They have one, a single seater I think, up and running. Has maybe a 40 or 50 foot wingspan is all. I've seen it flying a couple of times in the last few months. It's been more or less complete since the late 90's, just waiting for some stuff to be built, rebuild, repaired, tuned, etc.
Might have another one. Seems I heard they did, but won't swear to it.
