Tim

#1-how much 'pull' is the kite putting on the safety when you are testing the safety release?
i don't have Oz's new CL/system but i have others and they may not release instantaneously-fraction of a milli- second (maybe they really should) under a minimal load. when the kite is well powered the safety sure will pop no problem.
#2-handbrake strap...your right about that the strap. it cups the trailing edge (the bar looks lke it does the same but it moves the draft point further aft...close enough net effect to a point).
are you pulling the brake strap quite extremely (as far as you can) back or just enough to add some power then you say WTF and stop pulling it?
for landing pull it back as far as you can. way further than what you would to reverse launch for instance.
#3-hard to tell from description but maybe you are putting too much input and too quickly..stalling the sail. pulling too hard too fast and too much for the current wind condition(s).
i don't know.

Rev's right, the hat system needs a fair amount of load to work flawlessly. If not enough load the hat gets pulled and the pin sometimes just sits there. A quick hard tg on the center lines will push it through the rest of the release process.

Using the safety to land the kite repeatedly shouldn't produce any unwanted wear on the system or the wing. It's essentially the same effect as grabbing the brake handle.


Speaking of break handle, Rev's right, you have to wholly commit to pulling it in. It may feel like it's resisting and even powered up a little but it you pull it in like you mean it the kite will slowly stall to about 45deg in front of you and then really stall and fall out of the sky.

Bear in mind if you have the kite trimmed out, you have to pull the brake handle eve more.

#2 ... just want to be sure you do have the power lines connected to the center of the bar and the trailing edge lines (brakes) connected to the outsides of the bar. Depower connects total opposite of a fixed bridle on a bar.

Also when using the brake strap to land I recommend letting go of the bar ... reach out with both hands and grab the brake strap on the edges (where the brake strap meets the leader lines ... this will enable you to be able to steer the kite on the way down. If you just grab the center sometimes it could do reverse loops etc on the way down and end up with twists etc in the lines.

very good advice because this is how you will handle most other depowers that do not have Ozone's 'brake/landing' strap. might as well get used to it and again as Dakitez stated you will be in control of the kite as it comes down.

Thanks for the feedback!

The kite was a little underpowered when I was trying it out. I'll double check and make sure everything is clean, and try again when there is a bit more wind.

And I'm not sure how hard I pulled on the strap, I think like you say rev, I pulled it, then backed off pretty quickly cause felt more power. I'll give it some next time :)

To confirm, is the hand brake strap (or just puling on the lines) the standard way to land a depower then ?

Cheers,
Tim

No...like Dakitez said...
you grab the outside (of the bar) lines about as high up as you can and pull back far enough to get the kite movind backwards (stalling in a controlled manner). since you have both a left and right line under your controll you can steer the kite left or right on it's way down.
i believe (i haven't looked in quite sometime) Ozone is still the only foil depower that uses a strap/line accross the brake(trailing edge) lines.
i know on my Ozone there is a loop (or something that resembles a small handle) in the middle of said strap/brake line. i use that (loop) to stake the kite.
