Well, a lot of work has gone into it, but its not news worthy.
We will have that brown reworked prototype at the LSA booth in Oshkosh. But mainly we are building a second (read: brand new) one for our site.
I have 4 out of 6 of my staff (including myself) on its certification full time. Drawings are very nearly done. Analysis reports are in the works. Looks like just a Drop test for the gear and a pile of flight testing. I think we can bang most of it out in August, given the focus that we have on it.
