I have a wipika airblast 8.9 too .... i was thinkink to make a bag or clothes
I think you mean an Airblast 8.4 (there is no 8.9) which is 8.4 x 1.36 = 11.4m2 in size
This very kite and size is IMO the best kite ever, seen over the whole "decade" of kitesurfing history
Of course not compared to newer kites, no - but overall my personal favorite of all kites during kite history.
A four line front line flyer, and can be relaunched backwards, or take it off and use it without - both options.
You can easily ride with this kite today, if you want to try - it has huge depower/windrange and quite fast and worked reasonably as a "one size quiver" in fact
PS: Or is it the Airblast 6.3 ? Which is 6.3 x 1.36 = 8.6m2 in size, and a VERY small kite actually, even though there were a 4.9 too (6.7m2) which were for gnarling winds back then.
