B-Series, B-Series Vented or Mid Vented?


Best Answer steveb, 25 June 2008 - 11:04 AM

I have 3 versions of the B-Series and have found that the Mid-Vent gets flown the most.
It does give up something at each end of the wind scale compared to the Full Sail and Vented, but it has been pure enjoyment in the range in between.
I would recommend a set of Race Rods and 4 Wrap Equipped, along with 50# light wind lines and 90# lines for maximum wind range.

If the winds are smooth and steady, the Full Sail definitely has the low wind advantage, but I've found that the Mid-Vent handles light and turbulent winds with more control. The Full Sail can be sensitive to poor winds and can tend to luff, where the Mid-Vent filters out a lot of the swirls and gusts and flies smoother in the bumpy stuff.

There are no free lunches- if you gain something at one end, you lose something else at another. The Full Vent can be slightly 'mushy' at times, where the Full Sail can be a bit 'skittish'. The venting filters out a lot of minor over-corrections and bumps in the wind, giving it a smooth and forgiving flight style. You do lose some of the Full Sail's quick response and tighter feel though.

IMO, the Mid-Vent is the best of both worlds. It keeps most of the strongest points of both models while not giving up too much at ether end.

Dave Ashworth has triple removable vent panels on one of his kites (he's only a builder though, having NEVER purchased a kite in the 8 or 10 years I've known him!) We like affecting the center portion of the sail best w/the venting on his model.

Adding covers over the venting is more weight to carry around though, . . . it's okay with a smooth 5mph, but low wind and the swirls make this option too much work. It's nice at the beach though, 'cause you can keep opening more and more vents as the wind increases throughout the day.

Hey folks, finally got over an hour on each version of the mid-vent...

Inner and outer venting, on 120' of 90, tons of brake as usual (see photo below).

midvent_handles.jpg

Flew with a 3 wrap frame in both kites...

All in a variable 6-12 mph at Delta Park in Portland, OR.

==

I'm here to tell you, outer vents is where it's at, at least in my opinion, modest as it is. ;)

==

midvent_inner.jpg

The inner vent gave me a bit of a Rev I kind of flight, where the right and left wings were arguing for control, two independent wings, flying on either side of very little sail... Corners for example, were very "dual-liney", turning around the wings.

Axels and flic flacs weren't as sweet as a vented, due to the wind resistance provided by the additional sail in the wings.

==

midvent_outer.jpg

The outer vents gave me every bit of the performance I'm accustomed to, and look for from the B-Series... Great control on the axis, stabilized the gusts and turbulence, better reverse and hovers than a standard, absolutely killer all in all.

Axels and flic flacs were almost as sweet as a full vented.

==

Rev made the right call in going to full-term production with the outer vent model, absolutely a great kite for the middle wind range.

You mean this will be part of the Revolution lineup :w00t: sweet deal.

Thanks for the description between the 2, much appreciated as I've been going out of my mind trying to decide between them.

But since you don't like the inner vented you can send it to me I'm sure I'll fine some use for it :kid_smartass:

Actually, I suppose it's premature to say "full production"...

I actually haven't confirmed that, but it seems a given at this point. ;)

As for the inner, well, it's got those neat little iQuad dudes all over it... Think I'll hold onto it. <grin>

Well I personally fly light. So even out doors I fly like I do indoors. So maybe the outter vented with the race rods might be what I want? Damn it, now I'm conflicted and it's all your all fault :w00t:

The Rev 1 seems like two sides fighting each other for control. The 1.5 I've flown with the 2 wrap rods and the std. both have been quicker to react to my input and easier to control. Hmmmmm, ask for help and make the decision harder. :w00t:
I know it's a B-Series, just which one? LOL. Guess I'll start with the Standard and work my way up? :huh: Someone make my mind up.

John? I've got the Rev 1, I could rerod it for light wind. But what do you think?

Dean :matrix:

P.S. I appreciate IQuad and all, but I'd almost rather conform to the norm than have an off looking panel on a kite. ;)

I was out at the field w/John today and I flew both of the mid vent kites as well :)

I enjoyed flying them both! B)
I really liked how the outer vent flew, better than the inner vent though and it seemed easier to control.

stabilized the gusts and turbulence, better reverse and hovers than a standard, absolutely killer all in all.

This description sounds good :P hehe.

I am yet to fly a full vent on the B-series.

well i havent flown the outer vent yet.. im still going with the fact that this inner is very enjoyable to fly .. john is right however it does have a rev 1 feel to it .. where the true test to this kite is is in the squirlly winds i still find this kite to handle the best for the sloppy winds i get inland.. the vents suck up the harder points when a full sail would handle like crap.. i do want to get an outer vent as well.. as nowthey are going into production.. the best part of my kite is the I QUAD dudes on it ha ha ha ha ha

From a design standpoint, I think I'd rather have the Iquad Dudes in that other panel over the grey material. If the kite only has one vent, is that oddball grey panel really necessary then? Sorry, this is just the arty side of my brain talkin.

In the right sky, it's hard to tell which panels are mesh and which are grey fabric. ;)

The inner grey panels give a consistent graphical match with other B-Series kites, too.

Voila, outer mid-vent in action...

http://video.google....401199214108405

Race frame, 3-6 mph, approximately 35' of 90#, using my 9" top leaders.

Just under 12 minutes worth of video, continuously filmed (uncut).

Please pardon the music, but it's not too bad for royalty-free. ;)

Hrm, Google cut the last half of the video off during the upload... Uploading again, should see music credits at the very end.

Is Viola what you call your mid-vent? An unusual name although I can see the links with a stringed instrument.

Personally I would have called it voila, but there it goes ;););)
