I would think that part of it is the frames. The standard Next would transfer more of the input into motion. The UL framed Team Next would flex more and generate less drive from the same input.
My standard and UL Widow Makers are like that. The standard almost rotates around the lower spreader. The UL does big loops. Just the opposite of the Vendettas. The UL does tighter pitch moves than the standard.

From your shots, the Team Next looks to have a shorter bridle (though it could just be the perspective), maybe that's the difference.

My Next Team LW is the Icone version \:D/ . I don't think it loses too much to the SkyShark-equipped Next. There's no sense of it flexing too much. Low overall mass may be the issue but I doubt rigidity is.

I may edit the video I have and post it. Then again... I may not :P

Re: Yoyos - the ways kites do them

Having recently snagged Andy Phelp's old Next Team Light (daylight robbery :-D ) I'd like to discuss the two paths that kites seem to be able to take in performing a Yoyo. Dunno if I actually have a point with this but it's been something that's been bothering me all week. :P

Exhibit A is the original Next, standard wind range:
Image
It rotates about a point close to the kite itself and the whole kite spins about. It's quick, tight and the lines hook up to the stoppers reliably.

Exhibit B is the Team version, for light winds:
Image
Try as I might (and I have been trying) all I get out of it is a wholly different experience. The centre of rotation is waaaaay distant from the kite and the trajectory is a wide arc that it glides around. It takes a good long time, takes plenty of room and is an absolute pig to reliably hit the stoppers as the lines have plenty of room and time to get lost.

The same sort of thing can be seen with the QPro - fitted with no weight it's solidly in Group B, slap in the (optional) weight kit and it joins in with the far preferable Group A. Of course other stuff gets messed up in the process but that's why it's an option. Is it merely a question of overall mass ? Mass distribution (the Team Light is tail weighted) ? Pixies ?
Mike.


Now Im really confused.

Are those arrows pointing the right way? Does the kite nose rotate away from the flier in a yoyo? Ive been doing it the other way :oops: Rotate nose towards me then unwind in the direction of those red arrows!

You're welcome :-D

Let us all "enjoy" a short video clip to thoroughly depict what's actually going on. (.WMV, 1280x720, 50fps, 7seconds, 4.12Mb)

As far as I can make out :? the real difference is once the kites have fully flipped over 180°. From there the Next tucks under and completes the Yoyo but the Next Team sort of glides on, taking its good time and space. I think that if I persevere I'll get it but it's a major pain at the moment.

The reason ? I'm leaning towards aero. drag overcoming inertia in the lighter kite but I'm prepared to be convinced otherwise.

Mike.

Great vid. No other comments, though. The difference does seem pretty subtle, at least in a yoyo take off.

Enough to be a pain :evil: . Believe me, my success rate with the Next Team is pitiful, with the Next it's automatic (SET Tempt Fate = ON)

It seems like the lighter kite is just running out of steam part way through the move. I may try a suggestion of a hint of a soupçon more weight or one of the multiple other bridles that exist to see if this helps.

Thanks, the slow mo video does make it very clear indeed. All this time I thought Id been doing yo yo's Ive been doing something else entirely, a reverse yo yo. I guess thats what happens when you fly in isolation!

Hmmm, I thought nose rotating away from me was a back flip or something, ahh well you live and learn, all good fun :shock: Think I need help!

Either way is still a Yoyo. Backflip (via a Turtle) is what you see in the photos and videos. If the kite is upright (as in the photos) and pulled forwards to wrap up then you are doing something usually considered more difficult.

I hate to beat a dead horse, but nearly 100% of yoyo's seen are those where the kite rotates in the direction depicted in the above photos, or in the video posted.

I would love to be corrected, but IMHO rotating the kite around the inside (where the spreaders are) only occurs in a yo-fade style wrap.

@Jason01...what you are doing is a likely a 'down-yo'...wrapping directly out of a fade position. There, the kite is doing exactly the same thing, but in the down direction, rather than in the up direction.

The Next appears to have a lot more forward drive.
Good video BTW.

can we put a spreadsheet like something together?

I can state that the Transfer xtr is group B. With weight in the tail it's still group B 8)

|             |group A|group B|
|Next         |   x   |       |
|Next Team    |       |   x   |
|Transfer xtr |       |   x   |
