After testing a little less than a whole year and flying competitions, some minor modifications were done to the 2009 model.
On the website we have adjusted all the measurements and plans.
For pilots with a 2009 model it's just sufficient to make the tri-axis bridle,
slide the cross piece (center T) 1 cm higher, the APA's on the bottom leading edges 18 mm higher and shorten the upper spreader to 50 cm.
For new builders: just build what's on the plans.
The 2010 model is different from the 2009 STDi, they can coexist in your kitebag because they complement each other.
These plans will be put online between January 16 and 23.
