If you're not familiar with the Panther, reading this article in the Oct 2012 issue of the Experimenter will get you up to speed. The factory has a blog detailing the construction of the prototype here. What some may think is a bit unusual is that there are three beta builders already hard at building their own Panthers. And the prototype has yet to fly. Unusual? Not to those of us that remember that Sonex had five prototypes all under construction at the same time. The beta builders have a Yahoo group, so if you have Panther questions, that's the place to get them answered. Also, I've found Picasa a great way to chronicle a build. See the albums here. That's it for now.
