Parawing : making your own with a free DiY design software

Wing Foiling
1

How could Ensis/Gong/others be so fast to release a perfect parawing just 8 weeks after BRM ?

At 270€/$ psqm, do you find the parawing wings too expensive ? Can you use a sewing machine or want to learn ?
At 10€/$ psqm of 47gr PU coated polyester fabrics, making it could be the solution especially if you have a sewing machine or plan to buy one. A few hours to spare ?

Here are a couple of free DiY softwares that could be used to design your own parawing:
1 - Complex: Leparagliding: LEparagliding
FAQ: LEparagliding
Used in the first YT playlist here-below to design a Flysurfer PEAK clone

2 - More Simple: SingleSkin: SingleSkin download | SourceForge.net can be used with Sketchup 2017 (last free version)
3 - Paratailor PT9.0 (discontinued but if you can grab the v9.0 from May 2018)
4 - tbd
z - GliderPlan (Paying wing SW) by David Aberdeen, SurfPlan kitesurf design software

DiY Paragliders dedicated forums to get design files
1 - Paragliding Forum - View Forum - Software - new
2 - tbd
3 - tbd

If you know or use a free kite design sofware, pls write it below, share your experience and I will update this list

Playlist of two videos using Leparagliding SW. It would be interesting to get the PEAK clone data file and simplify it:

Videos using the SingleSkin design SW:
Andre Bandarra incredible design playlist called “Making a paraglider”

Ordinary DiYers don’t own a laser cuter to cut their spinaker so either use a laser printer and use a hot wire cutter :wink: or send their dxf file to a CNC shop.
11.3m2 projected area = 849 A4 sheets, 40 scotch tape rolls,

How to get plans and sewing practice ? Single skin paragliders plans measure between 15 and 25m2.
They could be reduced and their bridle tuned to the paraskiflex parawing type bar.
Then there is also RC paramotors wing plans available which are closer to the 3-6m2 surfaces we’re after.

Example:

Probably the most used for many years. SurfPlan

Newest inflateable design tool. KaroroCAD Online Home Page

Wouldn’t it be more feasible to adapt an existing product? Seems like a single skin foil kite, used most often for snow kiting) is best suited like what’s going on here > https://www.gumtree.com.au/s-ad/duncraig/surfing/flysurfer-peak-4-parawing-4m/1329008150

Nice wing and top manufacturing quality. However, looking at how much it is arched, one can see it hasn’t been designed to work with short lines… the bridle has still to be tweaked to improve the projected area

Guys seem to have gotten better results than this.

Agree with seagull_nz,
I am very happy with singleskin kite conversions, the inevitable kink in the arc is IMO not a big problem and is possible to be reduced by some more trim job, as allredy done.
But while planing further conversion maybe even up to high AR racekites.
The next project will be a complete DIY design, not shaped by me but Niklas:

who has already designed many DIY kites.

I just will try to sew his patterns together to extend my 4 - 2,5 m² range down to 2,2 m² and hope to show first results in the next weeks.
