At Oshkosh 2013, we discovered the Panther, a single place aerobatic-capable LSA candidate. Company owner and designer Dan Weseman provides all the details you want to ask in this video. Pilots can expect a 1,500 fpm climb, fast takeoff, and enough strength for loops, rolls, and perhaps more (but check with the company's recommendations). Sold as a kit but meeting LSA parameters allows use of Sport Pilot certificate and the company will support many aircraft engine to the builder's desire.
