Some facts:
- Open source (plans will soon be available)
- Cheap frame (Exel cruise and 5pt LS)
- 205 cm wingspan
- designed for medium/strong winds but wil fly in lower windrange

Hope you'll be doing a build thread for the P2 as well! Love the b'zar 2011 thread,

Post by: sugarbaker on September 20, 2011, 04:30 PM
I would really like to do a build thread for the P2... I just downloaded the plans and will move it up on my build list just for that reason.  There are things I would like to improve with my own build process and I think this will be a great kite to document.

I'm inspired!  I am going to attempt to make one of these this winter!  :)

What are Exel Cruise?  Available in the USA?


Title: Re: P2 open source project - Updated
Post by: JimB on September 20, 2011, 07:53 PM
Probably not.

It's a high quality pultruded carbon rod.


Title: Re: P2 open source project - Updated
Post by: sugarbaker on September 20, 2011, 08:39 PM
the .240" (6.1mm) pultruded carbon available through a variety of places here in the states is similar in spec to the Exel Cruise rods recommended for this build.  They share the same inner diameter of 4mm and very close outer diameter.  I don't know much about the similarities in dynamics, but I've been perfectly happy with the pultruded carbon in my builds where it is required/recommended.


Title: Re: P2 open source project - Updated
Post by: Kareloh on September 20, 2011, 11:25 PM
I'll add that info to the frame specs.


Title: Re: P2 open source project - Updated
Post by: Allen Carter on September 21, 2011, 07:20 AM
the .240" (6.1mm) pultruded carbon available through a variety of places here in the states is similar in spec to the Exel Cruise rods recommended for this build.

The Avia .2400 pultrude commonly available here would generally be quite a bit heavier than good quality 6mm rods. .2300 is normally the best alternative, though some high mod 6mm are somewhat stiffer than Avia .2300.


Title: Re: P2 open source project - Updated
Post by: sugarbaker on September 21, 2011, 09:35 AM
I have purchased some .2300 rods in the past, and have had some variance in what I received. There are two different wall thicknesses available. (light or strong). The strong wall weighs approx the same as the .2400 rods (within a few grams for a 32.5). This bein the case, I've gone for the stiffer .2400 rods. As Allen has made a good point, if I can get the .2300 light wall rods, that may be the way I go for this build.


Title: Re: P2 open source project - Updated
Post by: Kareloh on September 21, 2011, 10:26 AM
A4 plans added.


Title: Re: P2 open source project - Updated
Post by: Allen Carter on September 21, 2011, 03:31 PM
The .2400 Avia rods are stiffer and heavier, but the increase in stiffness does not provide responsiveness as it might with other sticks. I've had a few .2400 framed kites, even framed a vented with them intentionally. They are just really dead feeling sticks. On a 2 meter kite like this they could be death. Probably be a double axel machine, though.


Title: Re: P2 open source project - Updated
Post by: Kareloh on September 21, 2011, 09:53 PM
The P2 is a Double Axel monster as is!


Title: Re: P2 open source project - Updated
Post by: JimB on September 21, 2011, 11:09 PM
Is there any reason not to use Skyshark P Series rods?

One could go up to P300 or 400 if the extra weight was crucial to the design.

P Series aren't all that stiff.

Post by: Krijn on September 22, 2011, 04:05 AM
Some facts:
- Open source (plans will soon be available)
- Cheap frame (Exel cruise and 5pt LS)
- ...


but why won't you just other rods?


Title: Re: P2 open source project - Updated
Post by: Kareloh on September 22, 2011, 04:22 AM
The Exel rods are widely availabe in this part of the world, so that's why the designers went with those... I don't see any reason besides the $ why not to use other rods.

Exel cruise is not THAT stiff. Structil would be a great substitute and i guess P or PT series skyshark would work very well.

As Krijn pointed out: It was designed to be a budget kite. With the provided framespecs it's almost unbreakable in normal flight/tricks in less then hurricane windspeeds (they've tried!).

That's the beauty of open source: just build it the way you like.

Wow. Very impresive.

I know I don't have the skills to fly like that.   :(

Wonder if I have the skills to sew a kite like that.  ::)

Thanks for the compliments.  8)

It is quite quick indeed, but it is manageble.
Some of the filming is a bit off, but i was glad there was at least somebody to hold the camera.

B'zar 2011 cameo in the posted video at 2:43.

Man I can't wait to finish my P2 builds, this kite looks like so much fun! (and I don't have many small kites like this).  Can't wait to try my different frame options either.  If only I could get some more time off of work!

I will be building a P2 for my wife. I am a bit undecided about the LE spars. I have ordered 60" long 6mm "strong" pultrude. These will be long enough to do the LEs in a single piece. Although, when we travel, breaking the kite down to a shorter length would be really nice. The OD of these rods is stated at .230" and the ID at .144". The question is, what would you suggest I use for ferrules if I decide to make the LEs break down?

Steve doesn't have the available sizes listed but he has the .2300" inside diameter - external ferrules are required for pultruded spars as they have no hoop strength and will split easily with an internal.


Title: Re: P2 open source project - Updated
Post by: AKA_MrBill on December 23, 2011, 09:19 PM
OK, here she is, and I use "She" quite literally. This is exactly what my wife wanted. I'll know in a few hours if I did it right.  ;)

It's not quite a standard build, but I am very satisfied with the results.

well done!  I'm sure your wife will be pleased!.  And you will (as stated) require external ferrules for the pultruded spars to have a 2 piece leading edge.

Finished P2... subject of P2 build thread.  This is the "beginner builders version" with 6mm pultruded leading edges (one piece), less detail in material and simpler aspects in terms of wing tip design, trailing edge design etc.  Here is completed kite.  Build thread lags behind, but more entries coming soon.

front, minus upper spreader

Hi Kareloh

My recently finished P2.

(http://img805.imageshack.us/img805/3374/20120227p2kitegwtw.jpg)

Icarex sail, P200 LE and spine, US is 6mm pultruded and LS are 5PT, roll bars are 3mm glass fibre.

Good medium wind kite, in 12 to 15 knot winds it has very little pull so can still do most slack line tricks just by walking forward which is ideal for a lazy flier like me.
