There is a new plane from Marek a seller from Poland, designed specifically for FPV, that I bought and tested. Until now, I liked more than Skywalker (I have bought 3 Skywalker).
This is the link of the seller: http://abc-rc.pl/p/2/1573/model_ursu..._szybowce.html
and pictures of my construction posted at the Spanish FPV forum:
The plane is incredibly stable, faster than Skywalker, with lots of space and very good glide (maybe a little less than Skywalker)
