BEWARE - if this is the glider responsible, DON'T BUY IT, BURN IT.
I may be wrong, but if this glider was responsible for a very unfortunate fatality at Bicester, due to a problem with the rigging, it should be demolished.
The one I remember was so tricky to rig that when it was done ever so slightly incorrectly (and IMPOSSIBLE to confirm whether or not it was properly rigged)
on its SECOND launch that day, the wing came off.
And I seem to remember it was appropriately named a Foka.
Please, please, do your homework. If I am mistaken in my recollection I do apologise.
