Any buggiers using a HQ Neo 11 (or other depower foil) for a buggy engine? I have never tried a depower foil and was curious about its buggy performance.

Thanks in advance

Absolutely! I use the 8m and the 11m for the bug depending on the wind. In the right conditions both can be park and ride. 11m works really well in light air.
Check the JIBE gallery, there may be some pix of ACampbell buggying hands-free with the 11m.

ive buggied with arcs and flysurfers.... had a blast... i dont think i would use them in a race, but for solo flying, they are a blast in the right conditions

I've been flying a 7m Pulse in the buggy and it is quickly becoming my favorite kite when conditions are right.

Absatootley. Not just park-and-ride, but park-and-ride-and-have-a-beer stability. My 11m starts working with ease in 6-8 mph and I start running out of de-power for comfort around 18. Much shorter bridle than a flysurfer - won't wrap a line as easy in a luff. Not quite the auto zenith of a Peter Lynn but will sit overhead with an occasional poke and nod.
Sets up, launches and lands like any open-cell foil. Just add a leash to the landing handle for landing high winds.

Any concern of exploding the foil if it hits hard on the ground ?... by accident
I know Flysurfer wings have some kind of security valve, but I don't see any on the Neos...

There is always a concern with blowing a seam on a foil when you auger in. From what I have seen with HQ lately you would almost have to do this on purpose. They have reinforced all of the stress points on their kites, and again you would have to bring straight down in a power dive with purpose. I had my 5.0 beamer take a chunk out of the beach the other, and after inspecting the foil for any damage or the start of seam separation, I didn't find any.

But like I stated at the beginning; there is always a chance.

I crashed an 11 in to the water last weekend, when i got it back in the air, it was very sluggish and had taken on water, re landed and found that the zip that deflates the kite had come undone, must have happened with the pressure of the crash, so a defacto blow out valve i guess, zip it up and off I went.

When HQ was on our beach last September for demo day, the HQ Product Manager Jan Hendrick Junker addressed this. He opened the deflate zipper and reached in to display a thick bit of reinforcement tape sewn into the bottom skin and running from tip tip tip. There are two of these in the kite. They feel that this, along with other reinforcement points throughout the kite, offer some protection from blow-outs.
