Hi Bo,
Thanks for all your postings regarding the Oreka. I think the LE of the wing was moved forward to accommodate the significantly increased sweep in the wing and keep the C/G in the same place. A little bigger fuselage, but not as large as some of the newer designs (maybe by a lot). I'm sure the mechanical airbrakes are very effective (the braking power of electrics is quite impressive). I suspect by keeping the design a bit 'smaller' this will allow for some reserve power if wind conditions require it. I, too, am anticipating video of the Oreka, but sometimes the line between aircraft design and pilot skills get pretty blurry.
